The survival time of the virus and whether it is airborne remain to be demonstrated. Novel coronaviruses are mainly transmitted by droplets, and transmission is only possible when they are close to the source of infection. The distance of droplet transmission is generally 1-2 meters, and it is relatively safe if a person is 1 meter away from the source of infection, and even safer if he or she is 2 meters away. Sneezing is more distant than talking, but it does not mean that sneezing causes the new coronavirus to float in the air, and it has not been proven that the virus can be transmitted over long distances through the air. But even so, it is important to keep your distance and wear a mask for protection when in contact with people.
