NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsEpidemiology: Key predictors of avian flu outbreaks in Europe identified
Several local factors — including the minimum temperature reached in autumn, the water level in lakes and ponds in winter, and the presence of mute swans — could be key for predicting the potential of an outbreak of highly pathogenic avian flu (HPAI) occurring in Europe.

NewsBovine H5N1 influenza from infected worker transmissible and lethal in animal models
A highly pathogenic avian influenza H5N1 virus, isolated from the eye of a farm worker who became infected through contact with dairy cows, was lethal in mice and ferrets infected in a high-containment laboratory environment.

NewsReceptors make dairy cows a prime target for influenza
Researchers who examined mammary gland samples from two cows infected with highly pathogenic avian influenza found a rich supply of sialic acid, which could shed light on how the virus attaches to hosts and help develop measures to slow the spread.
