The bird flu virus H5N1 has been detected for the first time outside the US in a cow in the Netherlands. Antibodies against the pathogen were found in the milk of the animal on a farm in the province of Friesland. The Friedrich-Loeffler-Institut in Greifswald confirms that no such case was previously known worldwide.
A Hong Kong poultry stall in Sha Tin’s Wo Che Market was suspended for disinfection after an environmental sample tested positive for the H9 bird flu virus. A two-year-old boy had contracted H9N2 after visiting the market, though shoppers said they were not worried.

Cientistas das universidades de Cambridge e Glasgow mostraram por que muitos vírus de gripe aviária podem continuar a replicar-se a temperaturas semelhantes à febre que tipicamente inibem a gripe humana. Um estudo na Science identifica o gene viral PB1 como crucial para esta tolerância ao calor, levantando preocupações sobre riscos pandémicos se tais genes passarem para estirpes humanas.
