Epidemiological Notes on Some Viruses Isolated In Uganda (Yellow fever, Rift Valley fever, Bwamba fever, West Nile, Mengo, Semliki forest, Bunyamwera I Ntaya, Uganda S and Zika viruses)
Resumen
During a period of 10 years (1937-1947) 10 different viruses were isolated at the Yellow
Fever Research Institute (now Virus Research Institute), Entebbe, Uganda. Two of these,
yellow fever and Rift Valley fever virus, had been studied in considerable detail prior to
their isolations in Uganda, but the nature of the Uganda isolations has greatly helped to
unravel the natural history of the former and suggested some epidemiological links which
may be of importance in the development of our knowledge of the epidemiology of the latter.
Of the remaining eight viruses, all were thought to be hitherto unknown agents and subsequent
studies confirmed this belief except in the case of one of them, namely Mengo encephalomyelitis virus, which was shown to be related to the Columbia SK, MM and encephalomyocarditis
viruses (DICK, 1949; WARREN, SMADEL and Russ, 1949; OLITSKY and YAGER, 1949).
