As the BA.2 variant spreads, here are the symptoms to watch out for – NBC Chicago

While the omicron variant was the dominant strain of COVID-19 earlier this year, the BA.2 subvariant, also known as the “stealth omicron,” now accounts for the majority of coronavirus cases in the United States.

According to the latest data from the CDC, the estimated number of cases linked to the BA.2 subvariant was 68%, which was actually a decrease from the previous week. Cases of the BA.2.12.1 subvariant, BA.2’s own subvariant, rose 9% in the United States over a one-week period, as shown by CDC estimates.

BA.2.12.1 accounts for 28.7% of COVID cases across the country, data revealed.

Cases of the BA.1.1 variant, the original omicron variant that spread like wildfire over the winter, are now down to 2.8%, according to CDC estimates.

The rise in omicron subvariants coincides with an increase in metrics for Illinois, which has seen an increase in cases and hospitalizations in recent days, according to data from the state Department of Public Health.

With the spread of subvariants continuing to climb, what symptoms should you watch out for?

Northwestern’s Dr. Michael Angarone, an associate professor of medicine in infectious diseases, previously said the explained symptoms of BA.2 are similar to those seen in many COVID infections.

NBC News reported that symptoms associated with BA.2 appear to largely mirror a small number of symptoms commonly reported in omicron infections. These include:

  • Cough
  • Fatigue
  • Congestion
  • Runny nose

At this point, the main difference between the new versions of omicron and the one that has already exploded in the United States is transmissibility.

White House chief medical adviser Dr. Anthony Fauci estimated that BA.2 is 50% more transmissible than the original omicron line.

For some people, the coronavirus causes mild or moderate symptoms that disappear within a few weeks. For others, it may not cause any symptoms. For some, the virus can cause more serious illnesses, including pneumonia and death.

For those who have been vaccinated and boosted, the cold-like symptoms experienced as a result of an omicron infection are mostly the same regardless of the subvariant.

“Omicron symptoms have been pretty consistent. There are fewer people losing their sense of taste and smell. In many ways it’s a bad cold, lots of respiratory symptoms, stuffy nose , cough, body aches and fatigue,” said Dr. Dennis Cunningham, medical director of infection control and prevention at Henry Ford Health in Detroit.

Experts generally agree that the public shouldn’t worry too much about the emergence of each omicron sub-variant.

“At some point, you just can’t get nervous every time there’s a new variant, because there’s always going to be a new variant,” said David Montefiori, a professor at Duke University Medical’s Human Vaccine Institute. Center. “We went through several waves of variants that really mattered a lot, but we could come out of it because there is so much immunity built up in the population.
