Scabies Outbreak Investigation and Risk Factors in East Badewacho District, Southern Ethiopia: Unmatched Case Control Study

Addressing scabies among street children in Ethiopia: an ethnographic study of acceptable interventions by prospective recipients and deliverers

Introduction

Scabies is a neglected tropical disease that affects the physical, socioeconomic, and psychological wellbeing of patients. Street children, due to poor living conditions and social marginalization, are at increased risk of infestation and face significant barriers to access healthcare services. Various interventions to control scabies have been suggested and implemented, but few have been based on the needs and viewpoints of the street children themselves. Drawing on the theoretical framework of acceptability (TFA), this article explores the interventions that street children, parents, and other key informants perceived to be appropriate to control scabies among street children.

Methods

An ethnographic approach was adopted to collect qualitative data from purposively selected street children, parents/caregivers, and key informants representing NGOs and the health and social sectors in Addis Ababa, Hawassa, and Adama. Rich data were gathered using FGDs, in-depth interviews, key informant interviews and drawing exercises, enhancing children's engagement in the study. Interviews were conducted in participants' preferred languages, recorded, transcribed verbatim, and translated into English for analysis. Data were coded by the two researchers who had collected them, and themes and sub-themes were identified.

Results

Living in overcrowded conditions, lack of access to sanitation materials and health services were among the priority needs and lived experiences of the street children. Providing peer-led health education, educating and mobilizing existing healthcare providers, preventing child streetism, raising the awareness of the community children migrate from, and providing sanitation facilities were among the proposed interventions that were considered appropriate to control scabies among street children.

Conclusion

Collaborative and participatory interventions that align with the lived experiences of street children and other stakeholders are likely to increase participation and enhance the feasibility and impact of scabies control and elimination efforts.

Prevalence of scabies and associated factors among school age children in Qoloji IDP in Babile district, Somali, Eastern Ethiopia

BACKGROUND

Scabies is a contagious ectoparasite of the skin. It is caused by the mite Sarcoptes scabiei var. Scabies occurs worldwide among people of all ages, races, genders and social classes and has been identified as a neglected tropical infectious disease. In Ethiopia, there is currently social unrest, conflict, and human-made disasters, leading to the displacement of the population from one place to another. Scabies is one of the most common skin diseases among the internally displaced population, where hygiene and sanitation are poor. The aim of the study was to assess prevalence of scabies and associated factors among school age children in Qoloji IDP in Babile District, Somali, Eastern Ethiopia.

METHODS

A cross-sectional community-based study design was carried out in 422 among school aged children from June to July 2022. The data was collected by using observation (clinical investigation), structured questionnaires. Data was coded, entered and cleaned using with epi data version 3.1, and exported and analysis was done by using SPSS statistical software package version 22. Logistic regression analysis was used to identify factors associated with scabies. Findings were presented by using 95% CI of Crude Odds Ratios (COR) and Adjusted Odds Ratios (AOR). To declare statistical significance, a p-value of less than 0.05 was used.

RESULTS

There were 63 cases of scabies with a prevalence of 14.92% CI at 95% (11.7%-18.1%). The multivariable logistic regression shows that age categories with 5-9 [AOR = 2.4 (95% CI: 1.01,6.39)], over-crowding index greater than 1.5 [AOR = 10 (95% CI: (3.6,27.8)] washing clothes infrequently [AOR =  14.7(95% CI: 3.6,25)), history of contact with scabies patients in the past 2 months [AOR =  5(95% CI: (1.2,23.0)], and Family having rash in the past two weeks [AOR = 9.9 (95% CI: 3.7,26)] having poor knowledge about scabies among children's family [AOR = 8.9 (95% CI: 3.3,24)] were significant variables at p-value less than 0.05.

CONCLUSION

There was a higher prevalence of scabies in the study area. Age, overcrowding, washing clothes infrequently, history of contact with scabies patients in the past 2 months, family having a rash in the past two weeks, and poor knowledge about scabies among children's families were significant factors. Health education on personal hygiene, avoiding sharing clothes with others, avoiding contact, sleeping with scabies-ill people, and sharing beds with others are important measures in reducing these risk factors.

Prevalence and determinants of scabies: A global systematic review and meta-analysis

OBJECTIVES

Scabies is a neglected skin disease that disproportionately affects people from resource poor and overcrowded countries. Global data on prevalence and risk factors are limited. This article aims to estimate the global burden of scabies and identifies the risks associated with it.

METHODS

Databases (PubMed, Scopus and Cochrane Reviews) were accessed to identify studies of scabies prevalence published between 2000 and 2024. Results were pooled to estimate prevalence and identify factors, which explained between-study heterogeneity. Odds ratios (ORs), risk of bias, subgroup analyses and meta-regression were used to describe variation in effect size and heterogeneity based on country-level demographic and economic variables.

RESULTS

Seventy studies yielded a pooled prevalence of 11.9% (95% confidence interval [CI]: 9.60-14.7) with substantial heterogeneityI 2 = 100 % τ 2 = 1.04 . Prevalence was highest in Oceania (17.9%; 95% CI: 13.9-22.8) compared to other regions. Pooled risk factors for scabies showed significant associations for demographic and behavioural factors including contact history with household members with itch (OR 11.3; 95% CI 4.82-26.51;I 2 = 96 % ; n = 7), lack of soap use (OR 3.41; 95% CI: 2.56-4.54;I 2 = 44 % ; n = 7), bed-sharing (OR 2.64; 95% CI: 1.50-4.63;I 2 = 76 % ; n = 7), sharing of clothes (OR 2.52; 95% CI: 1.58-4.03;I 2 = 85 % ; n = 7), infrequent bathing (OR 2.13; 95% CI: 1.41-3.22;I 2 = 77 % ; n = 6), presence of pets (OR 1.76; 95% CI: 1.08-2.87;I 2 = 84 % ; n = 4) and being a male (OR = 1.19; 95% CI: 1.04-1.37;I 2 = 83 % ; n = 22). Socioeconomic factors were not convincingly associated with scabies prevalence.

CONCLUSION

Prevalence of scabies is associated with geographic location and behavioural factors, but not between-country socioeconomic status. In addition to mass drug administration, risk factors are identified which may be included in health promotion programmes to reduce scabies prevalence and its sequelae in the long term.

Assessment of scabies and its associated factors in Hawassa Zuria District, Southern Ethiopia: A cross-sectional study

BACKGROUND

Scabies is a common but neglected skin disease caused by the parasitic mite Sarcoptes scabiei var. hominis. Globally, the disease affects more than 400 million people. Although Ethiopia is a high-burden country for scabies, its epidemiology has not been well assessed. Therefore, this study aimed to determine the prevalence of scabies, clinical features, and associated risk factors in the communities of the Hawassa Zuria District of the Sidama Region, southern Ethiopia.

METHODS

A community-based cross-sectional study was conducted from September through November 2023 in the Hawassa Zuria District. A multistage random sampling technique was applied to enrol 511 participants. The International Alliance for Control of Scabies Diagnostic Criteria was used for examination. The data were collected electronically using the Open Data Kit application through a pretested interviewer-administered questionnaire. Analysis was performed using STATA software. The binary logistic regression analyses model was used to assess the association between each independent variable and scabies prevalence. During the bivariate logistic regression analyses a variable with a p-value of < 0.25 was a candidate for multivariable logistic regression analyses. In multivariable logistic regression analyses the odds ratios with a 95% confidence interval and a p-value less than 0.05 were used to describe the strength of the association and statistical significance.

RESULTS

The median age of the study participants was 19 years (interquartile range: 11-32 years), and 52.6% of the participants were females. The overall prevalence of scabies was 6.3% (95% CI 4.3-8.7%). The majority of individuals with scabies had a moderate degree of severity. The most frequent lesions were intensely itchy papules, vesicles, and pustules that appeared in the interdigital space, flexor wrist surfaces, and elbow. Males were more likely to have scabies [adjusted odds ratio (AOR) = 2.57; 95% CI: 1.10-6.00] than females were and it was not influenced by age. The risk of scabies was higher for households with low (AOR = 3.88; 95% CI: 1.01-14.91) and middle-class wealth index (AOR = 4.43; 95% CI: 1.13-17.33), as well as for individuals residing in households with an overcrowding index >1.5 (AOR = 2.64; 95% CI: 1.13-6.18), in those individuals who washed their hands with water only (AOR = 2.98; 95% CI: 1.23-7.24), in those who used an unimproved water source (AOR = 2.98; 95% CI: 1.25-7.06) and in those who slept on the floor (AOR = 2.70; 95% CI: 1.17-6.18).

CONCLUSION

The observed moderate presence of scabies in the study area stresses the need to strengthen disease management efforts, improve wealth, reduce overcrowding, ensure clean water access, and promote better hygiene practices to reduce the spread of scabies.

Burden and determinants of scabies in a pastoralist community: a case-control study from Southwest Ethiopia

BACKGROUND

Scabies is a skin infestation caused by the human itch mite, affecting people globally across all demographics. However, it is more prevalent among children, individuals with poor hygiene, those in overcrowded or slum areas and people affected by drought and war. There is limited research on scabies in Ethiopia and none specifically focused on marginalised communities. This study aimed to assess the burden of scabies and its contributing factors among pastoralist communities in Ethiopia.

METHODS

A community-based, unmatched case-control study (1:2 ratio) was conducted in Meinit Goldiya District to assess risk factors for scabies. The researchers collected line-listed data on scabies and conducted face-to-face interviews from January to February 2023, with a sample of 156 cases and 312 controls. Data were gathered using a structured questionnaire and analysed with SPSS V.22. OR, p values and 95% CI were calculated to identify associated factors. Independent factors were determined using a p value of <0.05 and the corresponding 95% CI in the multivariable model.

RESULTS

A total of 4269 scabies cases were reported in the district, with an attack rate of 7.9%. Of the reported cases, 52.8% (2254 cases) were male. The multivariable analysis identified several factors significantly associated with scabies: sleeping with infected individuals (adjusted OR (AOR)=3.70 (2.08, 6.61)), sharing washing facilities with patients with scabies in the past 6 months (AOR=4.05 (2.30, 7.13)), placing clothes together with infected individuals' clothes (AOR=4.71 (2.64, 8.42)) and households with a daily water consumption of ≥25 L per person per day, which was a protective factor (AOR=0.06 (0.03, 0.12)).

CONCLUSION

Scabies is a public health issue in the district, with significant risk factors including sleeping, washing and contact with patients with scabies, as well as daily water consumption levels. To address this, the study recommends strengthening active case surveillance, offering health education and ensuring health facilities are stocked with treatment medications.

Prevalence and Determinants of Scabies Among Schoolchildren in Ethiopia: A Systematic Review and Meta-Analysis

BACKGROUND AND AIMS

In deprived and poor communities worldwide, scabies remains an overlooked tropical disease. Numerous individual studies have been conducted in Ethiopia on this issue, demonstrating notable disparities and inconclusive findings. This systematic review and meta-analysis aimed to establish Ethiopia's pooled scabies prevalence and determinants among schoolchildren.

METHODS

Studies were retrieved from PubMed, Scopus, Science Direct, Google Scholar, and African Journals Online through a systematic search. The Joanna Briggs Institute's critical appraisal tool was employed to assess the quality of observational studies (cross-sectional and case-control). The meta-analysis was performed using Stata software version 14 and its metan command. A forest plot was used with a random effects model to calculate the pooled prevalence and its 95% confidence interval (CI). Subgroup and sensitivity analyses were employed to evaluate potential sources of heterogeneity. The funnel plot and Egger's test were used to evaluate publication bias, while heterogeneity was assessed using inverse variance (I 2).

RESULTS

In this systematic review and meta-analysis, 14.71% (733/5104) of schoolchildren had scabies, with a 95% CI of 8.90%-20.52%. The highest prevalence is recorded in the Amhara region (17.09%; 95% CI: 2.15-32.04), and the lower prevalence is seen in the Oromia region (12.52%; 95% CI: 10.08-14.95). Children sharing clothes with scabies cases, using common sleeping beds/fomites, having a family history of scabies, and having illiterate parents are significantly associated with scabies among Ethiopian schoolchildren (based on adjusted odds ratios: 7.07; 95% CI: 1.55-12.59, 2.13; 95% CI: 0.04-4.22, 1.45; 95% CI: 0.35-3.94, 1.42; 95% CI: 0.94-0.89).

CONCLUSION

The current prevalence of scabies ranges from 12.52% to 17.09% and is higher in the Amhara region. The national policymakers and health planners should prioritize implementing prevention and control measures of scabies among schoolchildren through ivermectin-based mass drug administration for three to five rounds annually until the prevalence is less than 2%.

Prevalence and determinants of scabies among schoolchildren in Africa: A systematic review and meta-analysis

BACKGROUND

Scabies is one of the major neglected tropical diseases among children in deprived communities. Studies conducted among schoolchildren in Africa are limited and inconsistent. Thus, the aim of this study is to estimate the pooled magnitude and predictors of scabies in African schoolchildren.

METHODS

The pooled prevalence estimate with 95% confidence intervals was performed using a random-effects model. Heterogeneity between studies was assessed using the I 2 statistic. Subgroup analyses and sensitivity analyses were performed to explore potential sources of heterogeneity. Publication bias was evaluated using the funnel plot, Begg's, and Egger's tests.

RESULTS

A total of 28,482 subjects from 19 studies were included. The pooled prevalence of scabies among African schoolchildren was 10.81% (2459/28482) with (95% CI: 7.10-14.51). Factors such as being male (aOR = 1.86; 95% CI: 0.72-3.01), children who have a history of sharing clothes with their family (aOR = 1.76; 95% CI: 0.62-2.91), having illiterate parents (aOR = 0.96; 95% CI: 0.51-1.41), having history of contact with skin itching cases/scabies (aOR = 3.37; 95% CI: 1.70-5.03), infrequent cloth wash (aOR = 5.30; 95% CI: 1.26-9.34), sharing common sleeping beds/fomites (aOR = 2.13; 95% CI: 0.04-4.22), family member with itchy signs/scabies (aOR = 5.83; 95% CI: 1.45-10.21), and not taking a bath with water and soap (aOR = 8.51; 95% CI: -4.14 to 21.15) were factors associated significantly with scabies.

PROSPERO REGISTRATION

CRD42024542762.

CONCLUSION

In the present scenario, scabies ranges from 2.0% to 17.80% and is higher in Cameroon. Therefore, policymakers and health planners should put a great deal of emphasis on the implementation of relevant prevention and control measures.

Scabies

Scabies is one of the most common and highest-burden skin diseases globally. Estimates suggest that >200 million people worldwide have scabies at any one time, with an annual prevalence of 455 million people, with children in impoverished and overcrowded settings being the most affected. Scabies infection is highly contagious and leads to considerable morbidity. Secondary bacterial infections are common and can cause severe health complications, including sepsis or necrotizing soft-tissue infection, renal damage and rheumatic heart disease. There is no vaccine or preventive treatment against scabies and, for the past 30 years, only few broad-spectrum antiparasitic drugs (mainly topical permethrin and oral ivermectin) have been widely available. Treatment failure is common because drugs have short half-lives and do not kill all developmental stages of the scabies parasite. At least two consecutive treatments are needed, which is difficult to achieve in resource-poor and itinerant populations. Another key issue is the lack of a practical, rapid, cheap and accurate diagnostic tool for the timely detection of scabies, which could prevent the cycle of exacerbation and disease persistence in communities. Scabies control will require a multifaceted approach, aided by improved diagnostics and surveillance, new treatments, and increased public awareness.

Analysis of the Scabies Incidence at As'ad Islamic Boarding School, Jambi City

Scabies is an infectious disease. Based on preliminary observations, numerous scabies sufferers have been found among students living in As'ad Islamic Boarding School, Jambi City, Indonesia. Scabies disease develops in humans and can be influenced by both human factors and the environment. This study aims to identify factors associated with scabies incidence at the As'ad Islamic Boarding School. This analytical observational research was conducted using a cross-sectional study design. The variables measured were scabies symptoms, knowledge, personal hygiene, contact history, humidity, and room occupancy density. The research samples consisted of 178 students at the As'ad Islamic Boarding School in Jambi City, who were selected randomly. The required data were collected by questionnaires and analyzed by Chi-square test and logistic regression. Most of the students had crowded living conditions (94.4%), low room humidity (80.8%), poor personal hygiene (66.3%), a low level of knowledge about scabies (70.8%), contact with scabies sufferers (61.8%), and symptoms of scabies (60.7%). Symptoms of scabies were related to knowledge (P=0.000), personal hygiene (P=0.000), contact history (P=0.000), humidity (P=0.000), and room occupancy density (P=0.001). The incidence of scabies in students at the As'ad Islamic Boarding School was influenced by insufficient knowledge, poor personal hygiene, history of contact, low humidity, and overcrowding.

Scabies prevalence and its associated factors among prisoners in southern Ethiopia: An institution-based analytical cross-sectional study

BACKGROUND

Scabies is an ectoparasitic infestation that can easily spread during close human contact and in overcrowded areas such as prisons and public places where sanitation is a problem. Globally, as many as 300 million people are infested with scabies each year. Within Ethiopia, its burden in institutions like prisons is not well-studied. As a consequence, we sought to estimate the prevalence of scabies and also identify factors associated with it among prison inmates in southern Ethiopia.

METHODS

An institution-based analytical cross-sectional study design was employed. We used, a simple random sampling technique to select 422 prisoners. A pretested-structured questionnaire was used to collect the necessary information. EpiData version 4.2.0.0 and Statistical Packages for Social Science version 25 software were used for data entry and analysis respectively. Both descriptive and inferential statistics were computed. The model fitness was checked using the Hosmer-Lemeshow and omnibus tests. The association between the independent and outcome variables was presented in the form of a table showing the crude odds ratio and adjusted odds ratio (AOR) along with their 95% confidence interval (CI). The level of statistical significance was declared at P.value ≤ 0.05.

RESULTS

A total of 418 prisoners were interviewed, yielding a 99.1% response rate. The age of the participants ranged from 17 to 60 years. As many as 381 (91.1%) participants were male. The prevalence of scabies was found to be 8.9%. A history of sexual contact in the past two months, before imprisonment (AOR: 9.92 (95% CI 3.07, 32.02), P <0.001), a period of stay less than two months duration in the prison (AOR: 4.54 (95% CI 1.51, 13.54), P = 0.007), poor ventilation (AOR: 3.36 (95% CI 1.07, 10.58), P = 0.038), lack of hygiene soap (AOR: 5.53 (95% CI 1.45, 21.17), P = 0.012), and sharing clothes among each other (AOR: 3.81 (95% CI (1.09, 13.29), P = 0.036) were factors independently associated with a scabies infestation.

CONCLUSION

In this study, we found the prevalence of scabies was high among prison inmates in Wolaita Zone prison. Furthermore, scabies infestations were associated with a previous history of sexual contact, poorly ventilated rooms, lack of hygiene soaps for washing, and sharing clothes amongst the inmates. Prison administrations should be encouraged to improve sanitary and screening and isolation of prisoners during imprisonment.

Healthcare users' knowledge and experiences regarding the management of scabies in the Deder district, Ethiopia

BACKGROUND

Scabies is an ectoparasitic, highly contagious skin disease caused by a human itch mite infestation of the skin, and it is the leading cause of morbidity and disease burden in developing countries. The purpose of this study was to investigate healthcare users' current knowledge and experiences with scabies management provided at primary healthcare facilities.

MATERIALS AND METHODS

A qualitative research design was used to address the research objectives. Focus group interviews with 58 health care users were used to collect data. Thematic analysis was performed on the verbatim transcriptions using Tesch's approach.

RESULTS

The findings showed that the knowledge of healthcare users who participated in the study on scabies, its management, prevention, and control was limited. Health care users experience different challenges regarding scabies and the management thereof. Five themes emerged after data analysis. These were knowledge regarding scabies, knowledge regarding the management of scabies, knowledge regarding the prevention of scabies, perceptions regarding receiving treatment for scabies, and recommendations regarding the availability of materials and medication.

CONCLUSIONS

Healthcare users in the area had limited knowledge and experienced different challenges regarding scabies and their management. These challenges contribute to low-quality health services with undesirable health outcomes. To narrow this gap, consistent and programed health education was provided to the community through different modalities by using the existing health system to increase awareness regarding scabies. Following the implementation of community awareness, each community member was positioned to prevent and control scabies.

Scabies in the Amhara region of northern Ethiopia: a cross-sectional study of prevalence, determinants, clinical presentation and community knowledge

BACKGROUND

The WHO aims to prevent, eliminate or control neglected tropical diseases, including scabies, by 2030. However, limited epidemiological data presented a challenge to control efforts, especially in high burden countries. There was a major scabies outbreak in northern Ethiopia starting in 2015 and prevalence has since increased across much of the country.

OBJECTIVE

To estimate scabies prevalence, identify its predictors, and assess community perception of, and knowledge about, the infestation.

DESIGN

Population-based cross-sectional study.

STUDY SETTING

Ayu Guagusa district, Amhara region, northern Ethiopia.

PARTICIPANTS

1437 people who were members of 381 randomly selected households participated in the study. Five trained mid-level health workers clinically diagnosed people with scabies.

OUTCOME MEASURES

Clinically diagnosed scabies infestation.

DATA ANALYSIS

Multi-level logistic regression models were fitted to adjust for individual and household-level confounding variables, and identify predictors of scabies infestation.

RESULTS

Scabies prevalence was 13.4% (95% CI 11.8 to 15.5). Households of more than five people (adjusted OR (aOR)=3.5, 95% CI 1.2 to 10.2) were associated with increased odds of developing scabies, however, females had lower odds (aOR=0.5 95% CI 0.3 to 0.8). Scabietic lesions most frequently involved the trunk (62.0%), and vesicles were the most common types of lesions (67.7%). Two-thirds of adult study participants had heard about scabies and most obtained scabies related information from informal sources. Only 32% of cases sought care for scabies from any source.

CONCLUSION

Scabies prevalence was high, signifying the need for community-based control interventions. Host density and sex were important predictors of scabies. Despite the favourable attitude toward the effectiveness of scabies treatment, healthcare seeking was low.

Prevalence and determinants of scabies among school-age children in Central Armachiho district, Northwest, Ethiopia

Background

Scabies is a major global public health issue that might affect people from all socioeconomic levels. Globally, scabies affects more than 200 million people at any time. It remains one of the commonest skin diseases seen in developing countries including Ethiopia. Therefore, this study aimed to assess the prevalence and determinants of scabies among school-age children in Central Armachiho district, Northwest Ethiopia.

Methods

A community-based cross-sectional study was conducted from August to September 2020. A multi-stage sampling technique was used to select 850 study populations. Data was checked for its completeness, coded, and entered by using EPI-INFO version 7 and exported to the SPSS version 20 for analysis. A Binary logistic regression model was fitted to identify the determinants of scabies. Crude odds ratio (COR) and adjusted odds ratio (AOR) with 95% CI were used as measurements for the associations. P-values <0.005 were considered significant.

Result

Prevalence of scabies among the 850 participants studied was 10.82% (95% CI: 8.7–12.9). Contact history with confirmed scabies patient (AOR = 5.28,95% CI: 2.96–9.44), child not attending school (AOR = 3.08, 95% CI;1.45–6.54), rarely changing clothes (AOR = 2.43,95% CI: 1.27–4.62), sleeping on the floor (AOR = 4.11, 95% CI:1.95–8.67), bed sharing; (AOR = 3.38, 95% CI:2.86–6.15), rarely washing cloth: (AOR = 5.08,95% CI:2.75–9.36), living with internally displaced people; (AOR,95% CI: 3.47 (1.30–9.24) and using only water to wash hands; (AOR = 3.18,95% CI:1.74–5.80) had a statistically significant association with scabies infestation among school-age children.

Conclusion

The current study found nearly one out of ten school-age children had scabies. Not attended school, contact history with confirmed scabies patient, not washing cloth, infrequent changing clothes, bedding sharing, sleeping on the floor, living with internally displaced people, and only using water for handwashing practice were the independent predictors for the occurrence of scabies. Health education better to given to the parents or caregivers about the washing of clothing, changing clothes at least once per week, and avoid physical contact with known scabies cases.

Epidemiology of floods in sub-Saharan Africa: a systematic review of health outcomes

BACKGROUND

Floods have affected 2.3 billion people worldwide in the last 20 years, and are associated with a wide range of negative health outcomes. Climate change is projected to increase the number of people exposed to floods due to more variable precipitation and rising sea levels. Vulnerability to floods is highly dependent on economic wellbeing and other societal factors. Therefore, this systematic review synthesizes the evidence on health effects of flood exposure among the population of sub-Saharan Africa.

METHODS

We systematically searched two databases, Web of Science and PubMed, to find published articles. We included studies that (1) were published in English from 2010 onwards, (2) presented associations between flood exposure and health indicators, (3) focused on sub-Saharan Africa, and (4) relied on a controlled study design, such as cohort studies, case-control studies, cross-sectional studies, or quasi-experimental approaches with a suitable comparator, for instance individuals who were not exposed to or affected by floods or individuals prior to experiencing a flood.

RESULTS

Out of 2306 screened records, ten studies met our eligibility criteria. We included studies that reported the impact of floods on water-borne diseases (n = 1), vector-borne diseases (n = 8) and zoonotic diseases (n = 1). Five of the ten studies assessed the connection between flood exposure and malaria. One of these five evaluated the impact of flood exposure on malaria co-infections. The five non-malaria studies focused on cholera, scabies, taeniasis, Rhodesian sleeping sickness, alphaviruses and flaviviruses. Nine of the ten studies reported significant increases in disease susceptibility after flood exposure.

CONCLUSION

The majority of included studies of the aftermath of floods pointed to an increased risk of infection with cholera, scabies, taeniasis, Rhodesian sleeping sickness, malaria, alphaviruses and flaviviruses. However, long-term health effects, specifically on mental health, non-communicable diseases and pregnancy, remain understudied. Further research is urgently needed to improve our understanding of the health risks associated with floods, which will inform public policies to prevent and reduce flood-related health risks.

Determinants of scabies outbreak in Takusa district of Amhara Region, Northwest Ethiopia

Background

Human scabies is a highly contagious human dermatitis disease. As indicated by the national and regional reports, the epidemic of scabies became a major public health problem in Ethiopia since 2015.

Objective

To identify the determinant factors of scabies outbreak in Takusa district, Northwest Ethiopia, 2017.

Methods

A community based unmatched case-control study among 188 participants (63 cases and 125 controls) was conducted in Takusa district from September to October 2017. Data were collected using a pretested structured questionnaire. Multivariable logistic regression analysis was computed using SPSS version 22 to identify factors associated with scabies. Odds ratio at 95% CI and p-value less than 0.05 were used to describe the strength of the association and statistical significance.

Results

The median age of cases was 20 years (ranges1-61). Presence of person with itching in the family (AOR=7.7, 95% CI:1.9-30.5), sleeping with scabies patient (AOR=3.99, 95% CI:1.37-11.7), travel to scabies epidemic area in the last six weeks (AOR=3.79, 95%CI:1.28-11.1) and infrequent use of detergent for showering (AOR=4.85; 95% CI: 1.3-17.9)) were found to be determinant factors of scabies outbreak.

Conclusion

Frequent contact with people who develop scabies at home, not using detergents for washing, and mobility of people from non-epidemic to the epidemic areas were determinant factors. Giving special emphasis on regular awareness creation to the rural community is important to prevent scabies outbreak.

Scabies and its associated factors among under 15 years children in Wadila district, Northern Ethiopia, 2019

INTRODUCTION

scabies is a contagious ectoparasite of the skin. It is caused by the mite Sarcoptes scabiei var. hominis that causes a pruritic skin eruption. It was estimated that more than 300 million cases of scabies occur worldwide every year. It remains one of the commonest skin diseases seen in developing countries including Ethiopia. Therefore, the main aim of this study is to determine scabies prevalence and its associated factors among less than 15 years children in Wadila district, Northern Ethiopia.

METHODS

community based cross-sectional study was conducted on 583 participants from January 30th to February 28th 2019. Multistage sampling technique was used and data were collected using pre-tested interviewer administered questionnaire. SPSS version 23.0 was used for analysis and bivariable logistic regression was computed and variables having p < 0.25 was modelled in multi-variable logistic regression to control confounders. The level of statistical significance was set at p < 0.05.

RESULTS

the prevalence of scabies infestation was 23.8% in Wadila district. Not using of soap when taking shower [AOR=2.93 (95% CI:1.72-5.00)], using unimproved water source [AOR=1.82 (95% CI:1.04-3.16)], sharing clothes from scabies cases [AOR=10.10 (95% CI: 3.37-30.23)], uncleaning of the house every day [AOR=2.28 (95% CI: 1.32-3.95)], presence of pet animals at home [AOR= 3.01(95% CI: 1.66-5.45)] and went to epidemic areas of scabies [AOR= 4.09 (95% CI: 2.37-7.06) were predictors of scabies infestation.

CONCLUSION

there was higher prevalence of scabies infestation in Wadila district. Therefore, special attention should be given to under 15 years children.

Prevalence and associated factors of scabies in Ethiopia: systematic review and Meta-analysis

BACKGROUND

Scabies is an infectious disease that affects the skin caused by the mite Sarcoptes scabiei and it transmitted through close personal contact. Even though it is easily treatable disease, its prevalence is high and continuous as neglected tropical disease of resource-poor settings, and particularly affects young age groups. Despite of these facts, studies conducted in Ethiopia regarding to the prevalence and associated factors for scabies infestation have been highly variable and didn't well compiled. Due to that, the aim of this systematic review and meta-analysis was to estimates the overall prevalence of scabies and associated factors in all age groups in Ethiopia.

METHODS

International databases (PubMed/PMC/Midline, EMBASE, CINAHL, Web of Science, Google Scholar, Google and Science Direct) were systematically searched from December 1, 2019, to January 18, 2020. All observational studies noted the prevalence of human scabies and associated factors in Ethiopia were included. Two authors (AG and G.T) independently extracted all necessary data using a standardized data extraction format. The data which is extracted each study were analyzed using STATA Version 14.1. Heterogeneity among the included studies was assessed through the Cochrane Q test statistics and I2 test. Lastly, a random effects meta-analysis model was computed to fix overall prevalence and associated factors of scabies.

RESULTS

Twelve studies were included in this meta-analysis after 410 articles retrieved. Of these, eight studies were analyzed for prevalence estimation. The overall prevalence of scabies infestation was 14.5% (95%CI: 1.5, 27.6%) in Ethiopia. Furthermore, the subgroup analysis revealed the highest prevalence was 19.6% in Amhara region. A person from a large family size (OR: 3.1, 95% CI: 1.76, 5.67), and sharing a bed (OR: 3.59, 95%CI: 2.88, 4.47) were significantly associated with scabies.

CONCLUSION

This study revealed the prevalence of scabies infestation was 14.5% in Ethiopia which was high. Persons from high family size and any contact with scabies case were factors associated with scabies.

Factors associated with scabies outbreaks in primary schools in Ethiopia: a case-control study

Background

Scabies is a neglected tropical disease affecting more than 200 million people worldwide every year. Scabies in school adolescents and young adults could affect their school performance. The current study investigates the factors associated with an outbreak of scabies at primary schools in southern Ethiopia.

Method

A team of health professionals investigated an outbreak of scabies that occurred in primary schools from May 1 to 30, 2018. An unmatched case–control study was employed to assess factors which predisposed for the scabies outbreak. Cases of scabies were individuals having a skin lesion compatible with the WHO case definitions of scabies. Controls were from the same locality with no skin lesions. Data on sociodemographic and behavioral variables were collected using questionnaires. Data on clinical presentations of scabies among cases were recorded by two trained and experienced health professionals. Factors associated with scabies were assessed using bivariate and multivariate logistic regression, and strength of association was described using odds ratio (OR) and 95% confidence intervals (CIs).

Results

A total of 711 (237 cases and 474 controls) study subjects participated in the study. The mean age of study participants was 17.56±2.66 years. Poor knowledge about scabies, adjusted odds ratio (AOR)=4.32 (95% CI: 2.93, 6.36); male sex, AOR=2.69 (95% CI: 1.82, 3.96); and parental illiteracy, AOR =3.49 (95% CI: 2.06, 5.94) predicted scabies infestation. Additionally, socioeconomic variables like sharing clothes/beds or contact with others, AOR=3.12 (95% CI: 2.12, 4.59); low household annual income, AOR=2.13 (95% CI: 1.32, 3.44); and family size greater than five, AOR=1.77 (95% CI: 1.04, 3.01) were significantly associated with scabies infestation. Inaccessibility and poor utilization of water, AOR=1.64 (95% CI: 1.12, 2.40) and poor personal hygiene, AOR=1.69 (95% CI: 1.14, 2.51) were also factors independently associated with scabies.

Conclusion

Modifiable risk factors such as personal hygiene and literacy level were found to be independent predictors of scabies infestation. Access to and utilization of water were also important predictors. Strategies for poverty alleviation and awareness creation on personal hygiene and efficient use of water are recommended for effective prevention of scabies infestation in closed institutions.

Ectoparasites: Scabies

Scabies is an ectoparasitic dermatosis caused by Sarcoptes scabiei var. hominis and is a public health issue in all countries regardless of socioeconomic status. In high-income countries, delays in diagnosis can lead to institutional outbreaks; in low- and middle-income countries, poor access to health care contributes to disease undertreatment and long-term systemic sequelae. With scabies now recognized as a neglected tropical disease by the World Health Organization, increased awareness and systematic efforts are addressing gaps in diagnosis and treatment that impede scabies control. This review summarizes the available data and provides an update on scabies epidemiology, clinical features, diagnosis, management, and public health considerations.

Scabies outbreak investigation and risk factors in Kechabira district, Southern Ethiopia: unmatched case control study

Objective

Scabies is an infection of the skin, which caused by human itch mite Sarcoptes scabiei. It is a common health problem in Ethiopia, especially during disasters, poor sanitation and overcrowded living condition. However, investigation on scabies outbreak and associated factors was absent or scarce in the country in general and in the study area in particular. Hence, this study was intended to investigate scabies outbreak, identify risk factors, and recommend preventive measures in Kechabira district, Kembata Tembaro zone, Southern Ethiopia.

Result

We identified a total of 243 scabies cases line listed with overall prevalence of 2.5% and attack rate of (AR) 20.5 per 1000 populations and no death was reported. Of the suspected cases 126 (51.9%) were males and 117 (48.1%) were females. The median age was 24 years with inter-quartile range (IQR) of 22 years. The highest cases were seen in children aged 5–14 (50.6%) years. The cases were seen in three villages and the highest incidence was in Burchana, 23.9 per 1000 population. Identified determinant factors for scabies outbreak were sharing clothes with scabies patients (AOR = 6.08, 95% CI [1.54–23.92], and households having greater than six family members AOR = 38.755, 95% CI [8.084–185.787].
