Health authorities are actively tracking down and monitoring passengers who disembarked from a hantavirus-stricken cruise ship, which has resulted in three deaths. The outbreak is suspected to have originated from a Dutch couple who contracted the virus during a bird-watching trip in Argentina before boarding the ship. On April 24, more than 30 passengers left the vessel at St. Helena without contact tracing, raising concerns about further spread. The World Health Organization (WHO) has stated that the risk to the general public remains low, as hantavirus is primarily spread through inhalation of contaminated rodent droppings. Investigators are focusing their efforts on Ushuaia, Argentina, where the couple traveled prior to the cruise. They plan to analyze local rodents to determine if they carry the Andes virus, the strain involved in this outbreak. Health authorities in various countries are also monitoring individuals who had contact with the passengers, including those who flew from St. Helena to South Africa and beyond. The ship is now en route to Spain's Canary Islands, with over 140 passengers and crew still on board.
