“Nine cases of hantavirus linked to the MV Hondius cruise ship outbreak have now been confirmed by the World Health Organization (WHO)”

SINGLE SOURCE

While Wikipedia confirms an outbreak on the MV Hondius in April 2026 involving the Andes virus and one death, the specific number of 'nine cases confirmed by the WHO' is not mentioned in the provided evidence. The evidence confirms the event but not the specific count of nine cases.
