Will the new coronavirus exist for a long time? Desheng answers for you

Recently, the news of Urumqi’s closure of the city was swept away, and Urumqi, which had 40 million people, was ordered to blockade again. Some time ago, an epidemic was diagnosed in Beijing, and the epidemic was controlled within a short period of time. According to news, Beijing has seen 0 new additions in 11 days, and the control capability is very good. According to news at noon on the 17th, the official website of Tianshan in Xinjiang announced that the number of confirmed cases in Urumqi has increased again. According to the latest report of the Health Commission of the Autonomous Region, from 0:00 on July 16 to 12:00 on the 17th, Xinjiang (including the Corps) added 5 newly diagnosed cases and 8 asymptomatic infections, all in Urumqi. As of 12:00 on the 17th, Xinjiang (including the Corps) had 6 confirmed cases and 11 asymptomatic infections, all in Urumqi. There are currently 135 people under medical observation. In view of the continuous phenomenon of the new coronavirus, will the virus exist for a long time? Next, Desheng will answer for you.

The core material of nucleic acid detection-Virus Transport Media

Question: There are some asymptomatic infections around us. Some cases have an incubation period of more than 14 days. Some people have been retested after being discharged and found positive. In addition, some people have a negative throat swab test, but there are still in the stool Keep the virus. How should we interpret a situation like this now?

Answer: We now use a throat swab test (negative) as a standard, but some patients still have virus fragments detected in the feces, not live viruses have been detected. These are two different things. In addition, there are a small number of patients who have been re-examined after being discharged from the hospital and the calculated fragments are found to be positive. This is not surprising to me because they need to be isolated for two weeks after being discharged from the hospital, and the re-examination will continue after the end.

Q: Is this a special case?

Answer: A few, can not be said to be a case. Our current discharge standards: throat swabs are negative twice, there are no symptoms, the body temperature is normal, and the CT is normal, then you can be discharged from the hospital and be isolated for another two weeks. If anal swabs are required to be normal, then our patients will have a backlog and the bed will not be able to turn over! Therefore, we still need to observe closely and implement a hierarchical management of all patients.

Question: On July 20, Beijing lowered its emergency warning and adjusted the second-level response to the third-level response. Do you think this notice is reasonable? What is the basis for Beijing to lower the epidemic warning?

Answer: I think it is appropriate. On the morning of the 18th, the last three high-risk patients recovered and were discharged, and Beijing high-risk patients were cleared. Beijing has not reported newly confirmed local cases for 13 consecutive days, which is a prerequisite. The other is that the masses' awareness of prevention and control has been greatly strengthened. Therefore, it is not appropriate to adopt a secondary response. It is more appropriate to adopt a hierarchical, zoning and classification method for epidemic prevention, which is beneficial to the development of production.

Q: Is it possible that the new coronavirus will exist for a long time like the flu?

Answer: SARS has appeared sporadically in 17 years, but no climate has formed. Will COVID-19 exist for a long time in the future, but will not form an outbreak situation? Also a possibility. The key is to control it to the minimum. I don't think it will be like flu. Flu occurs every year. This possibility should be less.

Nucleic acid testing is important before vaccines are successfully developed

The epidemic is still spreading, and a vaccine has not yet been developed. To control the spread of the epidemic, nucleic acid testing is still an important presence. Although nucleic acid testing is very helpful, more importantly, we should take the initiative to protect it. The WHO mentioned in its COVID-19 prevention guidelines updated in June that the public needs to maintain basic hand and respiratory hygiene, avoid touching the mouth and nose, and eat and drink safely to avoid contracting or spreading the virus; avoid going to crowded places and try It is possible to avoid close contact with anyone showing symptoms of respiratory diseases and keep a distance of more than 1 meter from them. I hope that countries that have not been able to control the epidemic will learn about epidemic prevention and control, examine their own problems, and make active and effective decisions.
