LYMPHATIC FILARIASIS AND MALARIA - CONCOMITANT PARASITISM IN ORISSA, INDIA

Concomitant parasitism with Plasmodium spp. and Wuchereria bancrofti w as examined in Orissa, India, to study the influence of one parasite i nfection on the other in human communities. A survey of 1815 nocturnal blood films in 11 villages indicated an overall prevalence of 9.6% fo r malaria and 8.5% for microfilaraemia. Only 0.3% of the population ha rboured both parasites. Analysis of the expected and observed distribu tion of cases of dual infection in each village did not indicate any s ignificant interaction between the 2 infections. The malarial vector d ensity in 3 selected villages correlated well with the prevalence rate of malaria.
