Hantavirus Outbreak on Cruise Ship Prompts Rat Trapping in Argentina

The Story

A cluster of hantavirus cases linked to the cruise ship MV Hondius has resulted in eight reported infections and three deaths, according to the World Health Organization. The WHO assessed the public health risk as low but noted more cases may emerge due to the incubation period. Argentine investigators have begun trapping rodents in forests near Ushuaia, the southernmost city, to search for the source of the outbreak. The virus involved is the Andes virus, which can spread between humans through close and prolonged contact. Health officials are working under the International Health Regulations to coordinate the response and prevent further transmission. WHO has deployed an expert to the ship and shipped 2,500 diagnostic kits to five countries to strengthen testing capacity.
