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 about being infected if they come into contact with "Yangkang"?
Many infectious disease experts said that if the "positive" people's antigen tests before returning to work are negative, they are no longer contagious. At the same time, they reminded that the time of infection cannot be used to judge whether they are contagious alone. Those "positive" people can do an antigen self-test before returning to work.
"Since almost 10 days ago, my colleagues around me have tested positive one after another. Fewer and fewer colleagues are working, and now they have become the company's 'lone seedling'. Now colleagues are starting to return to work one after another." Mr. Cao from Chaoyang District, Beijing, told the People's Daily Health Client that he was very lucky to advance to the "finals", but after contacting people who had already returned to work and had "sickness", some of them still had cough symptoms, so he was still a little worried.
"Only when an infected person contains the new coronavirus in his body during the infection and onset stages can he infect others." 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 with the People's Daily Health Client on December 25 that after COVID-19 patients recover from treatment, if the antigen self-test is If it is negative, it means that the toxins in the body have been eliminated and there is no replication of virus in the body, so it is no longer contagious. "
For some people who have been infected with the virus, they think they have been infected for more than a week or ten days and now have no symptoms. They should have recovered and are no longer contagious. Sheng Jifang emphasized that everyone's physique, age, and condition are different. Some people's infection takes a long time to become negative, while some people's time is short. You cannot judge whether you have become negative based solely on the time of infection. You should still do an antigen test.
Li Tong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital and a medical expert at Xiaotangshan Fangcang Hospital, previously said in an interview with the People's Daily Health Client, "If you still have cough symptoms, it is recommended that everyone wear a mask when returning to work and when going out to visit relatives and friends, especially those working in important positions such as nursing homes and medical institutions. If you want to visit the elderly, infants and young children, it is best to wait. When it is no less than 10 days from the onset of symptoms and the conditions for turning negative are met, it can be considered that there is basically no problem. "
In terms of personal protection, Sheng Jifang emphasized that people returning to work should insist on wearing masks, washing hands frequently, ventilating frequently, maintaining a safe distance, keeping warm, drinking plenty of water, and keeping nasal mucosa moist, which is still very important to avoid other viral infections.
