COVID-19 in Oromia Region of Ethiopia: a review of the first 6 months' surveillance data

COVID-19 mortality rate and its determinants in Ethiopia: a systematic review and meta-analysis

Background

The COVID-19 mortality rate continues to be high in low-income countries like Ethiopia as the new variant's transmission expands and the countries' limited capacity to combat the disease causes severe outcomes, including deaths. The aim of this study is to determine the magnitude of the COVID-19 mortality rate and its determinants in Ethiopia.

Methods

The main electronic databases searched were PubMed, CINAHL, Google Scholar, and African journals online. The included studies' qualities were assessed independently using the Newcastle-Ottawa scale. The data was extracted in Microsoft Excel spreadsheet format. The pooled effect size and odds ratios with 95% confidence intervals across studies were determined using the random-effects model. I2 is used to estimate the percentage of overall variation across studies due to heterogeneity. Egger's test and funnel plot were used to find the published bias. A subgroup analysis was conducted. The effect of a single study on the overall estimation was determined by sensitivity analysis.

Results

A total of 21 studies with 42,307 study participants were included in the final analysis. The pooled prevalence of COVID-19 mortality was 14.44% (95% CI: 10.35-19.08%), with high significant heterogeneity (I2 = 98.92%, p < 0.001). The risk of mortality from COVID-19 disease was higher for patients with comorbidity (AHR = 1.84, 95% CI: 1.13-2.54) and cardiovascular disease (AHR = 2, 95% CI: 1.09-2.99) than their counterparts without these conditions.

Conclusion

A significant number of COVID-19 patients died in Ethiopia. COVID-19 patients with comorbidities, particularly those with cardiovascular disease, should receive special attention to reduce COVID-19 mortality.

Rapid antigen test as a screening tool for SARS-CoV-2 infection: Head-to-head comparison with qRT-PCR in Ethiopia

Objective

This study aimed to determine the diagnostic accuracy of the antigen rapid diagnostic test (Ag-RDT) as a screening tool for SARS-CoV-2 infection compared to Quantitative reverse transcription polymerase chain reaction (qRT-PCR).

Methods

This study was conducted at six referral hospitals in Oromia Region, Ethiopia. One thousand seven hundred twenty-one patients who visited the hospitals for various medical conditions were tested with qRT-PCR and/or Ag-RDTs. Qualitative detection of SARS-CoV-2 antigen was performed using the Panbio™ COVID-19 Ag rapid test device.

Results

Compared with qRT-PCR, Ag-RDTs had a sensitivity of 33.3 % (95%CI: 30.9%-35.9 %) and a specificity of 99.3 % (95%CI: 98.8%-99.7 %) to detect active SARS-CoV-2 infection. The area under the receiver operator curve was 0.67 (95%CI: 0.63-0.69). The sensitivity of Ag-RDTs appeared high in patients with shortness of breath (73.3 %) and those presenting with all three symptoms - fever, cough, and dyspnea (71.4 %). In all instances, specificity was more than 98 %. The Ag-RDT positivity rate also correlated well with viral load: 51.7 % in cases with cycle threshold (Ct) < 25 (high viral load) and only 3.4 % when Ct > 25 (low viral load).

Conclusion

Although Ag-RDT for diagnosing SARS-CoV-2 is a good option as a point-of-care screening tool, it has a low sensitivity to detect active infections. Using Panbio™ COVID-19 Ag Rapid test for diagnostic and treatment decisions may lead to a false negative, resulting in patient misdiagnosis, ultimately contributing to disease spread and poor patient outcome.

Assessment of Availability of Tracer Drugs and Basic Diagnostics at Public Primary Health Care Facilities in Ethiopia During COVID-19 Pandemic

Background

The emergence of COVID-19 pandemic has disrupted the supply chain and stock of medicines and drugs across the globe. Tracer drugs are essential medicines that address the population's priority health problems. Thus, this study aimed to assess availability of tracer drugs and basic diagnostics at public primary health care facilities in Ethiopia.

Methods

Facility based cross-sectional study was employed in four regions and one city administration. The primary health care units (PHCUs) were purposively selected in consultation with respective regional health bureaus. Finally, 16 hospitals, 92 health centers and 344 health posts were included. This study adopted WHO's tool that was being used to rapidly assess the capacity of health facilities to maintain the provision of essential health services during the COVID-19. Descriptive analysis was done using frequency and percentage, and results were presented.

Results

The overall mean availability of tracer drugs in PHCUs was 77.6%. Only 2.8% of PHCUs have all tracer drugs. The mean availability of basic diagnostic at national level was 86.6% in PHUs except health posts where it was less. Health facilities with all basic diagnostic services was 53.7%. Of the total 344 health posts assessed, 71% were providing diagnostic testing for malaria using either laboratory equipment or rapid diagnostic test (RDT) while 43% provide urine test for the pregnancy.

Conclusion

This study shows availability of all tracer drugs in PHCUs in Ethiopia was extremely low. There was regional variation in availability of tracer drugs and basic diagnostics. It is very crucial to increase availability of tracer drugs and diagnostics. Drugs and diagnostic materials should be supplied according to the capacity and location of health facilities.

Effect of COVID-19 pandemic on the incidence of acute diarrheal disease and pneumonia among under 5 children in Ethiopia- A database study

COVID-19 has had a devastating impact on preventable and treatable pediatric diseases in Ethiopia. This study looks at the impact of COVID-19 on pneumonia and acute diarrheal diseases in the country, as well as the differences between administrative regions. In Ethiopia, we conducted a retrospective pre-post study to assess the impact of COVID-19 on children under the age of five who had acute diarrhea and pneumonia and were treated in health facilities during the pre-COVID-19 era (March 2019 to February 2020) and the COVID-19 era (March 2020 to February 2021). From the National Health Management District Health Information System (DHIS2, HMIS), we retrieved data on total acute diarrheal disease and pneumonia, along with their regional and monthly distribution. We calculated incidence rate ratios comparing the rates of acute diarrhea and pneumonia during the pre-and post-COVID-19 eras and adjusted for the year, using Poisson regression. The number of under-five children treated for acute pneumonia decreased from 2,448,882 before COVID-19 to 2,089,542 ((14.7% reduction (95%CI;8.72-21.28), p<0.001)) during COVID-19. Similarly, the number of under-five children treated for acute diarrheal disease decreased from 3,287,850 in pre-COVID-19 to, 2,961,771((9.91% reduction (95%CI;6.3-17.6%),p<0.001)) during COVID-19. In the majority of the administrative regions studied, pneumonia and acute diarrhea diseases decreased during COVID-19, but they increased in Gambella, Somalia, and Afar. During the COVID-19 period, the greatest reduction of children with pneumonia (54%) and diarrhea disease (37.3%) was found in Addis Ababa (p<0.001). The majority of administrative regions included in this study have seen a decrease in pneumonia and acute diarrheal diseases among children under the age of five, while three regions namely, Somalia, Gambela, and Afar saw an increase in cases during the pandemic. This emphasizes the importance of using tailored approaches in mitigating the impact of infectious diseases such as diarrhea and pneumonia during situations of a pandemic such as COVID-19.

COVID-19 Vaccine Hesitancy and Its Associated Factors Among Adolescents

Background

Currently, COVID-19 disease is a major public health issue that affects a large number of people worldwide. The COVID-19 vaccine is one of the best preventative measures. Adolescents between the ages of 12 and 17 are eligible to get the COVID-19 vaccine. The COVID-19 pandemic cannot be stopped if people are reluctant to use this vaccine. However, the extent of COVID-19 vaccine hesitancy and related variables among adolescents are not well understood.

Objectives

To assess the magnitude of COVID-19 vaccine hesitancy and its associated factors among adolescents in Seka Chekorsa town, Jimma, Ethiopia.

Methods

Institutional-based cross-sectional study employing both qualitative and quantitative methods were used. The study participants were selected using a simple random sampling technique. Data were collected using interviewer-administered questions. Data collected was checked for completeness and entered into EPI data version 3.1. Finally, data were exported to SPSS version 25 for further analysis. The bivariate analysis was used to identify variables eligible for multivariate logistic regressions. In a multivariable analysis to identify factors that have statistically significant association, a p value less than 0.05 and a 95% confidence interval were used. The qualitative data were triangulated with quantitative data.

Results

In this study, 379 adolescents were participated, yielding a response rate of 95.2%. The magnitude of COVID-19 vaccine hesitancy among adolescents was 29% (95% CI: 24.3-33.5%). Being female (AOR = 1.89, 95%, 1.81-3.56), primary education (AOR = 2.99, 95% CI: 1.26-3.56), source information from social media (AOR = 2.42, 95% CI: 1.06-5.57), poor knowledge about COVID-19 disease (AOR = 3.18, 95% CI: 1.66-6.12), unfavorable attitude (AOR = 5.2, 95% CI: 2.76-9.79) and poor knowledge towards COVID-19 vaccine (AOR = 5.66, 95% CI, 2.91-11.0) were associated with COVID-19 vaccine hesitancy among adolescents.

Conclusion

This study shows that COVID-19 vaccine hesitancy among adolescents is very high. Being female, poor knowledge towards COVID-19 disease and the vaccine, an unfavorable attitude and social media were factors significantly associated with COVID-19 vaccine hesitancy.

Priority age targets for COVID-19 vaccination in Ethiopia under limited vaccine supply

The worldwide inequitable access to vaccination claims for a re-assessment of policies that could minimize the COVID-19 burden in low-income countries. Nine months after the launch of the national vaccination program in March 2021, only 3.4% of the Ethiopian population received two doses of COVID-19 vaccine. We used a SARS-CoV-2 transmission model to estimate the level of immunity accrued before the launch of vaccination in the Southwest Shewa Zone (SWSZ) and to evaluate the impact of alternative age priority vaccination targets in a context of limited vaccine supply. The model was informed with available epidemiological evidence and detailed contact data collected across different geographical settings (urban, rural, or remote). We found that, during the first year of the pandemic, the mean proportion of critical cases occurred in SWSZ attributable to infectors under 30 years of age would range between 24.9 and 48.0%, depending on the geographical setting. During the Delta wave, the contribution of this age group in causing critical cases was estimated to increase on average to 66.7-70.6%. Our findings suggest that, when considering the vaccine product available at the time (ChAdOx1 nCoV-19; 65% efficacy against infection after 2 doses), prioritizing the elderly for vaccination remained the best strategy to minimize the disease burden caused by Delta, irrespectively of the number of available doses. Vaccination of all individuals aged ≥ 50 years would have averted 40 (95%PI: 18-60), 90 (95%PI: 61-111), and 62 (95%PI: 21-108) critical cases per 100,000 residents in urban, rural, and remote areas, respectively. Vaccination of all individuals aged ≥ 30 years would have averted an average of 86-152 critical cases per 100,000 individuals, depending on the setting considered. Despite infections among children and young adults likely caused 70% of critical cases during the Delta wave in SWSZ, most vulnerable ages should remain a key priority target for vaccination against COVID-19.

Escalating spread of SARS-CoV-2 infection after school reopening among students in hotspot districts of Oromia Region in Ethiopia: Longitudinal study

BACKGROUND

COVID-19 pandemic caused by extended variants of SARS-CoV-2 has infected more than 350 million people, resulting in over 5.5 million deaths globally. However, the actual burden of the pandemic in Africa, particularly among children, remains largely unknown. We aimed to assess the seroepidemiological changes of SARS-CoV-2 infection after school reopening among school children in Oromia, Ethiopia.

METHODS

A prospective cohort study involving students aged 10 years and older were used. A serological survey was performed twice, at school reopening in December 2020 and four months later in April 2021. Participants were selected from 60 schools located in 15 COVID-19 hotspot districts in Oromia Region. Serology tests were performed by Elecsys anti-SARS-CoV-2 nucleocapsid assay. Data were collected using CSentry CSProData Entry 7.2.1 and exported to STATA version 14.2 for data cleaning and analysis.

RESULTS

A total of 1884 students were recruited at baseline, and 1271 completed the follow-up. SARS-CoV-2 seroprevalence almost doubled in four months from 25.7% at baseline to 46.3% in the second round, with a corresponding seroincidence of 1910 per 100,000 person-week. Seroincidence was found to be higher among secondary school students (grade 9-12) compared to primary school students (grade 4-8) (RR = 1.6, 95% CI 1.21-2.22) and among those with large family size (> = 5) than those with a family size of <3 (RR = 2.1, 95% CI 1.09-4.17). The increase in SARS-CoV-2 seroprevalence among the students corresponded with Ethiopia's second wave of the COVID-19 outbreak.

CONCLUSION

SARS-CoV-2 seroprevalence among students in hotspot districts of the Oromia Region was high even at baseline and almost doubled within four months of school recommencement. The high seroincidence coincided with the second wave of the COVID-19 outbreak in Ethiopia, indicating a possible contribution to school opening for the new outbreak wave.

COVID-19 vaccine acceptance in the second wave of the pandemic among university students in Ethiopia: application of the health belief model

Background

The first case of COVID-19 virus was reported in Africa on 14 February 2020. The pandemic became more aggressive in the continent during the second wave than the first wave. Promoting vaccination behavior is an unparalleled measure to curb the spread of the pandemic. Regarding this, the health belief model (HBM) is the major model for understanding health behaviors. This study aimed to examine predictors of intended COVID-19 vaccine acceptance in the second wave of the pandemic among university students in Ethiopia using HBM.

Methods

A cross-sectional study was conducted among 423 randomly selected medical and health science students at the University of Gondar from 21 August to 15 September 2020. Analysis of data was performed using STATA 14.0. Linear regression analysis was applied and a p value of less than 0.05 was used to declare statistical significance.

Results

Among the total participants, 293 [72.2% (95.0%: CI: 67.2-76.8)] of them scored above the mean of COVID-19 vaccine acceptance. HBM explained nearly 46.3% (adjusted R2 = 0.463) variance in intention to receive the COVID-19 vaccine. Year of study (β = 0.288; 95% CI: 0.144-0.056), using social media (β = 0.58; 95% CI: 1.546-2.804), existing chronic disease (β = 0.12; 95% CI: 0.042-0.433), perceived overall health condition (β = 0.117; 95% CI: 0.307-0.091), perceived susceptibility (β = 0.58; 95% CI: 1.546-2.804), perceived benefit (β = 0.338; 95% CI: 1.578-2.863), and cues to action (β = 0.49; 95% CI: 0.388-0.99) were significantly associated with intended COVID-19 vaccine acceptance at p value < 0.5.

Conclusion

Approximately, three-quarters of the participants were above the mean score of COVID-19 vaccine acceptance, which is higher compared to previous reports in resource-limited settings. Interventions in this study setting chould include placing emphasis on the risks of acquiring COVID-19, enhancing perceived benefits of COVID-19 vaccination and improving cues to action by advocating COVID-19 vaccination. Our findings also implied that social media health campaigns are significant factor in COVID-19 vaccination behavioral change in this study setting.

Household Readiness to Care for Mild and Asymptomatic COVID-19 Cases at Home, Southwest Ethiopia: A Community-based Cross-Sectional Study

Background

Corona virus disease (COVID-19) continued with its notorious effects overwhelming health institutions. Thus, home-based identification and care for asymptomatic and mild cases of COVID-19 has been recommended. Therefore, the objective of this study was to assess the level of household readiness for caring asymptomatic and mild cases of COVID-19 at home.

Methods

A community-based cross-sectional study was conducted from March-June 2021 on randomly selected 778 households. Data entry and analysis were carried out using EpiData and SPSS version 25, respectively. Multivariable logistic regression was modeled to identify independent predictors of community readiness.

Results

Overall readiness of the community was very low (43.8%). Factors positively affecting household readiness were male household heads (AOR = 1.6; 95%CI: 1.05, 2.45), primary (AOR=2.0; CI:.62, 1.59) and higher (AOR = 1.90; 95%CI: 1.04, 3.45) educational level of the respondents, number of rooms within household (AOR = 1.22; CI: 1.03, 1.46), having additionally house (AOR = 2.61; CI: 1.35, 5.03), availability of single use eating utensils (AOR = 2.76; 95%CI: 1.66, 4.56), availability of community water supply (AOR = 8.21; 95% CI: 5.02, 13.43), and community participation and engagement (AOR = 2.81; 95% CI: 1.93, 4.08) in accessing transport, water and sanitation.

Conclusions

The community was less prepared in terms of housing, infection prevention, water and sanitation. Considering alternative options including universal coverage of vaccine is important; designed behavioral change communications can enhance community participation and engagement in improving access to transport, water and sanitation to reduce risk of infections.

A Review of COVID-19 Response Challenges in Ethiopia

BACKGROUND

The COVID-19 pandemic has positioned fragile healthcare systems in low-income countries under pressure, leading to critical gaps in service delivery. The pandemic response demands the healthcare system to be resilient and continue provision of healthcare services. This review is aimed at describing the healthcare response challenges during the pandemic in Ethiopia.

METHODOLOGY

Eligible studies dealing with challenges of the healthcare system in response to the COVID-19 pandemic in Ethiopia were included. The six World Health Organization (WHO) healthcare system building blocks were used to categorize healthcare challenges. PubMed ProQuest, databases were searched, and results were summarized using systematic review synthesis.

RESULTS

Financial constraints led to a shortage of mechanical ventilators. Furthermore, the pandemic hindered the capacity to avail full packages of personal protective equipment in health facilities and intensive care capacity. The pandemic also affected the delivery of maternal, child and new-born services, prevention, and treatment of childhood illness, including immunization services.

CONCLUSIONS

The COVID-19 pandemic posed various challenges to the performance of the healthcare system in Ethiopia. It is recommended that policy makers and stakeholders enhance pandemic preparedness and strengthen response capacity by considering the six WHO healthcare system building blocks.

COVID-19 Case Fatality Rate and Factors Contributing to Mortality in Ethiopia: A Systematic Review of Current Evidence

Background

The ongoing novel coronavirus disease 2019 (COVID-19) is triggering significant morbidity and mortality due to its contagious nature and absence of definitive management. In Ethiopia, despite a number of primary studies have been conducted to estimate the case fatality rate (CFR) of COVID-19, no review study has attempted to summarize the findings to better understand the nature of pandemics and the virulence of the disease.

Objective

To summarize the CFR of COVID-19 and factors contributing to mortality in Ethiopia.

Methods

PRISMA guideline was followed. PubMed, Science Direct, CINAHL, SCOPUS, Hinari, and Google Scholar were systematically searched using pre-specified keywords. Observational studies ie, cohort, cross-sectional, and case-control studies were included. The Newcastle-Ottawa scale adapted for observational studies was used to assess the quality of included studies. CFR was defined as the proportion of COVID-19 cases with the outcome of death within a given period. Factors contributing to COVID-19 mortality at p-value <0.05 were described narratively from the eligible articles.

Results

A total of 13 observational studies were included in this study. Consequently, this review confirmed the CFR of COVID-19 in Ethiopia ranges between 1–20%. Additionally, comorbid conditions, older age group, male sex, substance use, clinical manifestations (abnormal oxygen saturation level, atypical lymphocyte count, fever, and shortness of breath), disease severity, and history of surgery/trauma increased the likelihood of death from COVID-19 death.

Conclusion

This study shows that the range of CFR of COVID-19 in Ethiopia is almost equivalent to other countries, despite the country’s low testing capacity and case detection rate in reference to its total population. Comorbid diseases, older age group, male sex, cigarette smoking, alcohol drinking, clinical manifestations and disease severity, and history of surgery/trauma were factors contributing to COVID-19 mortality in Ethiopia. Therefore, given the alarming global situation and rapidly evolving large-scale pandemics, urgent interdisciplinary interventions should be implemented in those vulnerable groups to lessen the risk of mortality. Furthermore, the CFR of COVID-19 should be estimated from all treatment and rehabilitation centers in the country, as underestimation could be linked to a lack of preparedness and mitigation. A large set of prospective studies are also compulsory to better understand the CFR of COVID-19 in Ethiopia.

COVID-19 precautionary practices and associated factors among clients visiting a tertiary hospital, Addis Ababa, Ethiopia

Background

Despite efforts to contain the spread of COVID-19, Addis Ababa, the country’s COVID-19 epicenter, is experiencing a sharp increase in the number of cases and death rate. While poor public adherence to COVID-19 precautionary practices is evident, factors associated with it are not well studied. We aimed to assess the level of practice of COVID-19 precaution and associated factors.

Methods

This was a hospital-based cross-sectional study conducted from February 1^st to 15^th, 2021 at Saint Paul’s Hospital Millennium Medical College, a tertiary teaching hospital in Addis Ababa, Ethiopia. We used a structured questionnaire to conduct a face-to-face exit interview with clients visiting the hospital. Systematic random sampling was employed to recruit study participants. Binary and multivariable logistic regressions were implemented to examine factors associated with precautionary practices. Statistical significance was declared at p-value <0.05. The Crude odds ratio (COR) and Adjusted odds ratio (AOR) were reported with a 95% confidence interval.

Results

We analyzed data obtained from 262 participants. The mean age of participants was 36 (SD+12) years. The majority (207, 79%) of the study participants had a favorable attitude towards prevention and control measures of COVID-19. A little over half (116, 55.7%) of the respondents had a satisfactory level of practice of COVID-19 precautions. Living in an area with strict enforcement of COVID-19 precautionary measures [AOR: 2.25, 95% CI (1.22–4.15)], and having a favorable attitude of COVID-19 prevention [AOR: 4.88, 95% CI (2.08–11.68)] were significantly associated with satisfactory COVID-19 precautionary practices.

Conclusions

The level of practice of COVID-19 precaution was unsatisfactory. Favorable attitude and stricter enforcement of COVID-19 preventive measures might have contributed more to adherence to precautionary practices. The findings highlight the need for a public health education strategy targeted at improving attitudes of the community on COVID-19 focusing on the effectiveness of preventive measures.

Prevalence of COVID-19 in West Gondar Zone, Northwest Ethiopia: A Population-Based Retrospective Study

OBJECTIVE

Coronavirus disease 2019 (COVID-19) has spread rapidly around the world, affecting every community directly or indirectly. Therefore, this study aims to investigate the prevalence of COVID-19 infection in the population of the West Gondar zone.

METHOD

A retrospective cross-sectional study was conducted from November 2020 to January 2021, in the West Gondar zone, Northwest Ethiopia. Records of study participants with required information like age, gender, travel history, type of specimen taken, and site of specimen taken were included. For analysis, the statistical package for social sciences (SPSS) version 20 software was used. Descriptive statistics were summarized as percentages and means ± standard deviation. The chi-squared test is used to compare categorical data.

RESULTS

A total of 1,166 participants were enrolled in this study. Of them, 16 individuals had positive results, giving a prevalence of 1.37% (95% CI: 0.66-2.08). Living in an urban area (P-value = 0.035) and being female (P-value = 0.045) was statistically associated with the positive rate for COVID-19.

CONCLUSIONS

This study revealed a low prevalence of COVID-19 infection in the study area despite the increasing and rapid dissemination of the disease. State-wide population prevalence study should be done to estimate the general prevalence of COVID-19 in Ethiopia.

Tracer Pharmaceuticals Availability and Distribution Trends Prior to and During the Covid-19 Pandemic: A Comparative Study

Background

Coronavirus disease 2019 (Covid-19) has had an unprecedented impact on the health products delivery system. To maintain routine health services, tracer pharmaceuticals (TPs) should always be available and accessible in healthcare institutions. Thus, this study aimed to explore the influence of the Covid-19 on TPs availability and distribution trends in the context of the Covid-19 pandemic in Ethiopia.

Methods

An institution-based comparative study was undertaken on 25 TPs in the pharmaceutical supply agency. From the agency’s logistical data, we collated the amount of TPs ordered, received, and distributed, as well as the stock status, by using an observation checklist. The collated data were recorded in Microsoft Excel and transferred to SPSS for analysis. A frequency and percentage analysis were performed to evaluate the fill rate, product availability, and stock-out duration. A dependent t-test was used to compare if there was a significant mean difference in TPs distribution before and after the Covid-19 at a p-value less than 5%.

Results

Before Covid-19, 18 (72%) of the TPs were refilled above 80% of amount ordered. After the pandemic, however, the fill rate dropped to 48%. The availability of TPs during the Covid-19 was 60%. During the six months of Covid-19, the average stock-out duration for all TPs was 34.68 days, with Cimetidine 200mg/mL injectable (line-item fill rate = 0, days out of stock = 180 days) being the most stocked-out item. Tracer pharmaceuticals distribution before Covid-19 (M = 81,317, SD = 139,274) were significantly different after the pandemic (M = 60,212, SD = 94,966) at the 5% significance level (t (24) = 2.289, p = 0.031).

Conclusion

This survey reveals how Covid-19 has influenced service providers’ logistics systems. Following the pandemic, the line fill rate fell below half with a three-fifths availability of products. To effectively manage supply chain disruptions experienced in Covid-19 and beyond, the agency in collaboration with stakeholders should make an effort to enhance end-to-end inventory visibility, establish a resilient logistics system, strengthen domestic manufacturers’ capabilities, and develop contingency plans with supplying partners.

Seroepidemiology and model-based prediction of SARS-CoV-2 in Ethiopia: longitudinal cohort study among front-line hospital workers and communities

Background

Over 1 year since the first reported case, the true COVID-19 burden in Ethiopia remains unknown due to insufficient surveillance. We aimed to investigate the seroepidemiology of SARS-CoV-2 among front-line hospital workers and communities in Ethiopia.

Methods

We did a population-based, longitudinal cohort study at two tertiary teaching hospitals involving hospital workers, rural residents, and urban communities in Jimma and Addis Ababa. Hospital workers were recruited at both hospitals, and community participants were recruited by convenience sampling including urban metropolitan settings, urban and semi-urban settings, and rural communities. Participants were eligible if they were aged 18 years or older, had provided written informed consent, and were willing to provide blood samples by venepuncture. Only one participant per household was recruited. Serology was done with Elecsys anti-SARS-CoV-2 anti-nucleocapsid assay in three consecutive rounds, with a mean interval of 6 weeks between tests, to obtain seroprevalence and incidence estimates within the cohorts.

Findings

Between Aug 5, 2020, and April 10, 2021, we did three survey rounds with a total of 1104 hospital workers and 1229 community residents participating. SARS-CoV-2 seroprevalence among hospital workers increased strongly during the study period: in Addis Ababa, it increased from 10·9% (95% credible interval [CrI] 8·3–13·8) in August, 2020, to 53·7% (44·8–62·5) in February, 2021, with an incidence rate of 2223 per 100 000 person-weeks (95% CI 1785–2696); in Jimma Town, it increased from 30·8% (95% CrI 26·9–34·8) in November, 2020, to 56·1% (51·1–61·1) in February, 2021, with an incidence rate of 3810 per 100 000 person-weeks (95% CI 3149–4540). Among urban communities, an almost 40% increase in seroprevalence was observed in early 2021, with incidence rates of 1622 per 100 000 person-weeks (1004–2429) in Jimma Town and 4646 per 100 000 person-weeks (2797–7255) in Addis Ababa. Seroprevalence in rural communities increased from 18·0% (95% CrI 13·5–23·2) in November, 2020, to 31·0% (22·3–40·3) in March, 2021.

Interpretation

SARS-CoV-2 spread in Ethiopia has been highly dynamic among hospital worker and urban communities. We can speculate that the greatest wave of SARS-CoV-2 infections is currently evolving in rural Ethiopia, and thus requires focused attention regarding health-care burden and disease prevention.

Social distancing and preventive practices of government employees in response to COVID-19 in Ethiopia

Public health and social interventions are critical to mitigate the spread of the coronavirus disease 2019 (COVID-19) pandemic. Ethiopia has implemented a variety of public health and social measures to control the pandemic. This study aimed to assess social distancing and public health preventive practices of government employees in response to COVID-19. A cross-sectional study was conducted among 1,573 government employees selected from 46 public institutions located in Addis Ababa. Data were collected from 8th to 19th June 2020 using a paper-based self-administered questionnaire and analyzed using SPSS version 23.0. Descriptive statistics were used to summarize the data. Binary logistic regression analyses were used to identify factors associated with outcome variables (perceived effectiveness of facemask wearing to prevent coronavirus infection, and COVID-19 testing). Majority of the participants reported facemask wearing (96%), avoiding close contact with people including handshaking (94.8%), consistently followed government recommendations (95.6%), frequent handwashing (94.5%), practiced physical distancing (89.5%), avoided mass gatherings and crowded places (88.1%), restricting movement and travelling (71.8%), and stayed home (35.6%). More than 80% of the participants perceived that consistently wearing a facemask is highly effective in preventing coronavirus infection. Respondents from Oromia perceived less about the effectiveness of wearing facemask in preventing coronavirus infection (adjusted OR = 0.27, 95% CI:0.17-0.45). About 19% of the respondents reported that they had ever tested for COVID-19. Respondents between 40-49 years old (adjusted OR = 0.41, 95% CI:0.22-0.76) and 50-66 years (adjusted OR = 0.43, 95% CI:0.19-0.95) were less likely tested for coronavirus than the younger age groups. Similarly, respondents from Oromia were less likely to test for coronavirus (adjusted OR = 0.26, 95% CI:0.12-0.56) than those from national level. Participants who were sure about the availability of COVID-19 testing were more likely to test for coronavirus. About 57% of the respondents perceived that the policy measures in response to the pandemic were inadequate. The findings showed higher social distancing and preventive practices among the government employees in response to COVID-19. Rules and regulations imposed by the government should be enforced and people should properly apply wearing facemasks, frequent handwashing, social and physical distancing measures as a comprehensive package of COVID-19 prevention and control strategies.
