Egypt has detected four new cases of avian influenza (bird flu) in poultry, officials have announced.

Three of the bird flu cases were found late last week in so-called “backyard,” or domestically bred, poultry in the Egyptian capital during a surveillance and testing campaign for bird flu. The fourth bird flu case was detected in a village near the southern city of Sohag.

The bird flu cases of the highly pathogenic H5N1 avian influenza virus were the first detected in birds in Egypt in roughly two months. Egypt has had the largest cluster of human bird flu

No human bird flu cases have been reported since May. However, bird flu had infected 14 Egyptians, killing six, between March and May after the bird flu virus first surfaced in Egyptian poultry last February.
