Authorities in Germany have today announced detection of H5N1 avian influenza in a domestic cat. The cat was found dead over the weekend on the northern island of Ruegen. Since mid-February, more than 100 wild birds have died on the island, and tests have confirmed H5N1 infection in several.

There is no present evidence that domestic cats play a role in the transmission cycle of H5N1 viruses. To date, no human case has been linked to exposure to a diseased cat. No outbreaks in domestic cats have been reported.

Unlike the case in domestic and wild birds, there is no evidence that domestic cats are a reservoir of the virus. All available evidence indicates that cat infections occur in association with H5N1 outbreaks in domestic or wild birds.
