Burden of human scabies in sub-Saharan African prisons: Evidence from the west region of Cameroon

[PREVALENCE AND ASSOCIATED FACTORS OF HUMAN SCABIES IN PRISONS IN DOSSO, NIGER]

Background

Scabies is a contagious, pruritic, cosmopolitan dermatosis, widespread especially in human communities, due to parasitism by a mite Sarcoptes scabiei var hominis A lack of hygiene and overcrowding inside the houses are favourable factors. The aim of our study was to determine the prevalence and factors associated with the occurrence of human scabies in the prison environment in Dosso (Niger).

Materials and methods

Prospective descriptive cross-sectional study conducted in November 2022 in the civil prison of Dosso on authorization of the prison administration. The collected data were sociodemographic characteristics, personal history of pruritus and its characteristics, risk factors related to hygiene and conditions of incarceration, examination performed by a dermatologist to look for clinical signs of scabies. The diagnosis was retained in any inmate presenting one or more elements at the interrogation and at the physical examination.

Results

Out of a total of 352 inmates, 43 (38 males and 5 females) had scabies, a prevalence of 12%. The average age was 33 with extremes of 18 and 62 years. Of the scabies patients, 9% reported a history of intense, sleepless pruritus prior to incarceration. Most of the inmates, 86%, were in cells with more than 20 inmates. Among those with scabies, 42% showered twice a day, 81% changed clothes after showering and 74% used soap regularly for washing. The topography of the lesions was external genitalia (37%), buttocks (21%), inner thighs (16%), interdigital spaces (9%), elbows (9%) and wrists (7%). The inmates were informed about the disease, treatment information was explained to them, and they attended a session on hygiene promotion. All cases of scabies detected were prescribed a local treatment based on benzyl benzoate lotion 25%.

Discussion/conclusion

Human scabies is common in the prison environment in Dosso. Too often, scabies goes undetected and is confused with other pruritic dermatoses, such as eczema or atopic dermatitis. Prison medical staff should be trained in scabies in order to prevent scabies outbreaks. The authorities in the region should make the improvement of hygiene and detention conditions in prisons their priority.

Skin Diseases and their Treatment Strategies in Sub-Saharan African Regions

BACKGROUND

In the rural areas of sub-Saharan African regions, skin diseases are so common. Due to which the population of the sub-Saharan region suffers from different types of skin disorders. In these regions, many treatment options are not available for the treatment of skin disease.

AIM

The current study aims to discuss various skin diseases and their treatment strategies specifically in sub-Saharan African regions.

METHOD

Extensive literature survey was carried out by using scopus, science direct, elsevier, google scholar and bentham science databases.

RESULT AND DISCUSSION

It was demonstrated from the literature surveys that different effective techniques are used in the management of skin disease. In the result, it was shown that the condition of the disease is at a dangerous level which must be controlled.

CONCLUSION

It is concluded from the manuscript that the skin disorder in the sub-Saharan region is at a very dangerous level. The research must be done to develop a better understanding of the disease and its treatment.

Prison health priorities in Burkina Faso: a cross-sectional study in the two largest detention environments in Burkina Faso

PURPOSE

The purpose of this paper is to study the factors associated with the occurrence of diseases and beriberi among prisoners incarcerated in the two largest Remand and Correctional Facilities (RCF).

DESIGN/METHODOLOGY/APPROACH

This was a cross-sectional descriptive and analytical study carried out from April 20 to May 19, 2017, in the RCFs of Ouagadougou and Bobo-Dioulasso. All prisoners who consulted and those referred to the health center by the health-care team were included in the study. Complaints and diagnosed diseases information were collected using the second version of the International Classification of Primary Care (ICPC-2). The authors used a logistic regression model to perform univariate and multivariate analyses.

FINDINGS

Of the 1,004 prisoners from the two RCFs included in the study (32.6%), 966 (96%) were male. The median age was 31.6 years. The distribution of diseases diagnosed using the ICPC-2 showed a predominance of gastrointestinal tract, skin and respiratory tract diseases among 206 (19.3%), 188 (17.6%) and 184 (17.2%) prisoners, respectively. A total of 302 prisoners (30.1%) had clinical beriberi, and 80 prisoners (8%) were underweight. Being incarcerated for more than nine months was independently associated with a high risk of digestive and respiratory diseases as well as beriberi.

RESEARCH LIMITATIONS/IMPLICATIONS

This study highlighted higher frequencies of digestive, skin and respiratory complaints and diseases in the two largest detention centers in Burkina Faso. These diseases are variously related to age, penal status and length of incarceration. In addition, underweight and thiamin vitamin deficiency responsible for beriberi are more frequent in adult prisoners, those not attending school, convicted prisoners and those with a length of stay in detention of more than nine months. These concrete results should help define a strategy and priority actions needed to reduce morbidity in prisons.

PRACTICAL IMPLICATIONS

The actions should include the intervention of specialists in the field of common diseases in prisons, the improvement of individual hygiene conditions and environment, the improvement of the quality and quantity of the food ration, a strategy to reduce prison overcrowding. Other actions must be planned to allow specific groups such as women and minors to have access to health care that is adapted to them. Beyond the central concern of promoting the rights of prisoners and humanizing prisons, actions to improve the health of prisoners are part of an overall public health approach with its socio-economic and environmental implications.

SOCIAL IMPLICATIONS

There is a need for a strong commitment from the State to develop a prison health policy that prioritizes the prevention of communicable and non-communicable diseases that are particularly prevalent in this context, without forgetting mental health and nutrition. This requires a collaboration of stakeholders based on better intersectorial communication, the implementation of a monitoring and evaluation system for the health of prisoners, an enhancement of the status of health-care providers working in prisons and an increase in the funding allocated to the health of prisoners with the mobilization of the necessary funds.

ORIGINALITY/VALUE

This study uses a primary health care classification to assess the health of inmates in a prison in Africa. It contributes to the weak evidence around prison health surveillance and health profiling of prisoners in Africa.

Intervention protocol to improve scabies control in enclosed communities: a case report

OBJECTIVES

To describe patients with scabies in a prison setting. Document what type of treatment was carried out. Prepare an intervention protocol to improve scabies control in the Penitentiary Center.

MATERIAL AND METHOD

All cases of scabies diagnosed in the Youth Detention Centre (La Roca del Vallès, Barcelona) between November 2018 and November 2019 were recorded. The treatment used was recorded. Bibliographical research on the protocols and treatment guidelines was carried out for community-acquired scabies.

RESULTS

The study was performed with 762 inmates, of whom 61 patients were diagnosed with scabies. 39 patients' pathologies were detected at the time of admission to the center, 11 cases were diagnosed in the first 6 weeks after entering the prison, coinciding with the incubation period of the disease. Finally, 11 more were diagnosed when they had already been in prison for more than 6 weeks and therefore could be infected cases within the center. This parasitosis was detected mainly in inmates of North African origin, 14.7% of Algerian inmates and 14.2% of Moroccan inmates presented this pathology, compared to 1.6% among Spanish prisoners. All 61 patients were treated with permethrin and 8 cases had to repeat the treatment cycle due to apparent therapeutic failure. Research literature indicates that oral ivermectin should be the drug of first choice for the treatment of scabies in prison.

DISCUSSION

The high incidence of scabies cases detected in prison led us to carry out a bibliographic review that brought about changes in the treatment protocol that may be of interest for the control of the disease in closed communities.

A scabies outbreak in the North East Region of Ghana: The necessity for prompt intervention

Background

There is a dearth of data on scabies from Ghana. In September 2019, local health authorities in the East Mamprusi district of northern Ghana received reports of scabies from many parts of the district. Due to on-going reports of more cases, an assessment team visited the communities to assess the effect of the earlier individual treatment on the outbreak. The assessment team furthermore aimed to contribute to the data on scabies burden in Ghana and to demonstrate the use of the International Alliance for the Control of Scabies (IACS) diagnostic tool in a field survey in a resource limited setting.

Methodology/Principal findings

This was a cross sectional study. Demographic information and medical history was collected on all participants using a REDCap questionnaire. A standardised skin examination of exposed regions of the body was performed on all participants. Scabies was diagnosed based on the criteria of the International Alliance for the Control of Scabies (IACS). Participants were mostly female (61.5%) and had a median age of 18.8 years (IQR 13–25). Two hundred out of 283 (71%) of participants had scabies with most (47%) presenting with moderate disease. Impetigo was found in 22% of participants with scabies and 10.8% of those without scabies [RR 2.27 (95% CI 1.21–4.27)]. 119 participants who received scabies treatment in the past months still had clinical evidence of the disease. 97% of participants reported a recent scabies contact. Scabies was commoner in participants ≤16 years compared to those >16 years [RR 3.06 (95% CI 1.73–5.45)].

Conclusion/Significance

The prevalence of scabies was extremely high. The lack of a systematic approach to scabies treatment led to recurrence and ongoing community spread. The IACS criteria was useful in this outbreak assessment in Ghana. Alternative strategies such as Mass drug administration may be required to contain outbreaks early in such settings.

Scabies, recently categorised as a Neglected Tropical Disease by the WHO is caused by infestation with Sarcoptes scabiei and is characterised by intense pruritus and rash that typically involves the genitalia and the web spaces of the fingers and toes. It has a large global burden and is associated with significant morbidity and socio-economic burden. Secondary bacterial infections following scabies can lead to significant complications including chronic kidney disease from glomerulonephritis and possibly rheumatic heart disease. An outbreak of scabies was reported in Ghana’s East Mamprusi district in September 2019. Despite earlier treatment of individual cases, scabies prevalence was 71%. About 19% of participants had impetigo which was mostly mild in severity. Absence of a systematic approach to treat scabies led to recurrence and ongoing community spread. The recently published IACS criteria for diagnosing scabies proved useful in this outbreak assessment in Ghana. Alternative strategies such as Mass drug administration may be required to contain outbreaks in such settings.

The public health control of scabies: priorities for research and action

Scabies is a parasitic disease of the skin that disproportionately affects disadvantaged populations. The disease causes considerable morbidity and leads to severe bacterial infection and immune-mediated disease. Scientific advances from the past 5 years suggest that scabies is amenable to population-level control, particularly through mass drug administration. In recognition of these issues, WHO added scabies to the list of neglected tropical diseases in 2017. To develop a global control programme, key operational research questions must now be addressed. Standardised approaches to diagnosis and methods for mapping are required to further understand the burden of disease. The safety of treatments for young children, including with ivermectin and moxidectin, should be investigated. Studies are needed to inform optimum implementation of mass treatment, including the threshold for intervention, target, dosing, and frequency. Frameworks for surveillance, monitoring, and evaluation of control strategies are also necessary.

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].
