The World Health Organisation declares the cruise ship–linked hantavirus outbreak over after the final affected person completes the quarantine period and tests negative. Multiple reports say the outbreak results in 13 total cases connected to the cruise ship incident, with three deaths. One outlet reports that, at the height of response efforts, more than 600 people who were exposed were placed under medical surveillance in four countries. Another report states that there are 12 confirmed cases and that the last of these completes quarantine and tests negative, marking the end of the outbreak under WHO guidance. Authorities monitor exposed passengers and crew through follow-up and quarantine requirements, and the outbreak is considered concluded once testing and quarantine for confirmed cases show no further evidence of infection. The reported cases span several countries due to passenger travel and subsequent contact screening. Overall, the consensus across sources is that WHO’s formal declaration follows negative test results from the final confirmed case and the end of quarantine for that person.
