Xinhua News Agency, Beijing, February 21 (Reporter Li Wen) Popova, director of the Consumer Rights Protection and Public Welfare Supervision Bureau of the Russian Federation, said on the 20th that seven people in Russia were found to be infected with the H5N8 avian influenza virus, which is the first human infection in the world.

H5N8

In December last year, a bird flu outbreak broke out in a farm in southern Russia

H5N8 avian influenza virus is a highly contagious virus among birds, which was first discovered in the world in 2014

The analysis report pointed out that wild birds may face the risk of infection or transmission of H5N8 avian influenza virus during their migration

type of inheritance

Influenza viruses can be divided into three types: A, B, and

For example, both H7N9 and H5N1 belong to influenza A viruses, but there are obvious differences

The acute respiratory infectious disease caused by some subtypes of avian influenza virus is called "human avian influenza".

WHO influenza experts said that the avian influenza virus is constantly mutating, and the avian influenza virus circulating in wild birds and poultry has reached an unprecedented diversity and geographical distribution; avian influenza viruses are usually transmitted among birds, poultry and other animals.

How to prevent

The bird flu epidemic has made people "smell the chicken"

Regarding the first question, Bernard Valette, the former director-general of the World Organization for Animal Health, believes that as long as it is heated above 70 degrees Celsius, the bird flu virus will die.

WHO experts said that in areas with bird flu outbreaks, meat products are safe to eat as long as they are properly cooked and handled during the preparation process, but eating raw meat and undercooked meat products is a high-risk behavior.

John Macaulay, director of the World Influenza Center of the National Institute of Medical Research in the United Kingdom, said that because the bird flu virus is very sensitive to outside temperature, the normal cooking of poultry ingredients is enough to kill the bird flu virus they may carry, so people are more sensitive to poultry and other related foods.

Regarding how to contact and raise animals, the WHO reminds: In areas with cases of avian influenza, if you need to enter the local live poultry market, you should avoid direct contact with live animals and surfaces that have been touched by animals; if there are domestic pigs, chickens and other animals, it should be ensured that children do not come into contact with such sick or dead animals, and try to isolate different types of animals; after animals become sick or dead, they should report to the relevant local authorities immediately; they should not be slaughtered or eaten.
