How bad is the EPIDEMIC in the US?
US President Joe Biden posted a video message on his social media account Monday after testing positive for COVID-19, Fox News reported.
In the video, Biden said he was feeling fine and his symptoms were mild. He said he had received two doses of vaccine, two booster shots and his symptoms were mild.
According to US media reports, biden's wife, Jill Biden, has tested negative for coronavirus.
Novel Coronavirus infections have occurred this year in several senior us officials, including Vice President Harry Harris, Speaker of the House Of Representatives Nancy Pelosi and Secretary of State Blinken. Fauci, the White House's chief medical adviser, also tested positive for COVID-19 a month ago.
More than 1.02 million deaths have been reported in the United States
The number of confirmed cases in the United States has exceeded 90 million, according to the latest COVID-19 statistics released by Johns Hopkins University on Monday.
The cumulative number of confirmed cases in the United States reached 900,899,982 and the death toll reached 1,025,898 as of 14:20 P.M. Edt (2:20 p.m. Beijing Time). The United States has the highest cumulative number of confirmed cases and deaths in the world.
About 85% of Americans live in high-risk areas
On July 17, ABC News reported that the CENTERS for Disease Control and Prevention (CDC) currently lists 2,421 counties in the United States as high-risk areas for the outbreak, with about 85 percent of Americans living in those areas.
The recent acceleration of transmission in the United States of new subtypes of the Omicron strain, ba.4 and BA.5, has led to a rebound in the outbreak. As of July 16, the BA.5 subtype has accounted for 75.8 to 79.9% of new infections, according to the CDC.
What is the origin of the omicron BA.4 and BA.5 strains that are causing the global outbreak?
As the Novel Coronavirus omicron subtype variants, the BA.4 and BA.5 strains share a common origin with the earlier Omicron strains, but are more easily transmitted and evade immunity.
According to Nature, the BA.4 and Ba.5 strains are more similar to the previous BA.2 strain, but each carries its own unique mutations, including changes in the virus's spike proteins called L452R and F486V. Moreover, these mutations may alter its ability to lock onto host cells and avoid certain immune responses.
Since 2022, many countries around the world have lifted epidemic restrictions and corresponding prevention and control measures, which also facilitated the rapid spread of omicron BA.4 and BA.5 strains. Some countries have had to face a serious situation: the number of infections has multiplied, health systems have been challenged, patients who have recovered from COVID-19 have been re-infected...
Fauci, director of the National Institute of Allergy and Infectious Diseases, urged Americans not to let their guard down. He believes the number of infections in the United States is significantly underestimated because many people do not report infection after being tested at home. In particular, he warned of a possible surge of cases in the United States between the fall and winter of 2022.
