According to Johns Hopkins University COVID-19 tracking, the United States reported 22931 cases of new coronary pneumonia yesterday and 312 deaths.
The CDC stated at a national press conference that the Detla variant virus has now becomeThe most important strain of the new crown in the United States!
According to the latest report from the US CDC, in the past week, the number of confirmed new crowns in the United States has increased again at a rate of 11% every day, and the number of hospitalizations has increased by 7%.among them,The average number of new cases per day is about 1.39, and the number of new hospitalizations is 2,000.
These figures have triggered a new wave of concerns in the health sector.
Delta virus break prevention
It is reported that the Detla virus currently accounts for51%, Among them, the number of patients in the Midwest region of the United States is more, accounting for the number of cases in these regions80%.
The vaccination rate in each state in the United States, the darker the color, the higher the vaccination rate
According to the CDC survey, the vaccination rate in areas with more than 10 cases per 100 people is far below the national level, and in some placesThe vaccination rate is less than 40%.
For example, Mississippi has had a lot of severe childhood diseases recently. However, this week’s adult vaccination rate is rankedSecond to last in the U.S..
Here, the CDC once again appeals to all Americans to get vaccinated as soon as possible.
CDC: Complete vaccination as soon as possible
7 month 14 day,Public health officials in Los Angeles County said that as the number of new coronary pneumonia cases continues to increase rapidly, vaccinated people also need to wear masks indoors again.
It is reported that the mandatory indoor mask wearing order came into effect on July 7. Health officials said: "This is a time when all people need to participate."
Although the mandatory mask order returns, people can still eat indoors, but they can only take off their masks when eating or drinking.
CDC: Complete vaccination as soon as possible
According to CDC, in the past month, the United States99.5% of new crown deathsThe cases are all people who have not been vaccinated.
According to medical model analysis, the US vaccination program has saved approximately 27.9 lives and avoided hospitalization of 125 million.
Although the vaccine is not 100% resistant to the virus, it can protect youNot to be attacked by the Delta variant and cause severe illness or death.
up to now,3.8 million doses of COVID-XNUMX vaccine have been delivered nationwideAfter 3 million doses were injected, 1.5 million Americans were fully vaccinated, and 67.2% of adults received at least one dose.
According to statistics collected by Public Health Scotland and published in the authoritative medical journal Lancet, at least two weeks after the second dose of vaccination,Pfizer vaccineThe protection rate against Alpha mutation is 92%, and the protection rate against Delta drops to 79%.AstraZeneca, OxfordThe protection rate of the vaccine against Alpha dropped from 73% to 60% against Delta.
But even so, the virus is still cunning.
The virus is cunning, and the vaccination is still infected
Just last week, a couple in Houston, Texas, USAoutdoorA wedding was held.The wedding also requires guests to showVaccination record.A total of 92 people attended.
However, I never expected that 4 days later, a pair of male and female guests from India were diagnosed with the Delta mutant strain, which infected the other 4 guests who had been fully vaccinated, the Indian man who became the firstEventually die, And 1 person developed severe illness.
The horror of the Delta mutant strain cannot be ignored.Not only is it more than twice as infectious as the original new coronavirus.and
Can also evade the immune system function in the body, soReduce vaccine protection rate.
However, Fauci, the chief medical adviser of the US government and an infectious disease expert, said that according to the current data in the United States, Americans who have been fully vaccinated against the new crownNo need for booster injection.
But as more data continues to be obtained, the guidelines may change.
For young children and the elderly with underlying diseases, masks are still an effective way to avoid the epidemic.
In addition, I remind everyone to try to avoid large gatherings,Maintain social distancing and pay attention to hand hygiene.
