The knowledge, attitude and practice of community people on dengue fever in Central Nepal: a cross-sectional study

Knowledge, attitudes, and practices regarding dengue and its vectors among medical professionals: a cross-sectional study

Dengue fever remains a significant global public health issue, necessitating a collaborative One Health strategy for efficient management. This cross-sectional study evaluated the knowledge, attitudes, and practices (KAP) of 516 healthcare professionals regarding dengue and its vectors. Most participants were young (82.6%), male (75.6%), and had MBBS qualifications (61.4%), predominantly employed in hospital settings (70.3%), and living in non-hotspot areas (53.3%). The research indicated that 65.1% of respondents possessed moderate knowledge about dengue, while 19.6% exhibited high knowledge and 15.3% showed low knowledge. Most participants (87.8%) correctly identified Aedes mosquitoes as the main vector, with 52.7% recognizing stagnant clean water as their breeding habitat. Positive attitudes were noted among 72.5% of participants; 51% viewed dengue as a moderately serious threat, and 47.3% strongly agreed on the crucial role of healthcare professionals in prevention. Conversely, 48.9% pointed out insufficient preventive measures in their facilities. In terms of practices, 80.8% of participants regularly informed patients about prevention, and 79.1% recommended CBC tests for suspected cases. Protective measures such as repellents and mosquito nets were consistently utilized by 57.2%, whereas 41.1% reported infrequent use. Remarkably, 59.7% had never undergone formal training on dengue prevention and management, with only 23.6% receiving consistent training. Furthermore, while 50.8% indicated that their facilities had adequate resources for dengue treatment, 42.8% reported a lack of mosquito control activities. These findings underline significant gaps in training, resource availability, and preventive practices, highlighting the urgent need for enhanced capacity-building, resource allocation, and intersectoral collaboration within the One Health framework to combat the effects of dengue in the region.

On people's perceptions of climate change and its impacts in a hotspot of global warming

The Hindu Kush Himalayan region is a global hotspot for climate change and highly vulnerable to its direct and indirect impacts. Understanding people's perception of climate change is crucial for effective adaptation strategies. We conducted a study by using quantitative (Household survey, n = 660) and qualitative data collection tools (Focus group discussion, n = 12; In-depth interviews, n = 27) in central Nepal encompassing three altitudinal regions: Lowland (<1000 m amsl; Terai region), Midland (1000-1500 m amsl; hilly region) and Highland (1500-2100 m amsl; mountainous region). We analyzed 37 years (1981-2017) of climatic data from respective districts (Lowland: Chitwan, Dhading; Midland: Kathmandu, Lalitpur; Highland: Nuwakot, Rasuwa). People's perception was compared with climate extreme indices measured along these regions and evaluated if they accurately recognized the impacts on the environment and human health. Our findings show significant climate changes, including rising summer temperature, region-specific winter temperatures and extended monsoon seasons in Nepal. Participants in our study accurately perceived these trends but misperceived heavy precipitation patterns. Reported impacts are rise in crop diseases, human diseases, vector expansion and climate induced disasters like floods, landslides, and water resource depletion, with perception accuracy varying by region. These insights highlight the importance of understanding regional and cross-regional perceptions in relation to climate data in order to develop tailored climate adaptation strategies. Policymakers can use this information to establish region-specific educational and communication initiatives, addressing communities' distinctive vulnerabilities and needs across diverse landscapes. Such approaches can enhance equitable and effective climate resilience in subtropical to alpine regions.

Knowledge, attitude, and practice of stroke patients' family members towards stroke rehabilitation: A cross-sectional study

BACKGROUND

This study aimed to explore the knowledge, attitude, and practice (KAP) among family members of stroke patients regarding stroke rehabilitation.

METHODS

A cross-sectional study was conducted on the family members of stroke patients at the China Rehabilitation Research Center from February 15 to May 2, 2024. This study collected demographic data and KAP scores through a self-designed questionnaire.

RESULTS

The study enrolled 517 family members, of which 344 (66.54%) were male. The mean scores for knowledge, attitude, and practice were 12.01 ± 5.46 (possible range: 0-20), 49.40 ± 4.96 (possible range: 11-55), and 41.93 ± 7.49 (possible range: 10-50), respectively. Correlation analyses demonstrated a significant positive relationship between knowledge and attitude (r = 0.501, P < 0.001), knowledge and practice (r = 0.471, P < 0.001), and attitude and practice (r = 0.441, P < 0.001). Structural Equation Modeling indicated that showed that knowledge directly affected attitude (β = 0.481, P = 0.004) and practice (β = 0.351, P = 0.009), and attitude directly affected practice (β = 0.244, P = 0.007). Additionally, knowledge indirectly affected practice through attitude (β = 0.117, P = 0.006).

CONCLUSIONS

This study identified significant gaps in knowledge, despite generally positive attitudes and proactive practices among family members of stroke patients regarding stroke rehabilitation. This highlights the necessity for tailored educational programs for family members to address these knowledge gaps.

Knowledge, attitude, and practices of the community about Chikungunya in selected Districts of Afar Region, Northeast Ethiopia; its implications for controlling the disease: a community-based quantitative and qualitative cross-sectional study

BACKGROUND

Chikungunya (CHIK) is a viral disease spread by Aedes mosquitoes in tropical and subtropical countries, including Ethiopia. It is important to educate communities and implement behavioral and social interventions to prevent and control the spread of disease. This study assessed the community's knowledge, attitude, and practices (KAP) about CHIK disease in the Afar Region, Northeast Ethiopia.

METHODS

A community-based quantitative and qualitative cross-sectional study was conducted between September 2022 and January 2023 in two districts in the Afar Region, Ethiopia. A household survey (HHS) using a structured questionnaire was conducted through face-to-face interviews for the quantitative study. For the qualitative research, focus group discussions (FGDs) were conducted using a semi-structured questionnaire. Data was analyzed using descriptive statistics, Pearson's correlation coefficient, and multiple linear regressions.

RESULTS

The study included 296 and 116 adult community members for quantitative and qualitative studies, respectively. Of 296 respondents, 67.3% had previously heard of CHIK, and of those who heard of it, 44.7% knew that CHIK is caused by a virus. While a majority (68.8%) of participants believed that CHIK could be prevented, only 45.6% considered it a serious illness. Additionally, over half (56.8%) of the respondents knew that not all mosquitoes transmit CHIK. About 48.7% were able to identify the Aedes mosquito, but only 16.5% of those knew that Aedes mosquitoes bite during the daytime. The overall mean correct/positive response scores for knowledge, attitudes, and practices were 63.2%, 60.0%, and 60.0%, respectively. Being a student and having educational levels of grade 9-12th and college or above were associated with good knowledge while being single, having an educational level of 9-12th, and being within the age group of 45-59 years old were found to be associated with positive attitude scores.

CONCLUSION

The study revealed a limited understanding of CHIK and the role of the Aedes mosquito in the study area. The community had uncertainty about the disease, its transmission, and prevention measures. The lack of understanding may affect attitudes towards the disease and risk perceptions, leading to less practice in prevention and control measures. The findings suggest the need for community-based educational initiatives to improve awareness and promote prevention and control measures.

A mixed method evaluation of knowledge, attitude and practice on dengue fever among Lalitpur Metropolitan City residents: a cross-sectional investigation

BACKGROUND

Dengue poses a significant global public health challenge, including in Nepal. Understanding community's knowledge, attitudes, and behaviors concerning dengue fever is imperative to developing effective prevention and control strategies. This study aimed to assess the knowledge, attitude, and practices related to dengue fever among residents of Lalitpur Metropolitan City.

METHODS

A descriptive cross-sectional household study was conducted using a mixed-method approach, which included quantitatively studying 636 individuals and conducting 20 qualitative interviews. The data was collected between April 2023 and June 2023. The multistage cluster sampling method was applied for household selection during the quantitative study and a purposive judgmental sampling method was used to identify participants for the qualitative interviews. Face-to-face interviews were conducted using a structured questionnaire for the quantitative study and an interview guide for the qualitative study. Quantitative data were analysed using logistic regression in STATA version 13, and thematic analysis was applied to the qualitative data. The findings were validated through triangulation of results from both the qualitative and quantitative study.

RESULTS

Regarding knowledge, 64.94% (n = 413/636) reported being informed about dengue fever. In terms of attitude, a substantial majority, 91.51% (n = 582/636), expressed a positive attitudes toward dengue fever, indicating a favorable perception and knowledge of its significance. Concerning practice, 49.84% (n = 317/636) of respondents reported actively engaging in dengue fever prevention measures. The variables gender, previous history of dengue fever and residency were the determinants of dengue fever knowledge. Additionally, gender, residency, and attitude were predictors of preventive practices concerning dengue fever.

CONCLUSION

Our study revealed that while the community demonstrated good knowledge of dengue fever and positive attitudes toward prevention, their preventive practices were inconsistent, indicating a gap between knowledge and action. A positive attitude was linked to better adherence to preventive measures. To address this gap, it is crucial to promote a positive attitude toward dengue prevention through initiatives like education efforts and social mobilization programs. Implementing Social and Behavior Change Communication (SBCC) programs focused on dengue prevention and control measures can help bridge this knowledge-action gap.

Investigating public understanding and actions regarding Aedes mosquitoes and dengue prevention across altitudinal range in central Nepal

BACKGROUNDS OBJECTIVES

Dengue fever, transmitted by Aedes mosquitoes, is a significant public health concern in Nepal. An extensive Knowledge, Attitude, and Practice (KAP) survey related to Aedes mosquitoes and prevention of dengue was conducted along the route from Matihani (62 m above sea level) to Kalinchok (3840 m asl) in central Nepal. This research examined residents' awareness of Aedes mosquitoes and the diseases they transmit, aiming to support the World Health Organization's national and global fight against mosquito-borne diseases.

METHODS

The survey included 550 participants aged 18-75 years (249 males and 201 females). Door-to-door campaigns were conducted to gather data on knowledge scores, practices, and attitudes about Aedes mosquitoes using a standard structured questionnaire.

RESULTS

Findings of this study revealed a moderate level of knowledge across the study area, with a mean knowledge score of 5.525±2.58 (correct answer rate of 46.05%). While 99.6% of respondents were aware of dengue transmission by mosquitoes, only 64.5% were able to report Aedes mosquitoes as the key transmitter. Less than one-third of the participants (27.8%) were familiar with black-and-white stripes in Aedes. Additionally, only 36.7% were knowledgeable about the day-biting behavior of Aedes mosquitoes.

INTERPRETATION CONCLUSION

This KAP survey provides valuable insights into community understanding of Aedes mosquitoes and dengue prevention practices associated with various Nepalese communities residing in low to high altitudes of central Nepal. These findings can be adopted to address the increasing health burden faced by countries with low-to-high altitude regions within the Hindu Kush Himalayas.

Uncovering the knowledge gap: A web-based survey of healthcare providers' understanding and management of dengue fever in East Azerbaijan, Iran

BACKGROUND

Dengue fever (DF) is increasingly recognized as one of the world's major mosquito-borne diseases and causes significant morbidity and mortality in tropical and subtropical countries. Appropriate and timely diagnosis and risk stratification for severe disease are crucial in the appropriate management of this illness. Healthcare providers (HCPs) play a key role in dengue fever diagnosis, management and prevention. The present study was conducted to determine the knowledge, attitudes and practices (KAP) among HCPs in East Azerbaijan Province, Iran.

METHODS

A cross-sectional survey among 948 HCPs, using a structured questionnaire, was conducted in East Azerbaijan Province from May to July 2022. Data analysis was undertaken using descriptive methods, the Chi-square test or Fisher's exact test, and logistic regression. A P-value <0.05 was considered for statistical significance.

RESULTS

Out of the 948 (68.5% female) respondents, 227 were physicians and 721 were health professionals. The knowledge level of DF was found to be largely inadequate in the present study population (80.4%). The physician vs. health professional were a significant factor in differentiating attitude scores. The mean practice score regarding DF prevention and control measures among respondents was 8.40±1.97.

CONCLUSION

The findings call for urgent continuous education and training courses to increase KAP levels and increased capacity and capability for DF prevention and control. This is of outmost importance for the first point of care of DF patients.

Exploring community needs in combating aedes mosquitoes and dengue fever: a study with urban community in the recurrent hotspot area

BACKGROUND

Aedes mosquitoes are the main vector of dengue infection, a global health threat affecting millions of people annually. Conventional prevention and control methods against dengue outbreaks have only achieved marginal success. Recognizing the complex issue at hand, a multilevel participatory approach is crucial. Thus, alternative strategies that involve community engagement are increasingly being considered and attempted. While community-based vector control programs have been conducted, sustaining behavioral changes among the population remains a challenge. This study aimed to identify the specific community needs in combating Aedes mosquitoes and dengue fever as a basis to guide the development of community-driven initiatives and foster a deeper sense of ownership in the fight against dengue.

METHODS

Between 1 August 2022 and 30 November 2022, we conducted a study in Hulu Langat district, Selangor, using a mixed-method design. All participants consented to the study, which comprised 27 participants (FGDs) and 15 participants (IDIs). The IDIs included two participants with a history of dengue fever, one community leader, one faith leader, seven local authorities, and four district health officers. Semi-structured interviews and discussions were performed among stakeholders and community members recruited via purposive and snowball sampling techniques. All interviews were audio-recorded before being analyzed using reflexive thematic analysis.

RESULTS

These results derived from qualitative data explored the perspectives and needs of communities in combating Aedes mosquitoes and dengue fever. Interviews were conducted with various stakeholders, including community members, leaders, and health officers. The study identified the necessity of decisive actions by authorities to address the impact of the dengue epidemic, the importance of community engagement through partnerships and participatory approaches, the potential benefits of incentives and rewards to enhance community participation, and the need for sustained community engagement and education, especially via the involvement of young people in prevention efforts. These findings provide valuable insights into the design of effective strategies against Aedes mosquitoes and dengue fever.

CONCLUSIONS

In short, there is an urgent need for a comprehensive approach involving multiple stakeholders in the fight against Aedes mosquitoes and dengue fever. The approach should incorporate efforts to raise awareness, provide practical resources, and foster community responsibility. The active involvement of teenagers as volunteers can contribute to long-term prevention efforts. Collaboration, resource allocation, and community engagement are crucial for effective dengue control and a healthier environment.

Feasibility of NepaDengue mobile application for dengue prevention and control: user and stakeholder perspectives in Nepal

Background

Dengue has emerged as a significant public health issue in Nepal since 2006, necessitating innovative approaches to disseminating timely information and promoting preventive behaviour. Our study focuses on developing and pretesting a mobile health app called NepaDengue, assessing its acceptance and factors influencing its implementation.

Methods

A concurrent triangulation mixed-method design was used, and an intervention was conducted among 228 university students using the mobile application. Acceptability was assessed using the technology acceptance model (TAM) based on user experiences over 1 week. Focus group discussions among students and female community health volunteers and key informant interviews among key dengue stakeholders were conducted to explore facilitators and barriers. Descriptive statistics were calculated, and a thematic analysis was conducted.

Results

The high acceptability mean rating scores reported based on the TAM construct indicate that the application is perceived as useful and easy to use and exhibits good functioning and gestural design. The use of the NepaDengue application for dengue prevention and control activities has been perceived as acceptable by users and stakeholders. However, specific barriers were identified, including concerns about sustained usability, illiteracy and limited access to the internet and smartphones. We suggested promoting the application, fostering government ownership and encouraging collaboration to enhance its reach and effective implementation.

Conclusions

The NepaDengue application has been perceived as a promising tool for dengue prevention and control in Nepal. Further piloting and implementation of the app in the community setting is recommended.

Knowledge, attitude, and practice regarding dengue among non-health undergraduate students of Nepal

Dengue poses a significant public health concern worldwide. It is identified as a recent emerging infectious disease in Nepal. Understanding the situation and dynamics between knowledge, attitudes, and practices (KAP) related to dengue among students is crucial for effective prevention and control strategies. This study aimed to assess the KAP and their associated factors of dengue among non-health undergraduate students of Nepal to identify gaps and suggest appropriate interventions. A web-based cross-sectional study was conducted among 429 non-health undergraduate students at eleven Nepalese Universities, with 80% of participants from the four most prominent ones in the country. Self-administered online forms were administered via Google Forms platform predominantly through social media for data collection. Data was cleaned and then exported to IBM SPSS Statistics 20.0 for analysis. Demographic characteristics of respondents were described using descriptive statistics. Multivariate logistic regression was conducted to determine the association between individual characteristics and KAP. Pearson's correlation coefficient was used to determine the association between knowledge-attitude, attitude-practice, and knowledge-practice. Statistical significance was determined at the P-value < 0.05. Around half of the participants were female (50.3%). The majority of participants were between 22 to 37 years, unmarried, and belonged to the Brahmin/Chhetri ethnic group. This study demonstrated a significant gap in KAP. Only 15.2% of participants had good knowledge while 25.9% and 68.3% of participants exhibited good attitudes and practices respectively. Marital status (AOR = 3.32, CI: 1.32-8.34), third-year educational level (AOR = 3.59, CI:1.34-9.57), and fourth-year educational level (AOR = 4.93, CI:1.88-12.94) were significantly associated with knowledge regarding dengue. Age (AOR = 1.73, CI: 1.10-3.01) was significantly associated with preventive practice regarding dengue. None of the demographic or socio-economic characteristics of respondents was associated with attitude on dengue. The knowledge-attitude (rka = 0.01), knowledge-practice (rkp = 0.22), and attitude-practice (rap = 0.01) were positively correlated in this study.

Knowledge, Attitudes, and Practices Regarding Dengue Prevention Among Health Volunteers in an Urban Area - Malang, Indonesia

OBJECTIVES

The dengue prevention program known as "One House One Mosquito Larva Inspector" involves health volunteers who play a crucial role in the surveillance of mosquito larvae and reporting their findings to local public health officials. This study aimed to identify factors related to the knowledge, attitudes, and practices (KAP) of dengue prevention behavior among these health volunteers.

METHODS

A study was conducted in 5 sub-districts in Malang, an urban area in Indonesia. We employed a cross-sectional design and utilized a semi-structured questionnaire to assess the KAP of 400 health volunteers. Data were collected through face-to-face interviews.

RESULTS

Multiple logistic regression analysis revealed that individuals with a more positive attitude (odds ratio [OR], 1.69; p<0.05) and those with family sizes greater than five persons (OR, 1.90; p<0.05) were more likely to engage in effective dengue prevention practices. Additionally, possesing good knowledge was significantly assocated with more positive attitude (OR, 2.24; p<0.001). Furthermore, 40% reduction in positive attitude was observed in those over 45 years (OR, 0.60; p<0.05). The best practices most frequently reported by the majority of respondents included always reporting their surveillance activities (75.8%) and cleaning the water container in the bathroom at least once a week (65.2%). However, only 52.2% of respondents regularly checked for mosquito larvae in their neighborhood.

CONCLUSIONS

Sustainable promotion and training for the "One House One Mosquito Larva Inspector" initiative are necessary, particularly among young health volunteers, to improve dengue prevention behaviors both within their own homes and in the surrounding environment.

Attitude towards dengue control efforts with the potential of digital technology during COVID-19: partial least squares-structural equation modeling

Background: Dengue fever is still a public health issue in Indonesia, and during the coronavirus disease 2019 (COVID-19) pandemic, integrated digital technology will be required for its control. This study aims to identify critical indicators influencing attitudes towards dengue control related to the potential for implementing digital technology. Methods: This was a cross-sectional survey, with 515 people willing to fill out an online questionnaire. The analysis was conducted using Partial Least Square-Structural Equation Modelling (PLS-SEM). There were 46 indicators used to assess attitudes toward dengue control, which were organized into six variables: the need for digital information systems, perceptions of being threatened with dengue, the benefits of dengue control programs, program constraints, environmental factors and attitudes in dengue control. Results:  The source of information needed for dengue control was mainly through social media. There was a positive relationship between perception of environmental factors to perception of dengue threat, perception of program constraints, perception of program benefits, and perception of digital technology needs. Perception of program benefits and threatened perception of dengue have a positive relationship with perception of digital technology needs. Conclusions: This model showed the variables perception of digital technology and perception of benefits had a positive association with attitude towards dengue control.

Sociodemographic factors associated to knowledge and attitudes towards dengue prevention among the Peruvian population: findings from a national survey

OBJECTIVES

To evaluate the frequency of knowledge and attitudes towards dengue prevention among the Peruvian population, as well as the sociodemographic factors associated with reported knowledge and attitude outcomes.

DESIGN/SETTING

A cross-sectional study was conducted, based on information from the National Survey of Budget Programs of Peru, 2019.

PARTICIPANTS

We included 57 829 respondents with a mean age of 40.3±17.4 years, of whom 52.8% were women and 87.6% were from urban areas.

PRIMARY AND SECONDARY OUTCOMES

Knowledge about dengue infection (transmission, symptoms, importance of going to a health centre and not self-medicating) and preventive attitudes to avoid infection.

RESULTS

Of all the respondents, 36.2% (n=23 247) presented good knowledge about dengue and 11.6% (n=7890) had a higher number of preventive attitudes (≥3 attitudes). In the multivariate regression analysis, we found that being female (for knowledge: aPR (adjusted prevalence ratio): 1.03; 95% CI 1.02 to 1.03; and for attitude: aPR: 1.02; 95% CI 1.01 to 1.02), being married/cohabiting (for knowledge: aPR: 1.02; 95% CI 1.00 to 1.03; and for attitude: aPR: 1.01; 95% CI 1.00 to 1.02) and residing in the jungle (for knowledge: aPR: 1.14; 95% CI 1.12 to 1.16; and for attitude: aPR: 1.09; 95% CI 1.07 to 1.11) were associated with better knowledge and more preventive attitudes. In addition, we found that being an adolescent (for knowledge: aPR: 0.97; 95% CI 0.96 to 0.99; and for attitude: aPR: 0.99; 95% CI 0.97 to 0.99), and belonging to the Quechua ethnic group (for knowledge: aPR: 0.93; 95% CI 0.91 to 0.94; and for attitude: aPR: 0.98; 95% CI 0.97 to 0.99) were associated with a lower proportion of adequate knowledge and fewer preventive attitudes.

CONCLUSIONS

Our study found a high proportion of poor knowledge and few preventive attitudes towards dengue in the Peruvian population. That highlights the requirement to implement national strategies to educate people about dengue and promote preventive attitudes, considering the factors found.

Knowledge, attitudes, and practices towards mosquito control and used vehicle tire dumping by median household income, in metropolitan New Orleans, Louisiana

Background

Discarded vehicle tires are an important artificial habitat for the larvae of many container-breeding mosquito species worldwide, including in the United States. Unmanaged discarded vehicle tires create health, environmental and social costs, and with budget and staffing constraints, effective management of discarded used vehicle tires a mosquito larval habitat depends in part on the knowledge, attitude, and practices (KAP) of community residents.

Objectives

This study aims to examine the knowledge, attitude and practices of New Orleans, Louisiana residents toward illegally discarded vehicle tires, and larval mosquito control.

Methods

A descriptive cross-sectional design study was used where 422 households were selected using a two-stage cluster random sampling procedure in New Orleans, Louisiana. Heads of households or a person aged 18 years or older self-administered the survey. The questionnaire comprised five parts: screening, tire sightings, preferred communication method, knowledge, attitude and precautionary measures against mosquito control, disease risk and illegal discarding. We then statistically compared above and below median income household responses to identify likely causes of detected differences. The data were analyzed using ordinal regression models via IBM SPSS statistics V.26.0. Statistical significance was set at p < 0.05.

Results

Out of 290 responding households, 95.5% strongly agree or agree that mosquitoes can spread serious diseases like West Nile, Zika or Dengue. Only 2.3% of the sample had high knowledge of illegally discarded tires dumping and mosquito larval control. Those employed were 1.0 times more likely to possess good knowledge than the unemployed (p < 0.001). Despite low knowledge levels regarding mosquito breeding and polluted water in discarded tires, 29.9% of respondents had positive attitude and 20.5% reported sufficient practices. Among the socio-demographic variables, only home ownership and being employed were predictors of knowledge and attitude towards mosquito breeding in illegally discarded tires (p < 0.05).

Conclusions

Despite the observed increasing number of illegally discarded vehicle tires in New Orleans, the knowledge of people about illegal tire dumping and their associated risk factors as suitable larval habitants was low. Therefore, there is a need for developing community-based and place-based tailored sensitization campaigns to prevent illegal used tire dumping, and larval control.
