Health authorities in Portugal have confirmed that a suspected case of hantavirus infection has tested negative, easing concerns amid ongoing international monitoring of a related cruise ship outbreak.
The case was initially flagged after routine surveillance linked to passengers potentially exposed to the virus aboard the MV Hondius, a cruise vessel that has been at the center of a multi-country health investigation involving confirmed hantavirus infections in several European countries. However, follow-up laboratory testing has now ruled out infection in the suspected individual.
Portugal’s Directorate-General of Health (DGS) has reiterated that the risk to the general population remains very low, and no evidence of community transmission has been detected in the country. Health officials continue to emphasize that all suspected cases in Portugal are being closely monitored in coordination with the European Centre for Disease Prevention and Control (ECDC) and the World Health Organization (WHO).
The wider outbreak, linked to the cruise ship, has involved multiple confirmed cases across Europe, with some passengers developing severe respiratory illness. Despite this, international health agencies have consistently assessed the risk to the general public as low due to the limited and specific transmission conditions of the virus.
Portuguese authorities have also stated that precautionary guidance is in place for healthcare providers, but no additional public health measures are currently necessary.
Officials say surveillance will continue as international contact tracing and monitoring of passengers from the ship progresses.
