Over the past several weeks, COVID-19 cases have started to surge once again. The new record-breaking numbers and rising deaths have triggered some cities to roll back reopening plans and place new restrictions on restaurants and bars.

New York Governor Andrew Cuomo was the first to roll out new restrictions, including closures for in-person service at restaurants and bars from 10PM to 5AM. Those restrictions went into effect last Friday, and now other states are following. California Governor Gavin Newsom, for example, announced a similar plan to implement a curfew from 10PM to 6AM for restaurants and bars, and it has reduced outdoor dining capacity.

These officials are relying in part on data from the Centers for Disease Control and Prevention that has found a relationship between indoor eating and the spread of the virus. In September, the CDC  published research that found that patients with symptomatic COVID-19 were twice as likely than uninfected controls to have dined in a restaurant, including indoor, patio and outdoor seating.
