NEW YORK (Reuters) - New York City's Health Department has identified a new cluster of COVID-19 cases in Brooklyn, and said on Tuesday a marked uptick in infections there and in some other neighborhoods is "cause for significant concern."

Four areas have seen a large increase in cases between early August and last week, Patrick Gallahue, a spokesman for the city's Department of Health and Mental Hygiene, wrote in an email to reporters.
