Epidemiology of schistosomiasis in the town of Manjo, littoral - Region,Cameroon.

BACKGROUND

Schistosomiasis is endemic in Cameroon and continues to cause serious public health problems, especially among populations in rural areas. This study aimed at determining the prevalence and risk factors of urinary and intestinal schistosomiasis in Manjo.

METHOD: A cross-sectional study was conducted in the city of Manjo in 2020. Stool and urine samples were collected from 400 participants. These stool and urine samples were examined by the Kato Katz, and centrifugation methods respectively.

RESULTS

The results obtained showed an overall prevalence of 6.25%, with 5% and 1.25% for S. mansoni and S. haematobium respectively. A significant difference (p < 0.05) was revealed among occupations, age groups, neighborhood, water usage, educational level, knowledge of the disease meanwhile no significant difference was observed between gender and occupation according to prevalence. The most infected ages were] 50-; + [and]20-35] with 13.36% and 11.86% respectively. S. haematobium revealed a low infection intensity while S. mansoni showed moderate infection intensity. The mean parasite load for S. haematobium was 6 ± 3.225 Eggs/10 ml in females and 7 ± 4.243 Eggs/10 ml for males; while the mean parasitic load in S. mansoni was 180 ± 142.441 Epg in females and 146.67 ± 82.286 Epg in males.

CONCLUSION

Manjo can be classified as a low endemic area with a prevalence rate of 6.25% and species observed were S. haematobium and S. mansoni. Also, risk factors where observed including the use of water from the river for domestic purposes. Therefore, the intensification of health education campaigns among the population would delay the development of this disease in the locality.
