  • ISSN : 0008-9176



2551 human sera were collected from 16 locations in the Mashonaland, Matabeleland, Manicaland and Victoria provinces of Rhodesia and from hospitalised patients in Salisbury between November, 1968 and March, 1973. The sera were tested for antibodies to Chikungunya, Sindbis, Wesselsbron, West Nile and Rift Valley Fever viruses. Evidence was obtained of high levels of activity of Chikungunya and Wesselsbron viruses at many of the sites and of lower levels of activity of Sindbis and West Nile virus at some of the sites. Rift Valley Fever antibodies were found in sera from the Zambezi Valley and the infection was diagnosed in a farmer and veterinary staff during the 1969 epidemic in livestock in Mashonaland. The findings are discussed in relation to existing knowledge on the epidemiology and medical significance of each virus.
