the ecology of west nile virus in south africa and the occurrence of outbreaks in humans. | this paper reviews studies done on west nile virus (wnv) in south africa, mainly between 1962 and 1980 on the temperate inland plateau (highveld and karoo). the virus is maintained in an enzootic transmission cycle between feral birds and the ornithophilic mosquito culex univittatus. about 30 avian species have been shown to be involved without mortality. humans, and other mammals, although they may have antibodies, are considered blind-alleys in the transmission cycle except perhaps some dogs. ... | 2001 | 11797772 |
