Outbreak of scabies among preschool children, Accra, Ghana, 2017.

BACKGROUND: Scabies occurs worldwide with a prevalence between 0.3 and 46.0%. In Ghana, even though a 5.1% proportion of scabies was reported in a retrospective review of skin diseases at the Korle Bu Teaching Hospital, the nationwide prevalence of scabies is unknown. Overall, its burden is higher in tropical regions. Scabies outbreaks mostly occur among children, the elderly in nursing homes, and prison inmates. Even though primary scabies hardly results in mortalities, the pain, itch, and systemic complications from secondary bacterial infections account for about 1.5 million years lived with disabilities. We investigated a scabies outbreak among school children in Ghana to determine its magnitude, stop the outbreak, and institute preventive measures to minimize risks of future outbreaks. METHODS: The investigation was conducted between March 14 and May 17, 2017 among pupils of Presbyterian Secondary Staff Basic School in Accra. We defined a case as a school child who on clinical examination, had an intensely pruritic rash on at least one typical predilection site with or without a burrow, or positive skin scrapings on microscopy. We screened and line listed cases, performed laboratory investigations on skin scrapings and wound swaps, and conducted an environmental assessment. We performed descriptive statistics on data, and calculated attack rate ratios (ARR) at 95% confidence level. RESULTS: Of 823 preschool children screened, 92 were cases. Median age of cases was 4 years (range 2-7 years) and their modal age was 3 years. The overall attack rate was 11.2% (92/823). The sex specific attack rate was 11.5% for males, and 10.8% for females (ARR: 0.93; CI: 0.67-1.28). Compared with the least affected class (crèche), the nursery one class was worst affected (ARR: 5.14; CI: 3.44-7.50). On microscopy, all skin scrapings were negative for scabies. Staphylococcus aureus and Streptococcus spp. were isolated from secondarily infected scabies lesions. CONCLUSIONS: A scabies outbreak with a propagated source occurred among preschool children. The 3-year-old pupils were most affected. It was controlled by mass treatment with benzyl benzoate and health education. Classrooms and sleeping mats were disinfected. We recommended the decongestion of classrooms and discouraged sharing of sleeping mats.

Hand hygiene and face mask wearing practices for COVID-19 prevention: a non-intrusive observation of patrons of community convenience shops in Accra, Ghana.

INTRODUCTION: in the absence of a vaccine and definitive treatment, non-pharmacological measures of physical distancing, regular hand hygiene and wearing of face covering remain the mainstays of mitigating coronavirus disease 2019 (COVID-19). In Ghana, these measures are mandatory in public places and underpin COVID-19 infection prevention and control (IPC). We assessed adherence and appropriate performance of these measures among patrons of community convenience shops in selected hotspots. METHODS: we conducted a non-intrusive observation of patrons of convenience shops in COVID-19 burden hotspots. We observed patrons as they entered and exited the shops and collected data on their gender, adherence and appropriate use of face covering and hand hygiene facilities. Data were analyzed descriptively and inferentially to determine factors associated with adherence to IPC guidelines. RESULTS: of 800 patrons observed from eight community shops, 481 (60.1%) were males. Of these, 653 (81.6%) wore face covering and 98 (12.3%) performed hand hygiene; with 92 (11.5%) adhering to both measures. Patrons who wore face mask appropriately were 578; comprising 299 (92.3%) of patrons who wore face mask before entering the shops. Of 89 patrons who washed their hands, appropriate handwashing was recorded among nine (10.1%). Compared to inappropriate handwashing, appropriate handwashing was negatively associated with adherence to IPC guidelines [aOR=0.1 (95% CI=0.01-0.59)]. CONCLUSION: adherence to and appropriate performance of IPC measures of handwashing and use of face covering in the selected shops was low. There is the need to complement availability of IPC measures with intensification of risk communication messaging targeted at ensuring their appropriate use.
