Influenza A, or influenza, is a respiratory-transmitted infectious disease that can be self-isolated and well-protected. Influenza is a respiratory infectious disease caused by viral infection, transmitted by droplets, through direct contact with mucous membranes such as the mouth and nose or indirectly infected (e.g., by contact with objects infected with the virus). It spreads easily in crowded or poorly ventilated rooms, and the population is generally susceptible. A small number of influenza A cases can develop into serious illnesses, with severe pneumonia, myocarditis and even life-threatening illnesses. Therefore, you can isolate yourself and take good daily protection, especially if you have children or elderly people at home with poor immunity. During the influenza epidemic, we should pay attention to the ventilation and disinfection of the environment, pay attention to personal hygiene, avoid going to densely populated public places, wear a mask when going out, and actively receive influenza vaccination. If you are suffering from influenza A, you need to consult a doctor in time and follow the doctor’s instructions for reasonable treatment.
