Abstract : Two major findings related to virus taxonomy were (1) the Nairovirus Supergroup of Bunyavirus-like agents including groups Congo-Crimean hemorrhagic fever, Nairobi sheep disease, Dera Ghazi Khan, Qallyub, Hughes, and possibly Sakhalin, and (2) the serologic relationship of Rift Valley fever virus to the phlebotomus fever group. Viruses were studied from Australia, Fiji, Iran, Rhodesia, Kenya, France, Brazil, Gambia, Philippines, Central African Republic, Ethiopia, and USA. A survey of residents of China, mostly of the Peking area showed a very high prevalence of group B, probably Japanese encephalitis reactivity. A high percentage of Liberian human sera had group B and group A (probably chikungunya) reactivity. The first case of disease associated with Pichinde infection in a laboratory worker was diagnosed serologically. Ross River infection was recognized in Canadian tourists returning from Fiji. A focus of LaCrosse encephalitis infection was studied north of New York City.
