Isolation of Ilhéus virus from human beings in Trinidad, West Indies

Abstract
Three strains of Ilhéus virus were isolated from human beings in Trinidad. One of these isolations was made from a female resident of Port-of-Spain who suffered a severe febrile illness. The other two strains were isolated from mosquito catchers who worked in the forests of eastern Trinidad. One of these men had a mild febrile illness at the time of the isolation, and the other was in good health. The serological reactions in these three cases of Ilhéus infection are reported.
