The World Health Organization (WHO) confirms that the hantavirus outbreak among passengers on a cruise ship is caused by the Andes virus strain. Both reports state that WHO’s analysis links the illness to this specific strain, rather than a different hantavirus. The confirmation is presented as a key step in understanding the outbreak’s origin and characteristics, including how the virus spreads and what symptoms and risks affected passengers may face. The reports also indicate that the WHO determination is based on the investigation into cruise ship cases, using the information available to date to identify the responsible virus strain. With the strain confirmed as the Andes virus, public health guidance can be more specifically targeted to the confirmed pathogen. The reporting does not provide additional disputed details such as case counts, locations of exposure, timelines, or severity. It also does not include contrasting interpretations from other agencies. Overall, the sources agree that WHO has identified the Andes hantavirus strain as the cause of the outbreak among cruise ship passengers.
