During the period February 11. 1994-May 31. 1995 faculty and students at Uniformed Services University of the Health Sciences along with members of the staff of the Epidemiology Research Center in Belize accomplished five studies. A study of risk factors and social correlates of malaria among Mayan Indians in Belize who experience very high rates of malaria each year revealed that housing is not mosquito resistant. personal protective measures are not used, treatment was irregular, and reporting of malaria slide results is delayed. A one year study of hepatitis in Stann Creek district revealed the major etiologic agent of jaundice to be hepatitis B. Those with the highest incidence are Mayan Indians and Spanish speaking agricultural workers in the southern part of Stann, Creek district of Belize. A study of the seroprevalence of hepatitis B in school aged children in Stann Creek district indicated that the majority of children in two rural communities studied are exposed to hepatitis B before entering school while the prevalence of children in coastal towns is lower. A hepatitis B vaccine trial comparing three 5ug doses of Recombivax HB with two lO-ug doses was conducted among the Belize Defense Force results are pending. A serologic study of Chagas Disease was continued among blood donors only 0.08 of blood donors had antibody to T. cruzi.
