Abstract:
We investigated West Nile virus (WNV) as a possible
disease etiology in persons hospitalized in South Africa. Of
206 specimens tested, 36 had WNV neutralizing antibodies,
signifi cantly more than in similar earlier serosurveys. Seven
probable acute WNV cases were identifi ed, suggesting
WNV may be overlooked as an etiology of severe disease
in South Africa.
