Over 90 percent of the burden of malaria lies within sub-Saharan Africa, with young children and pregnant women being most at risk. Estimates would suggest that over 600,000 cases and nearly 2,000 children will die as we observe World Malaria Day. Dr. Sunil Parikh, an assistant professor in the department of epidemiology of microbial diseases at the Yale School of Public Health, has studied malaria since early in his career. Much of his research now is in Africa, particularly Uganda and Burkina Faso, countries particularly hard hit by the mosquito-borne infection.
