avian influenza

Asian H5N1 was first detected in humans in 1997 during a poultry outbreak in Hong Kong and has since been detected in poultry and wild birds in more. Avian influenza is in no way connected to the COVID-19 pandemic which is caused by the SARS-CoV-2 virus and is not carried in poultry.

The agency says Avian Influenza often called bird flu can affect several species of food-producing birds including chickens turkeys quails and guinea fowl as well as pet and wild birds.

. An influenza pandemic is a global outbreak of a new influenza A virus. H5 N2 is a subtype of the species Influenzavirus A avian influenza virus or bird flu virus. Avian influenza was confirmed in a backyard flock on the Isle of Anglesey on 25 November 2021.

Avian influenza is mainly found in birds but under certain circumstances infections can also occur in humans even though the risk is generally very low. Avian influenza is a viral infection found in domestic poultry and a wide range of other birds. Wild waterfowl and shorebirds are often asymptomatic carriers.

In poultry low pathogenicity strains typically cause respiratory signs. Ongoing avian influenza virus spill-overs into human cases suggest that zoonotic bird flu is a continued threat to human health. Affected birds usually do not appear ill and the disease is often mild as.

The United States is NOT currently experiencing an influenza pandemic. On March 5 2017 USDA confirmed highly pathogenic avian influenza HPAI H7 in a commercial poultry flock along the Mississippi Flyway. This HPAI H7 strain is of North American wild bird origin.

Asian highly pathogenic avian influenza HPAI AH5N1 virus occurs mainly in birds and is highly contagious among them. High pathogenicity strains may cause widespread organ failure and sudden high mortality. The virus was first detected in 1996 in geese in China.

And on March 7 2017 USDAs National Veterinary Services Laboratories NVSL confirmed the full subtype of this HPAI H7 as North American wild bird lineage H7N9 HPAI. The subtype infects a wide variety of birds including chickens ducks turkeys falcons and ostriches. Following successful completion of disease control activities and surveillance within the zone on 27.

However the apparent success of the H7N9 vaccination programme in China suggests that it is possible to control virus circulation in domestic birds and thus vastly reduce the number of human infections and the risk. HPAI Asian H5N1 is especially deadly for poultry. Following further testing this was confirmed as highly pathogenic avian influenza on 26 November 2021.

Avian influenza is an infectious viral disease in birds including domestic poultry. Highly pathogenic avian influenza can cause severe illness and death in birds. This report by The Canadian Press was first published Dec.

Pandemics happen when new novel influenza A viruses emerge which are able to infect people easily and spread from person to person in an efficient and sustained way. The governments outbreak assessment following recent.
