| an outbreak of rift valley fever in northeastern kenya, 1997-98. | in december 1997, 170 hemorrhagic fever-associated deaths were reported in garissa district, kenya. laboratory testing identified evidence of acute rift valley fever virus (rvfv). of the 171 persons enrolled in a cross-sectional study, 31(18%) were anti-rvfv immunoglobulin (ig) m positive. an age-adjusted igm antibody prevalence of 14% was estimated for the district. we estimate approximately 27,500 infections occurred in garissa district, making this the largest recorded outbreak of rvfv in eas ... | 2002 | 11897064 |
| continuing presence of rinderpest virus as a threat in east africa, 1983-1985. | the re-emergence of rinderpest virus in east africa in 1979 caused widespread outbreaks of disease and subclinical infection throughout the region until mid-1983. subsequent massive emergency vaccination campaigns have been successful in eliminating clinical rinderpest from tanzania and preventing its spread southwards. unfortunately the virus is still endemic in north-eastern uganda and has recently caused epidemic outbreaks with high mortality in cattle in that country. in kenya, buffaloes (sy ... | 1987 | 3824842 |
