Background: Schistosomiasis is prevalent in many sub-Saharan African countries and transmission is through waters contaminated by infected snails. In Rwanda, although schistosomiasis is endemic, very few epidemiological studies exist; of these, schoolchildren have been the focus, neglecting pre-school-aged children (PSAC). Furthermore, malacological surveys to indicate the potential for transmission are scarce in the country. The aim of this study was to determine the prevalence of schistosomiasis among PSAC living on Nkombo Island in Lake Kivu and to map the distribution and infectivity of snails in the area. Methods: Stool and urine samples were collected from children aged 1 to 4 years and tested for schistosomiasis using the Kato Katz and the point-of-care circulating cathodic antigen (POC-CCA) diagnostic techniques respectively. Snails were collected along the shores at five different locations with human-water contact activities and cercaria shedding was microscopically examined. GPS receivers were used to collect geographical coordinates and snail distribution maps were generated using ArcGIS. A questionnaire was used to assess water contact activities and frequency.     Results: A total of 278 PSAC were recruited. Overall, 9.5% (excluding traces) of the tested children reacted positively to the POC-CCA, although there were no ova detected in their stool via Kato Katz. The questionnaire revealed that 48.2% of parents/guardians use Lake Kivu’s water for household activities while 42.4% children are taken to the Lake shores daily. Overall, 13.5% of collected snails shed cercariae. Conclusions: PSAC of Nkombo Island are exposed to Schistosoma parasites through contact with Lake Kivu, which hosts a number of snails shedding cercaria. Exposure is through recreational activities but also through bathing as safe water is scarce in the area. Health education of parents/guardians of these young children should be promoted and the national schistosomiasis control program should be integrated into water supply projects.

Background: In response to the need for interventions that facilitate the accessibility of medical services in poor communities, an outreach activity was organized in semi-rural areas of Maraba and Simbi sectors located in Huye district, Southern province of Rwanda. The outreach was undertaken by health sciences students and involved the screening of hypertension, risk of diabetes, hepatitis, anemia, eye disease, and HIV.Methods: Clinical assessments and rapid laboratory diagnostic assays were used to screen invited residents from the two selected communities. An observation research was conducted from May 21 to 25 May, 2018, at Maraba and Simbi sector located in Huye district, Southern province, Rwanda. We employed a purposively sampling technique for participants' recruitment in the outreach. The outreach was conducted as part teaching program and community engagement, and was endorsed by college of medicine and health sciences and all the subjects voluntarily participated in this exercise; the ethical approval was not applicable for this outreach activity. Results: The total beneficiaries from those sectors were 1427 citizens of whom females predominated at 72%. During the screening, hypertension was found to be high at 47.8% among adults. Anemia which mostly presumes iron deficiency was observed at 32.5% among under 15 years old children and at 15% in pregnant women. The vision impairment and cataract were observed at 5.66 and 19.59%, respectively. The assessed viral infection indicated a rate of 0.56% for HIV, 1.03% for HBV, and 7.17% for HCV. High blood glucose was found in 10.4% of the screened population.Conclusions: The findings highlight a high burden of non-communicable diseases (NCDs) in rural communities and call for further investigations and interventions to align with the sustainable development goals (SDGs), particularly access to affordable health services. Furthermore, the success of this outreach highlights the potential contribution of health care trainees in achieving these goals and calls for integration of such interventions in the health education curriculum.
