Global health attention is focused on the MV Hondius, where a hantavirus outbreak has triggered an international response stretching from Tenerife to Britain and Australia. As the ship prepares to dock in the Canary Islands, the WHO’s Tedros Adhanom Ghebreyesus has urged residents to stay calm, saying the risk to the public is low and not comparable to Covid-19, even as Spain coordinates disembarkation and new suspected linked cases emerge in Spain and on remote Tristan da Cunha. The UK is preparing to isolate returning British passengers and crew at Arrowe Park hospital in Merseyside, while Australia is arranging to repatriate five people from the vessel. In a very different public-health story, California is moving to ease pressure on new parents with “Golden State Start,” a first-in-the-US program that will send families home from participating hospitals with 400 free diapers for every newborn.
