Where COVID lurks: Restaurants and gyms are behind infection surge and where you're most likely to catch virus, while malls, convenience stores and pharmacies are all low-risk, cell phone tracking data suggests

A computer model analyzed 10 cities and looked at where people go during the day, how long they stay and the occupancy. It found most COVID-19 occur at 'superspreader' sites, such as coffee shops, full-service restaurants and gyms Keeping department stores, convenience stores, gas stations and pharmacies open contributed relatively few additional infections. Next, they created trade off charts to determine how limited occupancy could reduce infection risk. In Chicago, reopening at 100% occupancy would lead to nearly 3.5 million cases but a 20% occupancy cap would only lead to about 500,000 new infections. In Los Angeles, full capacity would lead to more than three million new cases but limiting occupancy reduce the number of infections by 75%
