Hantavirus Tracker 2026 — Live MV Hondius Case Count | HantaCount

Q: How many hantavirus cases are there in South Africa?

As of 2026-05-08, South Africa has reported 1 confirmed or suspected case of Andes hantavirus linked to the 2026 MV Hondius outbreak, with 1 death. Counts come from WHO Disease Outbreak News, ECDC threat assessments, and South Africa's national health authority.

Q: Is hantavirus endemic in South Africa?

The 2026 cluster in South Africa is import-related: cases trace back to MV Hondius passengers, crew, or their household contacts. Whether hantavirus circulates endemically in local rodent populations of South Africa is a separate epidemiological question — consult the country's public health authority for endemic surveillance.

Q: What should travellers to or from South Africa do about hantavirus?

Travellers who were on MV Hondius or in close contact with a returning passenger should monitor for fever and respiratory symptoms for 42 days post-exposure. Contact the local health line if symptoms develop. In South Africa, public health is coordinated by National Institute for Communicable Diseases (NICD). See https://hantacount.com/en/countries/za for live counts and the latest official guidance.

Q: How is hantavirus transmitted in South Africa?

Andes virus (ANDV) is the only hantavirus with documented person-to-person transmission, but it requires close, prolonged contact — typically household members or healthcare workers without PPE. Most South Africa cases are returning MV Hondius travellers or their close contacts. Casual transmission (transit, shops, schools) has not been documented for ANDV.

Q: Is there a hantavirus vaccine available in South Africa?

There is no licensed hantavirus vaccine available in any country as of 2026. Treatment is supportive — early intensive care including extracorporeal membrane oxygenation (ECMO) where available significantly improves outcomes. Prevention focuses on rodent control and avoidance of contaminated environments.

Country note

Death 2: Dutch national hospitalised at a Johannesburg hospital, died 26 April. Counted under ZA (location of death and hospitalisation). One further exposed contact identified locally, currently asymptomatic.

Context

The 2026 outbreak is caused by Andes virus (ANDV), the only hantavirus with documented person-to-person transmission. The index event is a cluster aboard the Dutch-flagged cruise ship MV Hondius. South Africa cases are either:

Returning passengers or crew of the MV Hondius
Household or close-contact cases of returning travellers
Suspected pre-cruise exposures (rare, currently under investigation)

The country's national focal point reports cases up to WHO and ECDC; we update from those publications.
