Background: Soil transmitted helminth infections are Neglected Tropical Diseases (NTD) affecting mostly pupils in developing countries. They seem to lose more and more interest due to the fact that resources and research are being justifiably diverted to more recent priorities such as HIV/AIDS, cancers, tuberculosis and malaria. As a result, specific data on STH infections is often lacking. Aims: To evaluate the prevalence and intensities of STH parasites among pupils in Penka-Michel Sub-division, West-Cameroon in order to refresh information for a better management of these parasitic diseases. Settings and Design: A cross-sectional analytic study was conducted from October to December 2018 in Penka-Michel Sub-division. Methods and Materials: To evaluate the prevalence and intensities of STH parasites among pupils, seven hundred and twenty nine (729) stool samples were collected from pupils aged 4 to 14 years old in 23 randomly selected primary schools. The samples were analysed using the concentration method of Willis and the Mc Master technic. Results: Out of 729 pupils enrolled, 107 (14.7%) were infected with one or more STH parasite species. The nematodes species identified were Ascaris lumbricoides (9.9%), Trichuris trichiura (5.3%) and hookworms (2.2%). Pupils aged from 8 to 11 years were the most infected (17.3%). Statistically females were more infected with hookworms (2.2%). These parasites occurred as monospecific (84.11%), bi-specific (13.0%) and tri-specific (2.80%) infections. The mean fecal eggs count was 3652.78±8715.93, 266.67±273.81 and 118.75±72.74 for A. lumbricoides, T. trichiura and hookworm respectively. According to faecal concentration of eggs, 88.18% of infections were light. Conclusion: These results show the necessity of sustainable application of regular deworming, health education and improvements in sanitation among pupils in Penka-Michel Sub-division.

Background: Soil transmitted helminth (STH) infections disproportionately affect poor populations in tropical and subtropical parts of the world. They contaminate soil and pupils are mostly at risk of these infections due to their soil related habits. Aims: to assess pupils’ knowledge, attitude and practice in relation to the rate of soil contamination in public primary schools. Methods: Structured questionnaires were administered to 729 consenting participants to obtain information on their awareness status of STH infections. A total of 552 soil samples were collected around toilets, classrooms backyards and playground in 23 public schools randomly selected in Penka-Michel subdivision and examined for the presence of STH eggs using the sucrose flotation method. Results: up to 80% of respondents do not actually know how to avoid getting infected with worms. About 50% of pupils do not actually wash their hands after defecating or wash their fruits/vegetables before eating. Pupil’s nails were mostly untrimmed (74.1%). 77.1% declared they always defecate out of the toilets when they are in school. Out of 552 soil samples examined, 97 (17.6%) were contaminated by Ascaris sp, Trichuris sp, Toxocara sp, Capillaria sp, Cooperia sp, hokworms and Nematodirus sp. Soil from around toilets were significantly more contaminated with Ascaris sp and Trichuris sp eggs. Soil contamination was also significantly associated with absence of water during class hours, unhygienic conditions of toilets, and lack of school perimeter fence. Overall 65% of schools selected showed a low level of hygiene. Conclusion: Pupils of these schools played a major role in the contamination of their environment. Therefore, in order to prevent the STHs transmission cycles in school environment and possibly in pupils, it is necessary to develop specific sustainable intervention programs.
