Effect of drug treatment on the prevalence of intestinal parasites amongst school children in a sub-urban community.
The prevalence of intestinal protozoal and helminthic infection was studied over a period of one year amongst 297 school children, aged 5-20 yr in a sub-urban area. The overall prevalence rate of various protozoal infection, 15.82 per cent had only helminthic infection and 14.47 per cent had combined helminthic and protozoal infection. Ascaris lumbricoides infestation was found to be the commonest helminthic infection (61.70%) while giardiasis was the commonest protozoal infection (59.80%). The prevalence rates, one year after effective anti-protozoal and antihelminthic treatment was administered, were overall parasitic infection 25.92 per cent; only protozoal infection 17.50 per cent, only helminthic infection 5.72 per cent and combined infection 2.69 per cent. The reinfection rate was found to be 7.40 per cent and the fresh infection rate was found to be 11.4 and 39.8 per cent at the end of six months and one year respectively.
