A novel coronavirus pneumonia conference was held in December 28th. Maria Van Kohof, who is the technology director of the health emergency project, said that with the continuation of the epidemic, more new crown virus variants will be found. Although the new coronavirus variants found in South Africa and Britain appeared at the same time, they were different variants.
British researchers found that there were no significant changes in the hospitalization rate, 28 day mortality rate and reinfection of patients infected with mutated new coronavirus, and will continue to study antibody response. South African researchers are also conducting epidemiological studies on the virus variants in South Africa to determine if there is any change in their infectivity. (Sources: Zhu He I CCTV )
