(CNN) A small minority of places where people go frequently account for a large majority of coronavirus infections in big cities, according to a new modeling study. The study, published in the journal Nature on Tuesday, suggests that reducing the maximum occupancy in such places -- including restaurants, gyms, cafes and hotels -- can slow the spread of illness substantially. The researchers examined Covid-19 case counts for each area and took a close look at how often people traveled to certain non-residential locations or "points-of-interest." They added that the new study also "deepens our understanding" of possible factors behind disparities in Covid-19 cases by income level. "This type of observation is possible only because of the high level of detail on venue size and occupancy in the data."
