U.S. new crown pneumonia outbreak has severely rebounded, experts warn of more dangerous strainsFly into the homes of ordinary people
The United States is still the country with the worst COVID-19 epidemic in the world, with more than 35.407 million confirmed cases and more than 615,000 deaths. The outbreak in the United States has rebounded rapidly recently, and many numbers have surged. U.S. experts warned that there may be more difficult mutant strains in the United States.
According to data released by the US Centers for Disease Control and Prevention, the number of newly diagnosed cases in the United States last week increased by 43%, and the number of deaths in a single day increased by more than 39%, and the trend of cases is getting younger.
Among hospitalized cases in the United States, people aged 18 to 49 accounted for 41%. The number of pediatric hospitalizations is 3.5 times higher than a month ago. The American Academy of Pediatrics reported that in the last two weeks of July, the number of patients under the age of 17 increased significantly, from 39,000 cases per week to 72,000 cases per week, an increase of 84%.
Most of the new cases in the United States are infections with the delta mutant strain. Authoritative American experts warned that if the United States cannot control the spread of the virus in the community, sooner or later, new mutant strains that can evade vaccine protection and are more difficult to deal with will appear.
