Eastern encephalitis (EE) v?rus was successfully isolated from 16 sentinel hamsters exposed to a wet tropical forest environment in the farnorthern reaches of the Brazilian Amazon. The place of exposure. a settlement named Uaica near the Brazil-Venezuela border, is surrounded by hundreds of square kilometers of virgin forest. Tests run on sera from Yanomama lndians who had lived in the area indicated local human exposure to the v?rus was very slight. Therefore. the detection of intense EE virus activity in this area provides further evidence of a truly sylvatic EE cycle outside the present sphere of human influence.
