Quick-Spreading Delta Variant Causes Concern, But Chicagoans Can Stay Protected By Getting Vaccinated, Top Doc Urges

"We are going to continue to see new variants," but people shouldn't be overly concerned as long as they take safety steps, the city's top doctor said.

CHICAGO — Concerns about coronavirus’ Delta variant have continued, though local officials have said people’s best bet for protection it still as simple as getting vaccinated.

The Delta variant, which some research has shown could be twice as contagious as the original version of COVID-19, has wreaked havoc across the world. Many places that are less vaccinated have seen cases, hospitalizations and deaths climb as the variant has spread. Notably, the global death toll from coronavirus surpassed 4 million people as of Thursday, though officials estimate many more have died but haven’t been counted.

The Illinois Department of Public Health has found 208 cases of the Delta variant throughout the state, including cases in Chicago.

But Chicago has not seen a major uptick in hospitalizations or deaths from COVID-19 since reopening June 11, despite the variant’s spread. Officials have attributed that to vaccinations: About half of all residents have gotten fully vaccinated, including 60.7 percent of all adults.

Chicago’s deaths, new cases and its positivity rate remain close to its all-time lows from throughout the pandemic. The city’s numbers have crept only slightly up since reopening, with Chicago’s average number of new cases per day about flat compared to a week ago.

And less-vaccinated parts of Illinois — particularly downstate regions bordering Missouri, which has been overwhelmed by Delta — have seen significant spikes in COVID-19.

Overall, the state’s seven-day positivity rate has risen from 1 percent on June 11, when Illinois reopened, to 1.4 percent as of Thursday.

Dr. Allison Arwady, head of the Chicago Department of Public Health, has said the best way to be protected against Delta and other variants is through getting fully vaccinated. People are considered fully vaccinated two weeks after getting the second shot of a two-dose vaccine or after the only shot of a one-dose vaccine.

Arwady, speaking during a Thursday livestream, said the vaccines being used in the United States have been shown to be protective against serious illness and death from known variants like Delta.

Despite that, vaccinations have slowed down in the city, with an average of fewer than 5,000 now being done per day. Arwady has said she’s concerned less-vaccinated communities in Chicago will be hit hard by COVID-19 in the fall and winter.

About 98 percent of Chicago’s most recent COVID-19 cases and deaths have been in people who aren’t fully vaccinated.

And the doctor reminded people it’s normal for viruses to mutate and for variants to emerge — so people shouldn’t be overly alarmed by mutations like Delta or the newly recognized Lambda variant, so long as they take precautions like getting vaccinated or following safety guidelines like masking and distancing among unvaccinated people.

“We are going to continue to see new variants,” Arwady said. “The main question is does one emerge that the vaccines are not highly protective against? Especially against the severe outcomes — that would be the biggest worry.”

Vaccines are free, do not require insurance and are available to everyone 12 and older in Illinois.
