The new coronavirus has become particularly cunning now and is hiding deeper. pharyngeal swab cannot be detected. It is possible that some patients have nucleic acid test , and the upper respiratory tract pharyngeal swab and nasopharyngeal swab cannot be detected. However, there are still certain viral infection problems in the lungs.
Moreover, the new coronavirus lasts for a long time. It may be possible that after the isolation is released, through sputum and other behaviors, will bring the virus into the respiratory tract, which will cause the problem of re-positivity after testing. Why does
01
have re-positive situation?
In fact, there are many cases of re-positive new coronavirus cases, , so why does this phenomenon occur?

Is there any contagiousness in the new coronavirus infected person after "re-positive"? Zhong Nanshan's research and answers questions, suggesting to understand
Academician Zhong Nanshan said that we have no way of knowing the occurrence of new coronary pneumonia at all, and we can only understand it while developing, but the rules of microbial infection are almost the same.
Academician Zhong Nanshan believes that discharged patients generally will not be infected with again because sufficient antibodies have appeared in the body.
, led by Academician Zhong Nanshan, the research results published in the National Science Review show that patients with ulcers do not show any aggravated clinical symptoms, and does not need to receive relevant hospitalization.
has basically not seen such a problem so far. The active hardness has not been found through the P3 laboratory research, so the re-positive situation should be the residual of the nucleic acid fragment, and there will be no contagious problems.
03
Why is the new coronavirus difficult to eliminate?
Virus can be said to be the culprit of some of the most deadly and dangerous diseases in the world, such as flu , smallpox, rabies , Ebola. To the current new coronavirus, are all caused by the virus Virus.
experts compared smallpox and polio and found that the eradication of the new coronavirus is extremely difficult. viral pneumonia can lead to such serious consequences. In fact, there are two key reasons:
- First, there is no specific medicine;
- Secondly, the body's self-defense ability has been reduced.
04
How to deal with those who re-positively?
Because most patients with re-positive positive do not have respiratory tract and fever, cough and other clinical symptoms, they should be isolated, reviewed for nucleic acid, blood routine , CT imaging and other corresponding indicators. can only be discharged from the hospital after 14 days of isolation after the nucleic acid turns negative.
There are also relevant experts who suggest that one month's health status monitoring can be conducted after discharge, during which time, therapeutic Chinese medicine can be taken for 1 to 2 weeks. can reduce the spread of the disease and promote later rehabilitation problems.
The latest ninth edition of the "New Coronavirus Pneumonia Prevention and Control Plan" proposes that for epidemic prevention, those discharged from hospital need to continue to undergo a home health test for up to 7 days.
05
At what temperature can the new coronavirus die completely?
A scientific team from the University of Provence, France once discovered that the new coronavirus can be completely killed within 15 minutes under the high temperature of 92℃.
During the experiment, researchers found that the new coronavirus can still survive for an hour at a high temperature of 60℃, and some virus strains can still reproduce in this environment.
After the researchers heated the environmental sample to 92°C, the new coronavirus was completely eliminated for 15 minutes.
06
Prevent the new crown and improve immunity
Maintain regular and adequate sleep
High-quality sleep can promote the human body to produce more sleep factors. Sleep factors can promote the increase of white blood cells , and at the same time strengthen the liver's detoxification ability , so as to eliminate bacteria and viruses that invade the human body.
Therefore, high-quality sleep can help improve human immunity. We recommend that everyone maintain regular and adequate sleep, so that they can promote good health.
Healthy diet
We often say "food is the most important thing for people". Especially in the special period of fighting viruses, everyone should maintain a balanced diet to provide sufficient material guarantee for the normal operation of the immune system.
, and tens of billions of immune cells are produced in the body every day. The raw materials needed to produce these cells need to be obtained through people's diet, so needs the supply of vitamins, minerals and energy. A healthy diet is a necessary condition for improving immunity.
Adjust exercise
If you want to improve your immunity, you cannot ignore proper exercise and exercise. You can do some medium-intensity whole-body exercise , such as aerobics , fitness qigong , yoga, running, swimming, etc.
In addition, exercise also has a positive impact on the psychology, which helps relieve bad emotions such as irritability, anxiety, depression, and panic.
Conclusion: A cruel epidemic has upended the world. We, who are at the center of the vortex, should look at this problem correctly and reasonably, and should also look at those compatriots who have been infected with the new crown normally. They are just patients, and even if they are rich, they cannot face " social death " and cannot discriminate or criticize them.
