Huge crowds gather for Lollapalooza despite rising Covid cases across the US

Lollapalooza music festival, one of America's largest events is underway this weekend, seeing huge crowds gather despite rising Covid-19 cases across the US.

The four-day music festival is expected to draw more than 100,000 people to downtown Chicago each day, at a moment when coronavirus cases are on the rise and vaccinations have plateaued.

Photos and videos of unmasked crowds are spurring fears that the music festival could become a Covid-19 superspreader event.

Lollapalooza has said their policy is for unvaccinated people to wear masks and show a recent negative Covid test.
