While we still await a more precise characterization of the France's H5N2 and H5N9 avian flu viruses, the French MOA has announced two addtional outbreaks today, 1 (H5N1) in Bosset (Dordogne) and the other (H5N2) in Doazit (Landes).
This brings to 15 (not including 3 LPAI H5N2 detections) the number of outbreaks reported over the past three weeks in France.
As we've discussed previously, the newly emerged H5N1 virus in France has been described as coming from a (previously rarely reported) LPAI to HPAI mutation (see DEFRA: France’s HPAI H5N1 Another Mutated LPAI Strain), but the origin of the other two newly emerged HPAI strains remains unspecified.
We are assured by the MOA, however, that none of these strains belong to the Eurasian HPAI H5 lineage - making it unlikely that they pose a serious threat to human health.
This is the latest status report from the Ministry of Agriculture.
