Rumor identification: The survival time of the virus and whether it is airborne are yet to be proven. Rumor Analysis: 1. Viruses sink quickly after coming out of the body and do not float in the air. In other words, the virus will not be separated from the carrier, such as blood, body fluids, saliva, droplets and other independent floating. According to the current data analysis, the new coronavirus is mainly spread through droplet transmission, usually droplet transmission is only realized when close contact with the source of infection, it is recommended to maintain a distance of more than 1 meter when talking. 2, the new coronavirus in a dry environment, survival time is only 48 hours, after 2 hours in the air, the activity is significantly reduced. Some studies show that at a temperature of 22℃-25℃ and a relative humidity of 40%-50%, the virus can survive on the surface of smooth objects for a day, or even 5 days and still remain alive. However, at higher temperatures and higher relative humidity, the virus will rapidly lose its ability to survive. Special Note: Although the virus has a certain survival time, the new coronavirus can be effectively inactivated by heating at 56°C for 30 minutes or by irradiation with a UV lamp for 30 minutes. In addition, the most important measures to prevent infection are wearing a mask, washing hands regularly, enhancing ventilation, covering the mouth and nose when coughing and sneezing, and visiting crowded places less frequently. Symptoms such as fever, malaise and dry cough after contact with a confirmed and suspected patient require prompt medical attention.
