Wu Zunyou said that the survival time of new crown pneumonia on the surface of objects depends on the degree of pollution, as well as the temperature, humidity, light and ultraviolet rays in the environment. In general, the risk of human infection caused by surface contamination of an object is relatively small, but if repeated contact, and do not pay attention to hand hygiene and personal protection, the risk will be significantly increased. Therefore, we conduct regular testing of foreign-related cold chain and foreign-related freight personnel to find infected people in a timely manner. According to the clinical epidemiological analysis of the current cases, the average interval between infections in Omicron was 3 days, which was further reduced than the 4 days of the Delta variant. The Omi clone mutant is about twice as capable of propagating as the Delta mutant, and is stronger. Omi clone infection has atypical symptoms and the entire transmission process is more insidious.
Good habits are still reasonable. Including paying attention to environmental hygiene, scientific and reasonable wearing of masks, often natural ventilation, less gathering, especially in areas with poor natural ventilation or congestion, and public places pay attention to maintaining a one-meter social development distance. Dry cough, remember to cover it with toilet paper or elbow joints when coughing. This good habit is still an important way to suppress the virus, and the same applies to the Omicron variant. The whole inoculation process is still relatively reasonable. According to data from countries around the world, covid-19 vaccines are the most effective way to prevent COVID-19, especially to reduce critical illness and death.
Improving immunity makes sense. It is also a powerful weapon to tackle various viruses, including COVID-19. Pay attention to a reasonable diet, appropriate physical exercise, adequate sleep, especially staying up late, sleeping after 12 o'clock will reduce immunity. At present, the development strategy and countermeasures for epidemic prevention are still reasonable. With the development of the whole society, it is necessary to strengthen the vigilance against the new crown pneumonia, especially the Omicron variant strain, maintain internal prevention and increase, and prevent the epidemic from rebounding again.
