France Health Min Rist: virus sequencing not yet complete; Tenon Hospital infectious-diseases head says no one can say whether mutation affects transmissibility or severity

Connexion France (May 12 2026, citing French health authorities + Tenon Hospital expert): French Health Minister Stephanie Rist at an afternoon press conference: 'no elements suggesting the circulation of the virus on national territory' and confirmed none of the possible contact cases are showing hantavirus symptoms. The same Connexion France piece notes 'uncertainties remain over how the strain behaves in a European context' and quotes Gilles Pialoux, head of infectious and tropical diseases at Tenon Hospital (Paris): 'No one can say whether this mutation has an impact on transmissibility or severity.' Pialoux is also quoted elsewhere via the same reporting line saying 'We have a new hantavirus every year and constant mutations.' These statements contrast with ECDC's May 12 statement that the cruise-cluster virus is 'similar to Andes viruses already circulating in South America and is not a new variant' - the two framings are not strictly contradictory (ECDC's preliminary genetic analysis can be consistent with French sequencing being incomplete) but the public-facing uncertainty is now on the record.
