Avian influenza is a common influenza virus, influenza A virus is the most susceptible to mutation, while human avian influenza (abbreviated as human avian influenza) is an acute respiratory infectious disease caused by some strains of certain subtypes of avian influenza A virus, and virus gene mutation can infect humans.
The main symptoms after infection are high fever, cough, runny nose and myalgia. Most of them are accompanied by severe pneumonia, and severe cardiac and renal failure leads to death, with a high mortality rate. The disease can be transmitted through digestive tract, respiratory tract, skin injury and conjunctiva, and traffic between people and vehicles is an important factor to spread the disease.
Influenza A is highly pathogenic to human beings and has caused many worldwide pandemics. Avian influenza virus subtypes that can directly infect humans can be found in influenza A virus: A H 1N 1, H5N 1, H7N3, H9N2 and H 10N8. Among them, H 1, H5 and H7 subtypes are highly pathogenic, and H 1N 1, H5N 1 and H7N9 are particularly worthy of attention.
As of March 3 1, 2065438, 3 1 China, more than 127000 confirmed cases of influenza A (H 1N 1) have been reported in 3 1 provinces, including domestic infected cases/kloc. 800 people died.
