As the mutated strain of the new coronavirus continues to evolve, the number of confirmed cases and deaths of new coronavirus pneumonia in many countries around the world has rebounded again recently. More and more patients in the United States and other countries are troubled by the "sequelae of new crown" known as the "long-term new crown".
Chinese Center for Disease Control and Prevention chief epidemiology expert Wu Zunyou analyzed at the joint prevention and control mechanism of the State Council on October 13 that in general, people who have been vaccinated have the risk of sequelae after infection with new crown , which is much lower than those who have not been vaccinated.
Jin Dongyan, professor and virus expert at the School of Biomedicine of the University of Hong Kong, said in an interview with the Health Times reporter on November 3, "At present, the scientific community has different definitions of the sequelae of new coronavirus, and there are no specific detection methods or diagnostic indicators. All the information about the sequelae of new coronavirus that people can obtain comes from the self-report of the infected person, which makes the results lack an objective measurement standard."

Jin Dongyan further explained, " World Health Organization believes that only those who still exist after being infected and last at least 2 months can be called the sequelae of the new crown. US CDCh believes that the relevant symptoms that still appear, recur or exist one month after being infected can be called the sequelae of the new crown."
"I only recovered my sense of taste and smell two weeks after the new crown turned negative. Before I felt like In a state of cold. "A recovery from the new crown in France told the Health Times reporter, "It has been three and a half months since the negative trend. After getting the new crown, the body is more prone to fatigue, but you can feel that you are gradually recovering."
Jin Dongyan said, "Most of the symptoms of the sequelae of the new crown are short-term and mild. Not only that, most of these symptoms are also related to mental health and mental health, the most common ones include fatigue, headache, insomnia, and anxiety. , etc. "
" Long-term symptoms are not unique to the new crown. After the influenza A pandemic in 1918, the SARS outbreak in 2003, and the Ebola outbreak in West Africa in 2014, patients have had sequelae after infection. "Jin Dongyan said, "Compared with the delta variant strain and the original strain, the proportion of sequelae of new crown during the pandemic stage of Omickron has been greatly reduced. The chances of sequelae of new crown in asymptomatic infected persons have been slim, The proportion of people with mild symptoms who have the sequelae of new coronavirus is far lower than those who have the severe symptoms. "
" At present, scientists from various countries are very concerned about and worried about the sequelae of new coronavirus infection." Liang Wannian, head of the expert group of the National Health Commission's leading group for epidemic response and treatment, said at a press conference on October 13 that there is no scientific understanding of the pathogenic mechanism and final duration of the sequelae of new coronavirus. Unlike general flu and known diseases, scientists still have many unknowns about the new coronavirus.
