How does fever work?
Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence.
This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵

Avian-origin influenza A viruses tolerate elevated pyrexic temperatures in mammals
Host body temperature can define a virus’s replicative profile—influenza A viruses (IAVs) adapted to 40° to 42°C in birds are less temperature sensitive in vitro compared with human isolates adapted t...

Highly pathogenic H5N5 avian flu has mostly been detected in wild birds and transmitted from Europe to N. America by pelagic seabirds. Mammals (seals, walrus, cats) have been infected, but this is the 1st documented human case. Some have a PB2-E627K mutation known to facilitate mammalian adaptation.
A case in WA of H5N5 (not H5N1), a strain of avian influenza not seen in humans before:
