CHICAGO — Restrictions aimed at limiting the spread of the coronavirus in Chicago’s restaurants and bars will ease slightly this week, letting more customers dine and drink indoors.

Mayor Lori Lightfoot announced the decision Monday as Illinois officials said 1,709 new confirmed cases of the coronavirus have been reported statewide and 13 more people have died.

Since the start of the pandemic, Illinois has reported 289,639 confirmed cases and 8,614 deaths. According to state health data, 79,765 of those cases and 2,956 deaths have involved residents of Chicago, the third-largest city in the U.S.

Statewide, 3.7% of the tests performed during the last seven days have been positive. In Chicago, Lightfoot said that figure is at 4.5%.

The changes to Chicago’s rules will let restaurants increase capacity from 25% to 40% — with a cap at 50 people within one room. Bars without food service, which the city shut down this summer after a brief reopening, can resume indoor service at 25% capacity or a maximum of 50 people.
