What we know about hantavirus cases tied to deadly cruise ship outbreak

TL;DR

  • Nine confirmed or suspected hantavirus cases, including three deaths, are linked to the M/V Hondius cruise ship.
  • The outbreak involves the Andes virus strain, which is unique in its ability to spread between people through prolonged close contact.
  • Investigations, contact tracing, and isolation protocols are underway in multiple countries as passengers have disembarked.
  • The first suspected cases were a Dutch couple who had traveled in South America prior to the cruise.
  • A British passenger was hospitalized in South Africa with confirmed Andes virus infection and is improving.
  • A German woman died aboard the ship, and three individuals (a Dutch passenger, a British crew member, and a German passenger) were evacuated to the Netherlands.
  • A Swiss man tested positive for the Andes virus after disembarking in Saint Helena, and his wife is self-isolating.
  • A suspected case is being monitored on Tristan da Cunha, a remote British island.
  • The WHO is coordinating with at least 12 countries to monitor returning citizens, including the US, Canada, Germany, and the UK.
