Swine flu

Influenza viruses that emerge and circulate in pigs all have zoonotic potential, meaning they can infect humans, and sporadic cases are regularly detected. No recent cases of human-to-human transmission of these viruses have been documented.

Our missions

  • Epidemiological surveillance, validation of case classification in cases of suspected human infection with a swine influenza virus in France, confirmation of cases in collaboration with the National Reference Center for Respiratory Infections, and participation in investigations of confirmed cases, in collaboration with the Regional Health Agency (ARS).

  • Providing information to public authorities on the epidemiological situation regarding influenza viruses with zoonotic potential
