Annual influenza vaccination is the most effective measure to prevent influenza, and maintaining good personal hygiene habits is an important means to prevent respiratory infections such as influenza. Family members should try to avoid contact with each other if there are influenza patients, especially if there are elderly people and chronic disease patients in the family to avoid spreading. Influenza patients should avoid crowded areas to reduce the spread of the disease, and during the high season of the disease, they can protect themselves by wearing masks. During the flu season, elderly people and people with chronic diseases should go out less, avoid going to crowded areas, avoid contact with patients with respiratory infections, wash their hands frequently, and keep the environment clean and ventilated to avoid infection.
