Influenza A(H1N1) virus infection in humans is frequently reported in people who have direct contact with pig farms. The absence of known exposure to animals in this case justifies specific epidemiological monitoring. However, the fact that this is an isolated case, without severe respiratory symptoms or compatible symptoms, and with no secondary cases identified to date, suggests that the risk to public health is low.

In any case, it is recommended to maintain active epidemiological surveillance and to carry out a genetic comparison with the viruses currently circulating in pig farms in the area, in order to determine the possible origin of the infection and characterise the viral evolution.
