The World Health Organization (WHO) declares an end to a hantavirus outbreak linked to a cruise ship, bringing to a close an international public health response that began earlier in the year. Multiple reports state that the outbreak is associated with the MV Hondius and involved 13 people in total—12 confirmed cases and one additional probable case. Three people die among those cases. WHO’s determination is based on the completion of the required quarantine and testing of the remaining affected individual(s), with the final person in the confirmed case group testing negative after finishing the quarantine period. Media accounts describe the situation as ongoing for several months and note that broader monitoring and health surveillance followed the identification of cases, including coordination across countries. Earlier coverage also describes that at one point more than 600 people were under medical surveillance, reflecting the public health measures taken to identify and monitor potentially exposed passengers and contacts. With the outbreak now concluded, the WHO status signals that no further linked cases are expected under the outbreak response framework.
