Prevention of novel pneumonia requires self-isolation, exercise, and open windows and ventilation because novel coronavirus pneumonia is somewhat self-limiting and there are no specific antiviral drugs available for prevention or treatment. It is recommended that going outside as little as possible will not only reduce the chances of being infected, but will also reduce the chances of coming into contact with or infecting others. You can use 75% medical alcohol to disinfect door handles and other frequently touched areas and objects. Keeping indoor air circulation for 30 minutes once in the morning and once in the evening, drinking more water, strengthening physical exercise, and reducing unnecessary parties and movement of people are more fundamental ways of prevention. If there is any obvious fever or discomfort in the body, etc., go to the local fever clinic for judgment in a timely manner. Content source: Dr. You Lai
