In late December, a sick cat in the Deux-Sèvres département tested positive for the highly pathogenic avian influenza virus H5N1. ANSES was actively involved in the investigation of this case, which led to a nearby duck farm being identified as the source of the cat's contamination. The increase in such viral transfers from birds to mammals in different countries calls for vigilance, as they could facilitate the possible transfer to humans.

ANSES's Sophia Antipolis Laboratory has participated in a vast genetic analysis of strains of Coxiella burnetii, the bacterium responsible for Q fever, a disease that can be transmitted to humans. This collaboration between animal and human disease specialists, on which a paper was published in late 2022, is the first step in a One Health project on this zoonosis.

Once a home is infested with bed bugs, it is difficult to get rid of them. Sometimes, faced with the tenacity of these parasites, people turn to insecticides. However, their use is not without risk: more than 1000 cases of poisoning due to these chemicals, some serious, were recorded between 2007 and 2021. To eradicate bed bugs, you should therefore initially favour non-chemical means.
