Zhang Boli reminded:
After the "Double Ninth Festival", these people should be careful about the "Double Ninth Festival"
Currently, a large number of people infected with the new coronavirus are gradually becoming "Yangkang", and many people have returned to work one after another. Some people began to take care of their relatives who were infected after being "well". Many people are worried that if the strain of the new coronavirus is different, will they be infected by the new coronavirus again? Zhang Boli, an academician of the Chinese Academy of Engineering, will give you the answer.
Zhang Boli, academician of the Chinese Academy of Engineering. Hao Jie Photo, The rate is mainly related to the level of human immunity, virus strain mutation and personal protection in the later stage. " Zhang Boli said that compared with early mutant strains, the strains of the Omicron family can cause more breakthrough infections and repeated infections, and can escape the antibodies in people who have recovered from the new coronavirus infection.
However, Zhang Boli said that everyone does not need to worry too much. Although there is no evidence from a large sample of people to show the specific time for sustained immunity after infection with the Omicron variant, the human immune system is already functioning after infection with the new coronavirus. Current clinical observations show that the probability of secondary infection with the new coronavirus within 3 to 6 months after infection is still relatively low.
Many people are worried that a second infection with the new coronavirus will worsen symptoms. Zhang Boli said that the situation of a second infection with the new coronavirus varies from person to person. And after secondary infection, the severity of the disease is related to various factors such as the viral infection dose, the pathogenicity of the new coronavirus variant, and personal health status. However, judging from most current reports, because the body has developed immunity , the symptoms of the second infection will generally be milder than the last time.
However, Zhang Boli emphasized that there are also a few studies reporting that compared with patients who have only been infected once, patients who are reinfected have a higher risk of complications, including pulmonary, cardiovascular, diabetes, , gastrointestinal and nervous system complications.
It is recommended that "Yangkang" be vaccinated with the new coronavirus vaccine after 6 months
"Although it is unlikely to be infected with the same new coronavirus variant strain again in a short period of time, people with poor immunity are prone to repeated infections, including the elderly Infants, young children, people with underlying diseases, and people with immune deficiencies are at risk of secondary infection in the short term, especially when faced with new mutant strains. "Zhang Boli said that people in high-risk positions such as doctors and nurses are in work environments with high risk of transmission, are exposed to many mutant strains, work intensively, and are at high risk of secondary infection.
"It is mainly a re-infection of the new coronavirus mutant strain, so personal protection must be continued even after the infection turns negative." Zhang Boli emphasized that "Yangkang" can be vaccinated with the new coronavirus vaccine after 6 months. It is best to adopt a sequential strategy and inject heterogeneous vaccines to strengthen the immune barrier .
For those who have recovered from new coronavirus , the best way to prevent secondary infection during the epidemic is to implement protective measures, including wearing masks, paying attention to hand hygiene, taking breaks, ventilating frequently, maintaining social distance, etc. Especially for the elderly and children with "positive to negative" patients, they should keep warm, gather as little as possible, ensure good hygiene habits, pay attention to nutritious diet, enhance immunity and reduce the risk of reinfection.
Will you be infected if you work with "Yangkang"?
Recently, many people infected with the new coronavirus have gradually recovered after being treated at home, but some are still infected. These people are called by netizens as having entered the "finals" of epidemic prevention. Are these people worried that they will be infected if they come into contact with "Yangkang" people?
Many infectious disease experts said that if the "Yangkang" people's several antigen tests before returning to work are negative, they are no longer contagious. At the same time, they are reminded that the time of infection cannot be used to judge whether they are contagious. People who have "Yangkang" can do an antigen self-test before returning to work.
“An infected person can infect other people only if he or she contains the new coronavirus in the body during the infection and onset stages.Professor Sheng Jifang, deputy director of the State Key Laboratory of Diagnosis and Treatment of Infectious Diseases and director of the Department of Infectious Diseases at the First Affiliated Hospital of Zhejiang University School of Medicine, said in an interview, "After COVID-19 patients recover from treatment, if the antigen self-test is negative, it means that the toxins in the body have been eliminated, and there is no replication of the virus in the body, so they are no longer contagious. "
In terms of personal protection, Sheng Jifang emphasized that "Yangkang" workers should insist on wearing masks, washing hands frequently, ventilating frequently, etc. when returning to work, maintaining a safe distance, and keeping warm, drinking more water, and keeping nasal mucosa moist, which is still very important to avoid other viral infections.
"Yangkang"
Let's look at the answers to these concerns after "Yangkang"
↓
Do I still need to take personal protection after "Yangkang"? What should I do if I have poor appetite in the early stages of recovery? Can I exercise after "Yangkang"? Regarding the 8 questions that everyone is most concerned about, let’s take a look at the answers from the Shanghai Health Promotion Center ↓
1. Do I still need to take personal protection after "Yangkang"?
Winter is the season with the highest incidence of respiratory diseases, and "yangkang" does not mean that you will not be infected again or suffer from other respiratory diseases. Therefore, try to reduce the number of people visiting after "Yangkang" In densely populated places, do not lower prevention and control standards, continue to adhere to good habits such as wearing masks, washing hands frequently, maintaining social distance, opening windows for ventilation, and pay attention to coughing and sneezing etiquette.

2. Do you need to take supplements if you feel "yangkang"?
During the infection period, you may experience loss of appetite, diarrhea, bloating, and reduced sense of taste and smell.
