(l) A descriptionption is given of the symptomatology and epidemiology of an outbreak of chikungunya which occurred from January to May, 1962, in the south-eastern area of Southern Rhodesia. (2) One strain of virus was isolated from a patient. This virus was identified by the complement-fixation, haemagglutination i?½ inhibition and neutralisation tests as chikungunya virus. (3) Antibody studies with the haemagglutination- inhibition test on acute and convalescent phase sera from patients showed a high prevalence of antibodies against chikungunya virus. (4) A total of 185 mosquitoes from 21 species were collected in the affected area in May towards the end of the outbreak. No virus was isolated from the mosquitoes. (5) The possible vectors concerned in the outbreak are discussed.
