Pattern of Schistosoma mansoni infection after intervention in Mwea irrigation scheme in Kenya.
A longitudinal study of Schistosoma mansoni reinfection rate was carried out in an endemic area of Kenya, after intervention. Intervention measures applied involved chemotherapy, community mobilization to effect change in water contact habits and faecal disposal. This paper focuses on S. mansoni reinfection pattern over a two-year period. The age group 5-19 years showed an increasing trend of reinfection as compared to the 30-59 years age group. More than 50% in the 5-19 year age group had been reinfected by twelve months of follow-up. They were also responsible of 91% of all the egg-load and 83% of all the infections at the end of the study period. Since majority of the 5-19 year age group comprises school children, there is an urgent need of including issues related to schistosomiasis in the school curriculum especially in the endemic areas.
