The new coronavirus can be transmitted by droplets, and its transmission distance is usually within 1 meter, beyond which the possibility of being infected is relatively small.
The new coronavirus has a diameter of about 60~140nm, is round or oval in shape, and is mainly transmitted by droplet. It can attach to dust or surfaces, or form aerosols that can be spread by contact with others.
A person infected with Neo-Crown virus can spread droplets containing Neo-Crown virus into the air by talking loudly, coughing, sneezing, etc. Healthy people will be at risk of being infected if they inhale the droplets. Therefore, during the new crown epidemic, in addition to wearing qualified masks, it is best to maintain a distance of more than 1 meter from others when traveling.
