CHICAGO — State officials are keeping a close eye on COVID-19’s BA.2 sub-variant as it spreads in Illinois, Gov. JB Pritzker said Monday.

BA.2 is an even more contagious sub-variant of Omicorn, the version of COVID-19 that sent cases to record highs in Illinois in late December and early January. The sub-variant was detected here in Illinois, and it’s estimated it accounts for about 25 percent of current COVID-19 cases in Illinois, Pritzker said at an unrelated news conference.

Despite BA.2 making up a rising percentage of cases in Illinois, there has not been a proportional uptick in reported cases and hospitalizations, Pritzker said.

“Illinois is currently in a good place,” Pritzker said. “That said, [the state health department] is watching the trend of this sub-variant very closely. The virus is very much still here and with us, and it isn’t going away.”

The state’s replenished its stockpile of medical supplies, and it has more than 1.5 million rapid tests and another half-million arriving in the coming weeks, Pritzker said.

The governor also called on schools to look at how much COVID-19 testing they can do and to prepare to do more if there’s another surge.

“If conditions here change, I’ll address the people of Illinois with needed action,” Pritzker said.

Chicago’s officials have also said they’re keeping an eye on BA.2’s spread in the city, though they’re not yet alarmed.

The sub-variant has spread rapidly in Europe, driving up cases to near-record or even record levels in several countries, according to The New York Times.

Chicago health Commissioner Dr. Arwady said this week her agency is watching Europe for an idea of what could happen here. Europe is not doing well, she said during a Tuesday livestream, and she’s concerned about what’s happening there.

BA.2 has been found in Chicago, and it has made up and increasing number of COVID-19 cases in the city as the weeks have passed. But the initial Omicron variant remains the dominant version of COVID-19 being found in Chicagoans.

For now, people should just be cautious, not necessarily alarmed, experts told The Times. They advised people to get vaccinated and get a booster shot to ensure they’ll be protected if BA.2 does fuel another wave of COVID-19 in the United States.
