Recently, some netizens said on the social platform that they were infected with COVID-19 again. At the same time, the proportion of COVID-19 variant EG. 5 in the global epidemic strains has increased rapidly. Is there any change in the pathogenicity of EG.5 and will it become widespread? What is the current situation of fever clinics in various regions? How to prepare for the autumn and winter epidemic in advance? Xinhua Perspective reporters visited hospitals and interviewed relevant experts in various regions. Drawing: The proportion of Hu Ge EG.5 mutant strains rose to 70%, and there was no obvious change in pathogenicity. "I started to have a fever a week ago, and the antigen result was negative that day, and it was positive four days later." Mr. Huang, who lives in Chaoyang, Beijing, said that he was worried about being infected with COVID-19 mutant strain EG.5 after having a fever. According to the latest monitoring data in China, the proportion of EG.5 variant strains among the epidemic strains of COVID-19 is on the rise, from 0.6% in April to 71.6% at present, which has formed a dominant epidemic in most provinces in China, and is likely to continue this trend in the future. In this regard, the National Bureau for Disease Control and Prevention said that there was no significant difference in the clinical classification between EG.5 infected persons and other XBB sub branch infected persons. The recent national COVID-19 epidemic was generally at a low level and in a wave epidemic situation, which brought less pressure to the medical systems around the country. The mutant strain EG. 5 is a subfamily of COVID-19 Omikron XBB. 1.9.2. On August 9 local time, the World Health Organization announced that it would upgrade the COVID-19 mutant strain EG.5 from a "mutant that needs monitoring" to a "mutant that needs attention". At the same time, it pointed out that at present, the risk posed by EG.5 to public health is low, and there is no evidence that it will cause more serious diseases than other currently prevalent variants. "The daily average number of confirmed cases of COVID-19 infection in the fever clinic of our hospital in August has increased compared with that in June and July." Li Dong, chief physician of the General Infection Department of Beijing You'an Hospital, said that no specific virus strains will be detected during the diagnosis and treatment, but the clinical manifestations seen so far have not changed compared with the previous ones, and according to the patient's own statement, most of them are "two positive" now, and a few are infected for the first time, The 'Three Yang' is almost impossible to encounter. Most cases are mild, with relatively few severe cases. Experts predict that there will be no large-scale epidemic in the short term, and some public are concerned about whether EG.5 will trigger a new round of widespread epidemic. In response, the National Bureau for Disease Control and Prevention stated that China experienced the outbreak of the Omicron XBB series variant strains from April to June this year. The established population immunity still has an immune protective effect on the EG.5 variant strain, which belongs to the Omicron XBB subfamily, and there will be no large-scale epidemic in the short term. Due to the protective effect of the population's immune system, the infection symptoms caused by the mutant strain EG.5 are relatively less severe, "said Hu Yang, deputy chief physician of the Respiratory and Critical Care Medicine Department at Shanghai Pulmonary Hospital. The symptoms mainly include headache, fever, and fatigue. After infection, symptomatic treatment and oral antiviral drugs mostly improve quickly. Shi Bin, director of the emergency department of Shanghai Yangpu District Central Hospital, said that the number of COVID-19 infection cases received this week had actually declined, about half as compared with late July to early August. emergency
