The resurgence of bird flu

This is amazing Highly pathogenic avian influenza has been gaining momentum in Nova Scotia, Newfoundland, Ontario and Quebec since early April. This infectious disease is found in wild birds, but also in poultry houses – in Quebec, three cases were reported in wild birds for the first time.
