Zhong Nanshan's latest research and judgment
About 1.1 to 1.2 billion people in the country have been infected with the new crown
On the afternoon of May 15, at the launch ceremony of the post-marketing clinical study of Leretweritwe, Zhong Nanshan, a recipient of the Order of the Republic and academician of the Chinese Academy of Engineering, said that the mainstream new coronavirus strain currently circulating in Guangzhou is XBB1.9.1. According to the current data of the Guangzhou Fever Clinic, 20%-25% of the fever patients tested are new coronavirus infections.
Zhong Nanshan introduced that whether there are symptoms or no symptoms, if the antibodies corresponding to the new coronavirus in the body are increased, it means that the human body has been infected. From this perspective, according to the measurement, about 85% of the country's people have been infected with the new coronavirus, about 1.1 billion to 1.2 billion people.
According to relevant laboratory studies and real-world studies in Singapore and other places, the antibodies produced after the new coronavirus infection can play a role in protecting the human body within 4-6 months; But if it is faced with variant XBB, its protection may be weakened, "from December last year, it actually seems that this time has now arrived." ”
Zhong Nanshan revealed that the next step is to deal with the new crown virus infection,
On the one hand, it is also necessary to develop vaccines that can cover XBB variants, including MRNA vaccines and recombinant protein vaccines, which are mainly aimed at some special groups, such as the elderly who are immunocompromised or have other serious underlying diseases;
On the other hand, once infected with the new crown, timely drug treatment should be given, which can greatly reduce the mortality rate.
There are data released by the disease control department
These people are the most susceptible to infection
According to Jiangsu CDC, at present, the main epidemic strain of the new coronavirus in mainland China and Jiangsu Province is the XBB series variant. However, from the current surveillance data, the XBB variant has no significant change in pathogenicity compared with the early Omicron subclades.
According to the periodic survey in Jiangsu Province, more than 2/3 of the current infected people are people who have not been infected before. Due to previous vaccinations and natural infections, the vast majority of people still have varying degrees of immunity to the new coronavirus.
According to People's Daily Health Client report, on May 15, the reporter called the fever clinics of many third-class hospitals in Beijing, Shanghai and Guangzhou, and many staff members said that they currently need to queue for more than half an hour, and some hospitals have to queue for 3 hours. A staff member of the respiratory department of a tertiary hospital said that the number of new crown infection patients in outpatient clinics has indeed increased recently, with some being infected for the first time and some being second positive, "Proportionally, there are more people infected for the first time." ”
On May 11, the Beijing Municipal Center for Disease Control and Prevention released the weekly report on the epidemic in the 18th week of 2023, and in the 18th week of 2023 (May 1, 2023 to May 7, 2023), a total of 10,508 cases of 16 types of statutory infectious diseases were reported in the city, and the top two reported cases were novel coronavirus infection and influenza.
