How is avian influenza transmitted?

summary

Every year, almost all places spread avian influenza, mainly related to the migration of migratory birds. Every winter, migratory birds are easy to infect viruses in various places during the migration process, and spread these viruses. Next summer, migratory birds return to the north to breed, which will cause cross infection of viruses in different areas. How is avian influenza transmitted? Let's talk about it

How is avian influenza transmitted?

Avian influenza is mainly transmitted through the air. The virus is transmitted by excreta of diseased birds, blood of corpses, drinking water and environment of organ groups, and eggs, causing environmental pollution. It can also be infected through digestive tract and skin wounds.

Avian influenza is generally not transmitted to people. However, with the change of global ecological environment, avian influenza, which was mainly prevalent in wild birds, occurs frequently in breeding birds. The frequent contact between human and poultry makes the avian influenza virus mutate in human body, constantly adapt, and eventually cause pathogenicity to human.

Early symptoms are very similar to common influenza, mainly manifested as fever, runny nose, nasal congestion, cough, sore throat, headache, general discomfort, some patients may have nausea, abdominal pain, diarrhea and other gastrointestinal symptoms. Most patients have short course of disease, quick recovery, good prognosis and no sequelae. A small number of patients, especially those who are older and not treated in time, will rapidly develop into progressive pneumonia and acute respiratory distress syndrome. If not treated in time, it will lead to death.

matters needing attention

We should improve our immunity, strengthen exercise and ensure adequate nutrition. Infants and young children should be vaccinated with BCG on time to obtain immunity. Secondly, we should pay attention to room ventilation and avoid close contact with the confirmed infectious tuberculosis patients. Thirdly, we should effectively treat diabetes, silicosis, pertussis and other basic diseases that are easy to induce tuberculosis.
