The main mode of transmission of novel coronavirus pneumonia is through respiratory droplet transmission. The virus in the lungs can be transmitted to the air through droplets, and if someone is in close contact with the patient, it can be transmitted to the other person’s respiratory tract to get the disease. In this case, it is important to wear a mask to avoid droplet transmission to your own respiratory tract. Droplet transmission does not exceed 2 meters at most, because droplets have a certain volume and fall to the ground quickly under the effect of gravity. In order to protect from being infected, it is best to ensure a certain distance, i.e. more than 1 meter, and to wear a mask during communication with other people. Contact transmission is mainly due to droplets falling on tables, chairs, doors, door handles, other people touching the contaminated items, and hands touching the mouth, eyes, nose, which is contact transmission. Therefore, in order to avoid this, disinfection and hand washing should be done. For items that may be contaminated, you can disinfect them with alcohol, wash your hands, and wash your hands once you have touched these items. Make sure to wash your hands for at least 15-20 seconds under running water, and wash your hands according to the seven-step hand washing method. Content source: Dr. You Lai
