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.
