CHICAGO (WLS) — Chicago’s top doctor said there’s “no evidence” Lollapalooza was a “super-spreader” event.
Two weeks ago Thursday, Lollapalooza kicked off.
And on Thursday morning, Chicago’s top doctor, Dr. Allison Arwady, gave some answers about cases linked to the big music festival.
It’s been two weeks since Lollapalooza, so it’s right in the timeline to see any infections linked to the festival.
To this point, the city has held its ground, saying it does not regret hosting Lolla, which saw crowds of more than 100,000 people each day of the weekend festival.
Arwady said Chicago health officials did not see anything that “surprised” them in regards to COVID cases linked to the music festival.

She said there was “no evidence” of a “super-spreader” event, as some feared the large event could become. There were about 385,000 attendees, and roughly 88% were vaccinated, Arwady said.
“If we were more than 90% vaccinated as a city, as a country, we would probably be done with COVID,” she said.
There were just over 200 cases connected to Lolla, according to Arwady. There have not been any hospitalizations or deaths linked to the fest.
Only 0.0004% of vaccinated attendees tested positive, and 0.0016% of unvaccinated attendees tested positive, Arwady said.
“If folks are going to large events, please get vaccinated. It helps reduce risk for everybody,” she said.

She said the protocols put in place for Lolla set a model going forward of how Chicago can remain open and stay safe.
The city is also working with public health departments nationwide to track down any cases linked to the festival.
Arwady said it helped that the festival was outdoors, and protocols like required vaccinations or testing are likely to stay for future events.
She also feels confident enough to allow upcoming indoor events in Chicago.
Just days after Lollapalooza, a total of 100,000 more filled the streets of Belmont Avenue and Addison Street for the Northalsted Market Days, and, of course, the Crosstown Classic was on the same weekend.
As of Thursday morning in Chicago, new cases are up by 39% since last week, and COVID-related hospital visits are up by 6%.
Arwady said that while Chicago is seeing “substantial” transmission, about 362 cases per day, it’s nothing like the first or second surge the city saw.
Breakthrough cases continue to be very rare; most cases are among unvaccinated residents.
Most contracting COVID are in their 30s and 40s; there has not been a significant surge among children, Arwady said.
She also said vaccinations have been increasing over the past few weeks. Over half of 12 to 17 year olds in the city are now vaccinated.
There are some more large gatherings planned in Chicago next month, like the Pitchfork music festival, but Arwady said she’s worried about what the fall and winter could bring with the delta variant, which makes up most cases.
