The causative agent of novel coronavirus pneumonia is the novel coronavirus, and home isolation is encouraged during the outbreak, as long as you do not come into contact with the virus or become contaminated with it, you are unlikely to develop the disease. Avoiding going out and contact as much as possible is the only way to truly prevent the onset of the disease. However, if you have to go out under special circumstances and go to a more complicated environment, such as a shopping mall or hospital, you must take off your outer clothing, wash your hands, and strictly clean and disinfect them when you return home. Outerwear, shoes and hats should be placed separately. When you are outdoors, you should pay attention to avoid crowd gathering places as much as possible, and keep a distance from the people around you to reduce the chance of being contaminated. Be sure to wear good protective equipment, such as wearing a better mask, and can carry out appropriate physical activities in places where the crowd is sparse. Content source: Dr. You Lai
