NEW YORK, NEW YORK - SEPTEMBER 01: A mask-required sign is seen on a door of a store in the Flatbush neighborhood of Brooklyn borough in New York City. A spike in late summer coronavirus (COVID-19) positive cases in the U.S. has some schools, hospitals, and businesses encouraging and at times requiring people to start masking up again.
