This page chronicles the implications for Tristan of the outbreak of the Andes variant of hantavirus on the cruise ship MV Hondius in April/May 2026, which resulted in fatalities among the passengers. The ship, an annual visitor and good friend of Tristan, visited the island for three days in mid-April 2026. One islander had returned to the island on the ship from Ushuaia, Argentina, and was hospitalised on Tristan with suspected hantavirus. Four more islanders had travelled on the Hondius to St Helena, where they went into precautionary isolation.
With Tristan's hospital under pressure and with medical supplies running low, the British Government stepped in to provide relief medics and supplies, which arrived via a historic and intrepid airdrop on the 9th May 2026. This episode closed with the WHO declaring the end of the outbreak on the 2nd July 2026 and the departure the day after of the relief medical team from Tristan.
