According to health experts in the United States and other countries, the new version of the coronavirus, Omicron BA.5, can quickly re-infect even people who already have protection against the virus.
“What we are seeing is an increasing number of people who were infected with BA.2 and then became infected again after four weeks,” said Andrew Robertson, Western Australia’s director of health. “So maybe six to eight weeks, they’re developing a second infection, and it’s almost certainly BA.4 or BA.5.”
The explanation for this is as follows: When attacked, the immune system produces antibodies to fight off the invader and protect the organism, but this protection diminishes over time, and again, when the person is in this period. If it comes into contact with a subvariant, the virus can find an opening.
A recent study by Columbia University in the United States found that the recent subvariants BA.4 and BA.5 were at least four times more resistant to virus protection than previous variants of the Omicron lineage, says Business. are the weather.
David Dowdy, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, however, points out that reinfections with BA.5 and BA.4 are generally less severe than early COVID-19 infections. He explained that as the virus has evolved to have some resistance to antibodies, our immune system is learning to respond to it without making the body worse.
