Chinanews.com, Beijing, February 18th (Wei Xianghui) Recently, related reports on "the first local detection of XBB.1.5 in China" have attracted widespread attention.

At the same time, many netizens said on social media that they had started to have a fever again, worrying about whether they would recover.

　　In this regard, Li Tong, chief physician of the Respiratory and Infectious Diseases Department of Beijing You'an Hospital, told Chinanews.com on the 18th that my country's immune barrier is relatively strong at this stage, and a new wave of epidemics is unlikely to break out in the near future.

In response to the new round of fever mentioned by netizens, he said that except for a few people who have not yet passed the test, most of the fever cases have nothing to do with the new crown.

In the future, it is not ruled out that people infected with XBB series strains will appear in more places

　　On February 15 this year, the China Centers for Disease Control and Prevention issued a report stating that since December 2022, a total of 14 local cases of mutant strains of local concern have been found across the country, including one case of XBB.1.5, which is a new case of mutant strains in this cycle.

　　Li Tong once introduced to Chinanews.com that XBB has a stronger immune escape ability, and the proportion of new cases in the United States and other regions is gradually increasing. In the future, it will not be ruled out that people infected with XBB series strains will appear in more places.

　　However, Li Tong once emphasized that my country's immune barrier is relatively strong at this stage, and it is unlikely that a new wave of epidemics will break out in the near future, and sporadic cases are still the main ones. At present, the newly confirmed cases are mainly people who have not been infected. It is very unlikely that the strain will infect twice.

　　He said that the number of people infected with new variant strains has increased, and the risk of secondary infection in the population will increase.

In the face of new mutant strains, the immune barrier protection time of the population will be shortened, but it is not completely ineffective, so the probability of another wave of epidemics in the short term is very small.

Most of the recent fever cases have nothing to do with the new crown

　　Regarding some recent fever cases, Li Tong once believed that, except for a few people who have not yet had a positive infection, most of the fever cases have nothing to do with the new crown.

"Of course, it is not ruled out that people who have been positive in the past 3 months will go to the doctor again because of other diseases, but there is no evidence that it is related to the new coronavirus." He said.

　　Li Tong once introduced that since 2020, Fuyang cases have always existed. Some people are still positive for two or three months, or they are positive again after testing negative.

He said that this group of people is mainly immunocompromised population, which is more common in immunosuppressive drugs used after organ transplantation, AIDS immunocompromised, or immunocompromised population during the stage of tumor radiotherapy and chemotherapy.

　　Li Tong once pointed out that Fuyang and reinfection are two concepts.

Fuyang is the same infection, generally not contagious, and will not cause disease.

"Re-infection and what everyone calls 'Double Ninth Festival' should mean the same thing, that is, re-infection with the virus is usually not the same strain as the previous infection, or after encountering a mutant strain, the risk of re-infection is higher." He said. It is generally believed that those who test positive again within 3 months are more likely to be Fuyang and less likely to be reinfected.

　　Li Tong once also said that people in Fuyang are basically not contagious and have no virus-related symptoms, but they are only found to be positive for nucleic acid or antigen because of other conditions.
