What is H5N8 avian influenza?
H5N8 avian influenza virus is a highly infectious virus between poultry, which was first discovered worldwide in 2014. Japan, Kazakhstan, Saudi Arabia, Israel, Namibia, India, the United States and other countries have found the H5N8 avian influenza virus. In 2016, H5N8 avian influenza outbreaks occurred in many European countries, causing a large number of poultry and wild birds to die.
The analysis report pointed out that wild migratory birds carrying the H5N8 avian influenza virus may cause fodder from poultry farms to be contaminated with the virus. In addition, vehicles, equipment, pollutants, living animals and animal products contaminated with the H5N8 avian influenza virus may also spread the virus.
What happens if people are infected with avian influenza?
So far, the medical community has found that more than one bird flu virus can be transmitted to humans. Acute respiratory infectious diseases caused by certain subtypes of avian influenza virus are called “human avian influenza”. At present, the subtypes of avian influenza virus that infect humans are mainly H5, H7 and H9.
WHO influenza experts say that the avian influenza virus is constantly mutating, and the avian influenza virus transmitted in wild birds and poultry has reached unprecedented diversity and geographical distribution. Avian influenza viruses are usually transmitted among birds, poultry and other animals, but this virus also infects humans from time to time, such as H5 N1, H7N9 and H5N6 avian influenza viruses.
Patients generally show flu-like symptoms, such as fever, cough, oligophlegm, which can be accompanied by headache, muscle soreness, diarrhea and other systemic symptoms. They can be transmitted through the respiratory tract or in close contact with the secretions and excreta of infected birds, or infected by contact with the environment contaminated by the avian influenza virus.
