“…[10] Conversely, this prevalence was close to the observations made by Alonzo et al .,[11] who registered a prevalence of 51.6% in Benin and lower to that obtained in Bawa and Nloh, two rural Cameroonian villages. [12] In the present study, we noticed that the prevalence increases with age. Similar observations were made by Menan et al .…”

Background:In recent times, soil-transmitted helminth (STH) infections seem to loose more and more interest due to the fact that resources are being justifiably diverted to more recent priorities such as HIV/AIDS and malaria. In developing countries, the upsurge of intestinal helminth infections constitutes a problem not only of public health concern but also of development.Aim:To find out the prevalence of STH infections in persons visiting the traditional health care centre in west Cameroon.Materials and Methods:In order to evaluate the prevalence and intensity of STH infections, in persons visiting the centre of phytomedecine, a parasitological investigation of feces was carried out in 223 stools, using three techniques (direct examination, concentration method of Willis, and Mc Master technique).Results:130 stools were collected from male and 93 from female subjects, hence a sex ratio of 1.4:1. Among the 223 stools examined, 97 specimens were found to be positive with one or several parasite species, thus giving a prevalence of 45.3%. The parasitism occurs from early age (1-10 years) reaching 4.5%. The most infected age group was 21-30 years (31%). Female subjects (28.3%) were statistically more infected than males (15.2%). The intestinal nematode species found were Trichuris trichiura (19.2%), Ascaris lumbricoides (13.4%), and hookworm (10.7%). These parasites occurred as single (19.2%) or multiple infections (10.3%). The mean fecal eggs count was 3722±672, 875±462, and 563±283 for A. lumbricoides, hookworm, and T. trichiura, respectively.Conclusion:These results show the necessity of the application of suitable measures which are aimed at reducing the extent of STH.

Background Soil-transmitted helminths (STH) infections remain an important public health problem in the tropics. This study aimed to evaluate the soil contamination rate and prevalence of infestations of geohelminth among residents in Bazou. Methods Four hundred (400) soil samples and 182 stool specimens were collected respectively from four sites and from inhabitants aged 1 to 40 years and above in 12 households. A questionnaire was administered to evaluate risk factors of STH-infections. Soil samples were screened using sucrose centrifugal flotation method while stool specimens were analyzed using two techniques. Results Out of the 400 soil and 182 stool samples examined, 13(3.3%) and 9(4.95%) were positive respectively after analyses. Soil contamination rates were 2%, 1% and 0.3% for Ascaris, Trichuris and hookworm eggs respectively while 4.95% of stool samples were positive to one species nematode (Ascaris lumbricoides). The soil contamination rate observed (5%) in the rainy season was significantly different (p>0.05) from the one observed (1.5%) in the dry season. Irrespectively of the season, the most frequent parasite identified was Ascaris spp. Soils around houses were more contaminated 6(12%) as compared to those collected from markets 5(10%) and roads 2(4%) while those around classrooms were not contaminated. Participants in the age group of 1–10 were more infected. Factors such as no hand washing habit and untrimmed finger nails were found to be important risk factors for STH. Conclusion These results suggest the necessity to promote measures that could help to reduce STH infections.

“…They are most prevalent in regions exhibiting warm and moist climates coupled with poor sanitation and hygiene. Epidemiologically, there is no target age with STH infection, but the highest rates occur among children living in rural areas of the tropical and subtropical regions [6,7,8]. Morbidity associated with STH infection are directly related to the intensity of infection, hence heavily infected children experience pathological sequels such as mal-absorption of nutrients, iron deficiency anemia, impairment of physical and mental development, which ultimately retards their educational advancement, expose them to other diseases and affect economic development of the nation [9,4,10] .…”

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.
