Spain has alerted the World Health Organization of what it believes to be a person-to-person transmission of the swine flu virus in its A(H1N1)v variant, a spokesperson for health authorities in the Catalonia region confirmed to Reuters on Friday (February 27, 2026).
In a later statement, the Catalan health department said the risk assessment for the population was considered “very low”.
The person infected did not exhibit flu-like respiratory symptoms, it said, and tests on direct contacts showed the virus had not retransmitted.

An earlier report by newspaper El Pais citing Catalan health department sources said the patient — who has since recovered — had no contact with pigs or pig farms, leading experts to conclude it was a human-to-human transmission of the pathogen.
