As for the prevention of influenza, first, go to less crowded places and confined spaces, do not stay in them for too long, wear a mask when you go out, and wash your hands with standardized flowing water after returning home, and stay in relevant places in the epidemic area. It is necessary to promptly disinfect the contact items, and the home must be more ventilated. Compared to disinfection and ventilation, ventilation in the home is the first choice, and only good air circulation is the fundamental.
