Serological Evidence of Arbovirus Infection in the Seminole Indians of Southern Florida

Abstract

A serological survey of the Seminole Indians in south Florida for evidence of exposure to arbovirus infection indicated not only past infection with the recognized North American encephalitis viruses-a high incidence for St. Louis encephalitis-but exposure to a Bunyamwera group agent and to Venezuelan equine encephalitis virus, activity of which had not been previously recognized north of Panama.
