Emerg Infect Dis. 2021 Dec;27(12):3159-3162. doi: 10.3201/eid2712.210643.

Abstract

We detected Rift Valley fever virus (RVFV) IgM and IgG in human serum samples collected during 2018-2019 in northern KwaZulu-Natal Province, South Africa. Our results show recent RVFV circulation and likely RVFV endemicity in this tropical coastal plain region of South Africa in the absence of apparent clinical disease.
