A report to the network "CNN" American, Centers for Disease Control and Prevention in United State Last April, I concluded that the majority of Americans had contracted the disease COVID-19 caused by the virus by February 2022.
Officially, 87 million cases of corona have been recorded in the country, but the Centers for Disease Control believes that the numbers are much higher, and some estimates indicate that the number of infected people has reached 187 million.
Some people think that the corona infection is for one time and it is over, but with the passage of time what is known as the long corona appeared, which lasts for months, not two weeks, as is believed.
The new thing here is that infection with corona again after recovering from it has become common.
The Centers for Disease Control and Prevention stated that it is possible for a person to be infected with corona several times even after recovering from infection with the virus.
Ziyad Al-Ali, director of the Missouri Center for Clinical Epidemiology, says: "If you asked me a year and a half ago about the second infection with corona, I would tell you that I might have had a patient here or there, as it was a rare occurrence."But that has now changed.
And there were changes that led to the outbreak of the second infection, including, according to the Centers for Disease Control and Prevention, the emergence of new mutations that increase the possibility of a second infection with the epidemic.
For example, Dr. Chen Hogan in California says that the BA.4 and BA.5 mutants have the ability to evade immunity even in those who have previously been infected with the virus.
For his part, Andrew Robertson, Western Australia’s chief health officer, said: “What we’re seeing now is an increasing number of people who have had the BA2 mutation… and then they were infected four weeks later.”".
