Risk factors associated with scabies infestation among primary schoolchildren in a low socio-economic area in southeast of Iran

Prevalence and risk factors of scabies among children living in Madrasahs (Islamic religious boarding schools) of Bangladesh: a cross-sectional study

INTRODUCTION

To determine the prevalence and associated factors of scabies among the children living in the Madrasahs (Islamic religious educational institution) of Bangladesh was the objective of the study.

METHODS

This cross-sectional study was conducted in eight selected Madrasahs from May to October 2023 among male and female children aged between 3 and 18 years. Children were screened for scabies according to criteria developed by the International Alliance for the Control of Scabies.

RESULTS

It was found that overall prevalence of scabies among the children living in Madrasahs was almost 34% (mild 73.5%, moderate 24.9% and severe 1.6%). Prevalence of scabies among male was higher than female (39.4% vs 28.4%). Male gender (aOR 2.09, 95% CI 1.27 to 3.47, p=0.004) and age (aOR 0.95, 95% CI 0.91 to 0.99, p=0.017) were two significant predictors of scabies among children. Besides, living in Madrasahs having more boarders (aOR 1.37, 95% CI 1.06 to 1.69, p=0.025), shared bedding, clothes or toilet stuffs with other children (aOR 1.46, 95% CI 1.03 to 2.09, p=0.036) and history of pruritus in the close entourage (aOR 4.19, 95% CI 3.07 to 5.73, p<0.001) were associated with a higher chance of being infected by scabies.

CONCLUSION

Almost one-third of the children living in the Islamic boarding schools in Bangladesh are suffering from scabies, more prevalence in male and younger children. Accommodation of higher number of boarders, sharing personal staffs and pruritus in close contacts increase the risk of scabies in these children.

Scabies in the Philippines: A Secondary Analysis of Local Patient Registries

Background

Scabies is the second most common cause of disability among skin diseases in the Philippines as of 2019. There is no large nationwide study describing the epidemiologic profile of scabies in the country.

Objective

This study aimed to describe the demographic, seasonal, and geographic profile of scabies in the Philippines.

Methods

We compared secondary data of two local patient registries (Philippine Dermatological Society, PDS, 2010 to 2021; and Philippine Pediatric Society, PPS, 2009 to 2021) for reported cases of scabies in the Philippines. We reported the frequency and percentage distribution according to age, sex, month, year, and type of diagnosis, and region.

Results

The median annual frequency of scabies cases (mostly outpatient) for PDS (from year 2010) was 4087 (range ([QR], 342-6422 [3271.5]), while it was 183 (range [IQR], 64-234 [96.5]) (all inpatient) for PPS (from year 2009). There was a reduction to one-third (PDS) and one-fourth (PPS) of pre-pandemic numbers during the pandemic years (2020-2021). The peak months for scabies cases were the cooler months: January (median, 12.1% of annual cases; range [IQR], 2.6%-31.4% [3.6%]) to February (median, 10.0% of annual cases; range [IQR], 1.5%-27.8% [2.5%]) based on PDS data, and November (median, 10.0% of annual cases; range [IQR], 0.0%-24.3% [7.0%]) to January (median, 9.0% of annual cases; range [IQR], 0.0%-24.3% [6.6%]) for PPS data. Overall, for PDS, age 1-4 years is the most affected age group (median, PDS, 17.5% of annual cases; range [IQR], 11.9%-25.4% [8.1%]), while it was the less than 1-year-olds (median annual cases, 48.9%; range [IQR], 29.1%-67.3% [13.20%]) among PPS pediatric population aged 0 to 18 years. Males (median, 53.9% of annual cases; range [IQR], 45.0%-67.2% [8.8%]) were more affected than females in PPS. While for PDS during earlier years (prior to 2015), males (median, 51.6% of annual cases from 2010 to 2014; range [IQR], 47.4%-52.9% [0.2%]) were more affected than females. However, males became less affected than females with median, 44.7% of annual cases from 2015 onwards (range [IQR], 43.4%-46.5% [1.2%]). NCR was the region with the highest frequency of cases in PPS (median, 52.6% of annual cases; range [IQR], 22.7%-75.0% [20.4%]). The 2nd most affected regions were Central/Eastern Visayas (34.2%, 2009-2013; range [IQR], 17.9%-54.1% [5.3%]), Bicol region (12%; 2014 to 2018; range [IQR], 17.9%-54.1% [7.4%]), Central Luzon (18%; 2019), Central/Eastern Visayas (29%, 2020), and Northern/Central Mindanao (17%, 2021).

Conclusion

Scabies was commonly seen in the younger age group, slightly more in females in the PDS, while slightly more among males in the PPS, in the cooler months of the year, and in the urbanized NCR.

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.

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.

Cloth sharing with a scabies case considerably explains human scabies among children in a low socioeconomic rural community of Ethiopia

BACKGROUND

In 2020, scabies were integrated into the WHO roadmap for neglected tropical diseases, aimed at ending the negligence to realize the SDGs. Ethiopia has also introduced scabies as a notifiable disease in drought-prone localities since 2015. Many of the previous studies employed study designs that might be subject to bias. Moreover, there is no scientific evidence about scabies in this area. Hence, this study aimed to determine the prevalence and associated factors of scabies among children aged below 15 years in rural Ethiopia.

METHODS

A community-based cross-sectional study was carried out among 942 children in rural kebeles of Lay Gayent District from March through May 15, 2021. A two-stage sampling technique was applied. Data on sociodemographics, housing, water supply and sanitation, children's personal hygiene, and caregivers' knowledge about scabies were collected by a structured questionnaire. Data quality was maintained through pretesting, training of data collectors and supervisors, and supervision. An adjusted binary logistic regression was modelled to identify factors associated with scabies. The Hosmer-Lemeshow goodness-of-fit test was run to check the model fitness.

RESULTS

The prevalence of scabies was 21.5% (95% CI 19.0-24.3). Maternal illiteracy (adjusted odds ratio (AOR) = 1.61; 95% CI 1.07-2.43); low household wealth (AOR = 2.04; 95% CI 1.25-3.33); unimproved water source (AOR = 1.58; 95% CI 1.05-2.40); not cleaning a house daily (AOR = 2.43; 95% CI 1.63-3.62); not trimming nails (AOR = 2.21; 95% CI 1.50-3.25); cloth sharing with a scabies case (AOR = 11.77; 95% CI 6.94-19.97); and low caregiver knowledge about scabies (AOR = 2.44; 95% CI 1.64-3.63) were factors associated with scabies.

CONCLUSIONS

Scabies remains a significant public health issue among children aged below 15 years in the district. Maternal illiteracy, low household wealth, unimproved water source, not cleaning a house daily, not trimming nails, cloth sharing with a scabies case, and low caregiver knowledge about scabies were factors associated with scabies. Community-wide interventions with prime emphasis on improving maternal education and caregivers' knowledge about scabies, upgrading household wealth, ensuring a safe water supply, providing healthy housing, and ensuring adequate personal hygiene are warranted.

Prevalence of scabies worldwide-An updated systematic literature review in 2022

Scabies is a World Health Organization-defined neglected tropical disease, with continuously rising incidence worldwide in recent years. The aim of this study was to provide an update of the worldwide prevalence and new treatment approaches of scabies in population-based settings. MEDLINE (PubMed), Embase and LILACS databases were reviewed for English and German language population-based studies from October 2014 to March 2022. Two authors independently screened the records for eligibility, extracted all data and one critically appraised the quality of the studies and risk of bias. Systematic review registration: PROSPERO CRD42021247140. Overall, 1273 records were identified through database searching, of which 43 studies were included for the systematic review. Most of the studies (n = 31) examined the scabies prevalence in medium or low human development index countries. The highest prevalence of scabies reported in the general population (children and adults) was recorded in five randomly selected communities in Ghana (71.0%), whereas the highest scabies prevalence in studies, which only examined children (76.9%), was recorded in an Indonesian boarding school. The lowest prevalence was recorded in Uganda (0.18%). The systematic review highlights the prevalence of scabies worldwide, showing that scabies is still a serious, increasing disease that occurs globally and is clustered in developing countries. More transparent data on scabies prevalence are needed to identify risk factors to find new prevention measures.

Prevalence of scabies and associated factors among children aged 5-14 years in Meta Robi District, Ethiopia

BACKGROUND

Scabies is a public health problem that affects children and elders predominantly. Its burden is higher in resource-poor settings, and scabies has a significant impact on the long-term health of children. In Ethiopia, there is limited information about scabies in children. Therefore, the purpose of this study was to determine the prevalence of scabies and its associated factors among children aged 5-14 years in Meta Robi District, Ethiopia.

METHODS

A community-based cross-sectional study design using a multistage sampling technique was used to collect data from 457 participants by systematic random sampling. Scabies was diagnosed based on the clinical criteria set by the International Alliance for the Control of Scabies (IACS, 2020).

FINDINGS

The prevalence of scabies among children aged 5-14 years old was 19.26% (95%CI: 17.20-22.52). In addition, over half (54.6%) of identified cases of scabies were of moderate severity. Factors like families' low income (aOR = 2.72; 95%CI: 1.32-5.59), being a male child (aOR = 1.96, 95%CI: 1.61-4.01), using only water for hand washing (aOR = 2.01, 95%CI: 1.84-4.79), having a contact history of scabies/skin lesions (aOR = 4.15, 95%CI: 2.02-13.67), and sharing sleeping beds (aOR = 6.33, 95%CI: 2.09-19.13) were significantly associated with scabies.

CONCLUSION

The study highlights a high prevalence of scabies among children aged 5-14 years in the district. Provision of adequate health education for the community and children about the scabies and delivering mass drug administration to the district is suggested.

Prevalence of skin Neglected Tropical Diseases and superficial fungal infections in two peri-urban schools and one rural community setting in Togo

INTRODUCTION

Skin neglected tropical diseases (NTDs), are endemic and under-diagnosed in many lower-income communities. The objective of this study was to determine the prevalence of skin NTDs and fungal infections in two primary schools and a community setting in rural Togo.

METHOD

This was a cross-sectional study that took place between June-October 2021. The two primary schools are located on the outskirts of Lomé, the capital city. The community setting was Ndjéi, in north-east Togo. Study sites were purposively selected. Dermatologists examined the skin of study participants. Diagnosis of skin NTDs were made clinically.

RESULTS

A total of 1401 individuals were examined, 954 (68.1%) from Ndjéi community, and 447 (31.9%) were children in the schools. Cutaneous skin infections were diagnosed in 438 (31.3%) participants, of whom 355 (81%) were in community settings. There were 105 observed skin NTDs (7.5%). Within the school setting, there were 20 individuals with NTDs (4.5% of 447 participants), and 85 NTDs (8.9%) from 954 community participants. Across all settings 68/1020 (6.7%) NTDs were in children, and 37/381 (9.7%) in adults. In addition, there were 333 observed mycoses (23.8% prevalence). The main cutaneous NTDs diagnosed were scabies (n = 86; 6.1%) and suspected yaws (n = 16, 1.1%). The prevalence of scabies in schools was 4.3%, and 7.0% in the rural community. One case of leprosy was diagnosed in each school and the rural community, and one suspected Buruli Ulcer case in the community. In the school setting, five (6%) children with a skin NTD reported being stigmatised, four of whom had refused to attend school because of their dermatosis. In Ndjéi, 44 (4.6%) individuals reported having experienced stigma and 41 (93.2%) of them missed at least one day of school or work.

CONCLUSION

This study shows that the burden of scabies and skin infections such as superficial mycoses is high in the school and rural community settings in Togo, with associated presence of stigma. Improved health promotion and education across institutional and community settings may reduce stigma and encourage early reporting of skin infection cases to a health facility.
