Why some Americans haven’t got covid yet and why it’s not inevitable

When an omicron wave hits the United States, it spreads like wildfire across the country.

Various models estimate that 50% to 75% of Americans were infected by the variant by the end of the growth.

So, what does this mean for the rest of the U.S. population who did not become infected with COVID-19 during the last wave?

Since Omicron has shown the potential to cause groundbreaking infections despite being vaccinated, there are fears that everyone will be infected with the virus at some point. However, it is important to note that covid vaccines continue to be highly effective for the primary purpose of preventing hospitalization and death.

However, public health experts say that it is not inevitable that Americans have not yet received Covid and that there are several reasons why they have finally been able to avoid infection, including some behaviors such as being serious about masks and social distance, vaccination rates. And even genetics.

Why some people still have not got Kovid

Doctors say millions of Americans still have some reason to be infected with the virus.

One of these factors is human behavior, which means that people take appropriate precautions to reduce their risk of becoming infected.

“Sometimes people don’t get infected because they’re very careful,” Dr. Mark Sidner, an associate professor in the Department of Medicine at Harvard Medical School, told ABC News. “There are some people who have their own health behaviors or are concerned about their own health or the health of their loved ones.”

He continued, “Maybe they have sexually transmitted diseases. They may be the kind of people who are basically under house arrest, or don’t really communicate with others, or are especially careful about things like social distance and masks, and that can stop a lion’s share of infection.” Reduce the risk where you are less likely to be infected. “

These people are also more likely to be vaccinated and vaccinated, and experts say it is impossible to ignore the impact that immunization rates have had on Americans.

Dr. Jonathan Grain said there are social and environmental factors that can determine why some Americans became infected and others did not, including how much time people spend with others and where they interact.

“Some people may have more contact with regular people than others,” Grain, director of epidemiology at Cedars-Sinai Hospital in Los Angeles, told ABC News. “There are probably environmental reasons as well, the virus is probably transmitted more efficiently in certain situations such as the classically weaker-ventilated space than the indoor, outdoor space.”

However, genetics may play a role.

Dr. Stuart Ray, a professor of medicine at Johns Hopkins University, said a similar situation has been observed among people who are at high risk of HIV but have not contracted the disease.

“One of the things that was discovered was people who had mutations [a certain] Receptor 6 and it was associated with not being infected with HIV, and among those who are infected with abnormalities, AIDS progresses very slowly, ”he told ABC News.

Although no clearly identified gene has yet been found, Ray said some people are genetically less susceptible to covid.

Is COVID-19 infection inevitable?

Experts say they do not believe that COVID-19 infection is inevitable or at least inevitable for everyone.

“It’s been two years now and not enough people have been infected yet. It’s good evidence that it’s not inevitable that everyone will get it,” Green said. “One thing we have clearly identified is that vaccination is the most important variable in determining how safe someone can be.

However, Ray said he thinks Americans who are vaccinated but not yet infected will eventually.

“As these forms become more contagious, the likelihood of those people becoming infected seems significant,” he said. “I think people who have not been vaccinated and have not been vaccinated will eventually get it because we are not going to track the infection as closely as in the past and so there will be less awareness because of the virus hire. No. “

Dr. Peter Chin-hong, an infectious disease specialist at the University of California, San Francisco, says the cowardly situation in Hong Kong is a “terrible story” about what could happen in an immunized country.

According to Our World in Data, Hong Kong currently has the highest COVID-19 death rate in the world, with a seven-day rolling average of 37.68 per million people.

“A lot of people were vaccinated in Hong Kong, but it was the opposite in the United States,” he said. “In the United States, many seniors are vaccinated and raised, but in Hong Kong the opposite is true. Very few seniors are vaccinated so that when they get it, even something ‘light’ like Omicron, many people die, so it A warning story. “

There is no number that determines whether the United States has sufficient resistance

At the beginning of the epidemic, Dr. Anthony Fawcett and other public health experts suggested that 75% to 85% of the animals in the United States needed to be vaccinated to gain immunity.

Currently, only 65.3% of all Americans are fully vaccinated.

Then, when UK Prime Minister Boris Johnson announced last month that he would lift the remaining COVID-19 restrictions in England, supporters said there was a reason because official figures show that more than 98% of England’s adult population has identifiable COVID-19. Antibodies to previous infections or vaccines.

But officials say there are no numbers in the United States for which officials can declare “adequate immunity.”

“The game has changed a bit because the virus has been able to infect and develop many people,” Ray said. “Right now the level of infection is so high that levels of antibodies are needed to prevent infection. The level we need to achieve is difficult to maintain in the long run.”
