Scientists are closely monitoring the PA2 strain of the Omigron variant, which is quietly spreading across the United States.
BA.2 is now diagnosed in more than 30 states, producing about 3.9 percent of new infections and doubling rapidly. Data monitoring of disease control and prevention centers.
“If it doubles to 8 percent again, it means we’re in a period of rapid growth, and we may be staring at another wave of Govt-19 coming to the United States.” Samuel ScorpinoSaid the Rockefeller Foundation’s Director of Pathology Surveillance NPR.
“Of course that’s what we care so much about. We’re all on the edge of our seats,” Mr Scorpino said.
BA.2 is believed to be more contagious than the previous Omigran strain, and has been blamed for a new uprising in Denmark.
However fears about another omigran wave in the United States can be avoided if immunization and immunization rates from previous infections are given.
Said Nathan Groobach, associate professor of epidemiology at the Yale School of Public Health. NPR This will lead to a longer tail than a new rise.
“Many of us think we’re leaving in the United States as quickly as we did in Europe and becoming a new dominant variant,” Mr Krubach said.
Other scientists warn that removing the mask orders will allow the new strain to spread.
The new strain seems to be better at avoiding the protection of the immune system than the original Omigran variant.
BA.2 is considered a “pirated” version of Omicron because of the specific genetic characteristics that make it somewhat difficult to diagnose.
Danish scientists said this week that initial reports suggest it may be 1.5 times more contagious than the original variant.
According to CDC’s Govt Tracker, the United States still records about 100,000 new cases and 2,000 deaths a day from the Omigron uprising.
