These Chicago-Area Counties Are Seeing ‘Substantial' COVID Transmission and Should Mask Indoors, CDC Says

Multiple counties in the Chicago area and across Illinois are seeing "substantial" or "high" community transmission of COVID-19, placing them in the categories in which fully vaccinated people should resume wearing a mask indoors, federal health officials say.

The Centers for Disease Control and Prevention updated its guidance Tuesday to recommend that fully vaccinated people should wear masks in indoor settings again in areas of the U.S. that are seeing substantial or high transmission of COVID-19.

The new guidance marked a reversal from earlier recommendations that said fully vaccinated people could remove masks in most settings.

According to the CDC's COVID-19 data tracker, a map showing levels of community transmission for each county in the U.S., at least eight counties in the Chicago area are seeing "substantial" community transmission as of Thursday.

Those counties include: Will, DuPage, McHenry, Boone, Winnebago, DeKalb, LaSalle and Grundy.

Many of the Illinois' southern and central counties also fall into either substantial, labeled in orange, or high transmission, labeled in red. Some central and northern counties are seeing moderate transmission, labeled in yellow, while just two are colored blue for low transmission.

How to Find Out if You're in an Area Where the CDC Recommends Masks Indoors

In which areas is the CDC recommending people wear masks indoors? The agency points to its COVID-19 data tracker showing levels of community transmission, along with other data, for each county in the U.S.

You can find that map here.

The agency uses a two measures to group U.S. counties into four levels of community transmission: the number of new cases per 100,000 residents and the percent of COVID-19 tests that are positive over the past week.

If a county has reported 50 to 100 cases per 100,000 residents over a seven-day period or has a positivity rate of 8% to 10%, it falls into the "substantial transmission" tier, while those reporting 100 cases or more per 100,000 or have a positivity rate of at least 10% are labeled as "high transmission." Those are the two groups for which the CDC recommends mask-wearing.

169 Dead, 644 Hospitalized in Illinois Breakthrough COVID Cases

More than 160 people have died and nearly 650 have been hospitalized in Illinois due to COVID-19 in "breakthrough" cases after they were fully vaccinated, according to state health officials.

According to data updated Wednesday by the Illinois Department of Public Health, 169 people in Illinois have died due to COVID-19 or complications after being fully vaccinated. That figure equates to 2.44% of COVID-19 deaths in the state since Jan. 1, officials said.

At least 644 fully vaccinated people have been hospitalized in Illinois, IDPH said. The state only reports breakthrough infections among those who have been hospitalized or died, following guidance from the Centers for Disease Control and Prevention, IDPH said.

Those totals mean 10 more fully vaccinated individuals have died and 51 more have been hospitalized in the past week since the state last updated its reported numbers.

The state does not publicize the number of residents who tested positive after being fully vaccinated but did not die or require hospitalization in order to "help maximize the quality of the data collected on cases of greatest clinical and public health importance," IDPH's website reads.

Masks Required Again at Illinois Driver Services Facilities Starting Next Week

Masks will once again be required at Illinois driver services facilities and Secretary of State offices, as well as the State Capitol building, beginning next week, Secretary of State Jesse White announced.

Beginning Monday, Aug. 2, all employees and customers must wear masks inside these buildings.

Cook County Adjusts Masking Guidance for Schools in Wake of New CDC Recommendation

Health officials in suburban Cook County have changed their guidance on masking in schools following new recommendations from the Centers for Disease Control and Prevention this week, which stated that fully vaccinated people should begin wearing masks indoors again in places with high transmission.

"As COVID-19 case counts continue to surge, based largely on the highly contagious Delta variant, the Cook County Department of Public Health (CCDPH) along with the Illinois Department of Public Health, strongly endorses the new CDC guidance calling for universal masking in all schools, K-12 and is revising its School Masking Guidance," the Cook County Health Department said in a statement.

The county noted the "expectation is that schools will follow the CDC masking guidance."

Illinois ‘Fully Aligns' With CDC's Updated Indoor Masking Guidance

The Illinois Department of Public Health is "fully adopting" the Centers for Disease Control and Prevention's updated masking guidance, the state's health department said Tuesday, recommending that fully vaccinated people begin wearing masks indoors again in places with substantial and high transmission.

IDPH also will follow the CDC's new recommendations for masking indoors at K-12 schools, recommending it be done universally among teachers, staff, students and visitors to schools, regardless of vaccination status. 

"While data continues to show the effectiveness of the three COVID-19 vaccines currently authorized in the U.S., including against the Delta variant, we are still seeing the virus rapidly spread among the unvaccinated," said IDPH Director Dr. Ngozi Ezike in a statement, noting that COVID cases and hospitalizations continue to increase, especially among those who are unvaccinated against the virus.

Chicago Travel Advisory: 9 States Added to List as COVID Cases Continue to Rise

Chicago updated its travel advisory Tuesday, adding nine additional states to the list recommending that anyone entering the city from those areas test negative for COVID-19 or quarantine upon arrival.

The city added nine states - for a total of 14 states and one territory - back to the advisory, which is updated each week.

Alabama, Alaska, Arizona, Kansas, Mississippi, Oklahoma, Tennessee, Texas, and Wyoming were all added Tuesday, the Chicago Department of Public Health said.

They join Florida, Louisiana and Nevada, as well as the U.S. Virgin Islands, which were added last week, plus Missouri and Arkansas which were added two weeks prior and all remain on the list.

Recent increases in COVID metrics pushed those newly added states over the threshold of 15 cases per day per 100,000 people to get onto the "orange" list. Any below that mark are on the "yellow" list, with public health officials still warning against non-essential travel.

Chicago's Mask Mandate Could Return as COVID Cases Rise, Lightfoot Says

Chicago could reinstate its mask requirement and other additional COVID-19 safety precautions if the city continues to see a rise in case numbers, Mayor Lori Lightfoot has revealed.

In a conversation with the New York Times published Monday, Lightfoot said, "We're not there yet" when it comes to making such a move, but noted Chicago has reported an uptick in daily case numbers and a slight increase in hospitalizations.

"...We are working very hard to make sure that our daily case rate is below 200," the mayor explained. "If we start to see consistently going over that, we're not only going to look at a mask mandate, we're going to look at other tools we've been compelled to use."

At an unrelated event later Monday, Lightfoot expanded on that when asked about a mask mandate potentially returning.

"We are not in a danger area based upon the metrics that we follow," she said. "But I do think it's smart for people to wear masks. When you're in a group, you don't know who's vaccinated or not."

"We know that the risk to the unvaccinated is extremely high, not only for them getting sick, but also transmitting. So I think everybody's got to make their decisions about what makes the most sense for them," Lightfoot continued. "But if we see a surge anything like we've seen in the past couple cycles, then everything's on the table, but right now, I feel confident with the measures that are in place. But everything is subject to change."

Chicago Doctor Fears Lollapalooza-Related COVID Spike, but Lightfoot Dismisses Criticisms

A prominent Chicago infectious diseases expert is warning that "lots of people" will contract COVID-19 at Lollapalooza this weekend - but Mayor Lori Lightfoot dismissed that warning as coming from "critics on the sidelines."

Dr. Emily Landon, executive medical director for infection prevention and control at the University of Chicago Medical Center, says that the event is a “spreader” event, and that she fears individuals who become infected with COVID, vaccinated or not, could start “wildfires of infection” across the United States.

“I think a lot of people are going to get COVID at Lollapalooza,” she said. “The real problem is not so much that a bunch of young people who come into Chicago getting COVID at this event. The real problem is them taking it back to places that have very low vaccination rates"

 “Lolla has let us down with respect to how vigorously they’re restricting people based on the things that they sort of initially told us (about how) ‘we’re going to be really strict’ and now it’s like they’ve lightened up quite considerably on checking vaccines and negative tests,” she said.

Lightfoot disagreed with Landon’s assessment of the situation, calling the physician a “critic standing on the sideline” and saying that she trusts the medical team put together by the city and festival organizers.

“God bless the critics standing on the sidelines, but I feel confident that the Lolla folks have a good, solid plan in place, and we’re obviously going to hold them accountable to make sure that the plan is enforced,” she said.

Landon, who has appeared at events with Lightfoot during the COVID pandemic, says that she hasn’t spoken to city or state officials in “weeks,” and says that small changes to Lollapalooza could have made it safer, even amid the COVID pandemic.

Lollapalooza Expands COVID Testing Window Even as Cases Climb

As questions linger about whether Lollapalooza should return this summer following a rise in COVID-19 cases, the music festival - Chicago's largest - has extended the window in which concert-goes can undergo a COVID test.

As announced earlier this year, event organizers said a full COVID-19 vaccination or negative test results within 24 hours before attending the festival would be required for admission. But according to the Lollapalooza website, as of Monday, event attendees had to receive a negative COVID-19 test result within 72 hours of attending the event, not 24. However, it's unclear when exactly the testing window expanded.

Voicing concerns about the event taking place amid a surge in cases, Dr. Emily Landon, widely regarded as one of Chicago's top coronavirus experts, said the 72-hour parameter is too lenient, and that the city is risking a massive spike in cases by allowing the event to move forward as planned.

Chicago Dr. Emily Landon Calls for Added COVID Precautions at Lollapalooza

Revealing city and state officials haven't asked for her advice in recent weeks, Dr. Emily Landon, widely regarded as one of Chicago's top coronavirus experts, bluntly stated Lollapalooza - the city's largest music festival - should likely be canceled, citing a rise in COVID-19 cases fueled by the Delta variant.

In an interview Monday, Landon, the executive medical director of infection prevention and control at the University of Chicago Medicine, acknowledged canceling the event, set to take place this weekend, is unlikely.

"And remember how much people are motivated by money," she said. "It really is all about money. People in many cases will throw you, your health, your family's health, grandmother's health under the bus in order to make a few more dollars."

Chicago Doctor Offers Advice for Lollapalooza Attendees Amid COVID Concerns

Lollapalooza is set to take place this weekend in Chicago, and even with the precautions put in place by concert organizers and city health officials, a prominent disease specialist has a very simple message for those attending: Assume that you have been exposed to coronavirus.

With recent increases in cases, mostly driven by the more-contagious delta variant, Dr. Emily Landon, executive medical director for infection prevention and control at the University of Chicago, says that festival-goers must assume that they have come into contact with someone infected with coronavirus, whether or not they themselves are vaccinated.

She said there are steps attendees should take in the days after Lollapalooza to keep themselves and their loved ones safe.

Here's How the Delta Variant Symptoms Differ From the Initial COVID Strain

About 83 percent of new COVID-19 cases in the U.S. have been fueled by the delta variant, and as the surge continues, the number of associated cases is expected to rise even higher in the coming weeks, according to health officials.

Approximately one month ago, on June 19, the delta variant accounted for just over 30 percent of new cases. On July 3, it crossed the 50 percent threshold to become the dominant variant in the U.S. Public health experts nationwide have focused their efforts on encouraging vaccinations as most of those who've contracted the variant haven't been vaccinated.

Studies have shown that the COVID-19 vaccines are effective against multiple variants, including the delta variant. However, when it comes to symptoms, there appear to be key differences.

Coronavirus in Illinois: 7,983 New COVID Cases, 47 Deaths, 139K Vaccinations in the Past Week

Illinois health officials on Friday reported 7,983 new COVID-19 cases in the past week, along with 47 additional deaths and more than 139,000 new vaccine doses administered.

In all, 1,407,929 cases of coronavirus have been reported in the state since the pandemic began. The additional deaths reported this week bring the state to 23,401 confirmed COVID fatalities.

The state has administered 241,150 tests since last Friday, officials said, bringing the total to more than 26 million tests conducted during the pandemic.

The state’s seven-day positivity rate on all tests rose to 3.3% from 1.9% the week before and 1.5% two weeks prior - meaning the positivity rate has more than doubled in the past two weeks. The rolling average seven-day positivity rate on individuals tested rose to 3.5%, up from 1.7% then 2.3% in the past two weeks, officials said.

Over the past seven days, a total of 139,495 doses of the coronavirus vaccine have been administered to Illinois residents. That brings the state’s average to 19,928 daily vaccination doses over the last week, down from the figures reported last Friday, per IDPH data.

State officials say Illinois this week crossed the threshold of 13 million vaccine doses administered since vaccinations began in December. More than 58% of adult residents in the state are fully vaccinated against COVID-19, with 73% receiving at least one dose.

As of midnight, 670 patients are currently hospitalized due to COVID in the state. Of those patients, 135 are in intensive care units, and 44 are on ventilators. All three metrics are a reported increase since last Friday.
