Hantavirus surveillance for South Africa.
South Africa entered the surveillance map via the MV Hondius cluster when the index case's wife disembarked at Saint Helena, traveled via Johannesburg, and died there on 26 April 2026.
Watch status. South Africa is not endemic for any hantavirus species but is currently a focal point of the MV Hondius cluster, with one confirmed death and one critical case linked to imported Andes virus.
The dominant hantavirus species in South Africa is Andes. See the strain reference for detail on transmission, mortality and reservoir biology.
