, Beijing, February 8 (Wei Xianghui) Recently, the question of "Where did the new crown virus go" has aroused widespread discussion.

The Centers for Disease Control and Prevention of many provinces and cities have issued reminders that cases are currently sporadic in many places, and no new mutant strains have been detected.

At the same time, as the weather gets warmer, some netizens questioned-what changes will the new crown virus have?

After entering the spring and summer season, will the new crown virus disappear?

How do you view the sporadic status of the current cases?

  According to the People's Daily Health Times client report, recently, everyone feels that there are very few people infected with the new crown around them.

The Centers for Disease Control and Prevention of Beijing, Hubei, Sichuan and many other provinces and cities have issued the latest reminders that cases are currently sporadic in many places, and no new mutant strains have been detected.

  In this regard, Li Tong, chief physician of the Respiratory and Infectious Diseases Department of Beijing You'an Hospital, explained to that the sporadic cases are due to the fact that more than 80% of people in most areas have been infected and formed an immune barrier in the past one or two months.

He said that there will not be a large number of infections similar to the previous ones in a short period of time.

However, since there are still a small number of people who are not infected, this distribution may lead to the next round of outbreaks in the future.

What factors affect reinfection?

  Li Tong once said that the spread of the virus requires susceptible people, and once the antibody level of everyone is low, it may trigger the next round.

If the virus does not mutate significantly, the antibodies produced by the previous infection can protect it for more than half a year, and the next round of infection may be half a year later.

  Lu Mengji, a professor at the Institute of Virology at the University of Essen in Germany, believes that the subsequent transmission of the new coronavirus in China may fluctuate, and the time of emergence and the spread of the virus will be affected by the emergence of new strains, climate change, and large-scale crowd movements (such as Labor Day in May). tourism peak) and so on.

How to deal with the decline of antibody levels in the population?

  Li Tong once introduced that even if the antibody level drops, because everyone is not synchronized, some people may drop quickly, while others may drop slowly, and the protective effect lasts for a long time. Therefore, in the next round, some people may be infected first, and some people will be infected later, and the epidemic peaks. It will not come so fast and violently, and there will no longer be a large number of infections in a short period of time.

  Li Tong once believed that people with low immunity and no vaccinations may be the earlier group in the next round of epidemics, while people who have been infected, especially those who have been vaccinated, will have a higher chance of death on the basis of vaccination. Infection is called breakthrough infection. Even if these people are infected for the second time or for the third time, the risk of becoming a severe or critical case will be relatively small.

Will the new crown virus disappear?

  Lu Mengji told that some data recently released by the China Centers for Disease Control and Prevention suggest that the new crown virus has not disappeared, and the alleviation of the current epidemic infection situation cannot be regarded as the end.

"It's a misplaced perception," he said.

  Li Tong once believed that at present, the new crown virus is unlikely to disappear completely like SARS in 2003.

He explained that the global epidemic situation of the new crown is not synchronized. In some places, there are very few new cases now, in some places it continues to exist, and in many places there are repeated peaks of the epidemic.

There are still infected people in society, and everyone is at risk of reinfection.

He judged that the new coronavirus infection may have stages like influenza and will not disappear completely.

  "In general, the people who need key protection in the future are the elderly, those with low immunity, and those with underlying diseases." Li Tong once suggested that on the one hand, we should insist on wearing masks, wash our hands frequently, open windows for ventilation, and maintain social distance.

On the other hand, the level of protection can be increased by revaccination.
