Mayor Bill de Blasio says parts of Brooklyn and Queens are seeing an increase in coronavirus cases.

The Department of Health says the increase is cause for concern and more action will be taken if non-compliance and safety precautions are ignored.

The Department of Health says it has seen a 2% increase in the Williamsburg section of Brooklyn. In Queens, there has been a 2.24% increase in Kew Gardens, and a 3.69% increase in Far Rockaway.

One of their biggest concerns is a section in Brooklyn that they’re now calling the “Ocean Parkway Cluster,” made up of Midwood, Borough Park and Bensonhurst, where there has been a 4.71% increase.

Health officials say the number of cases has tripled and the uptick in cases accounts for 20% of the cases citywide as of Saturday, according to the Department of Health.

The concern they say is that this could spread to other neighborhoods unless action is taken. The mayor stresses that people must wear face coverings when in public if unable to maintain at least six feet of distance.

They are also encouraging people to get tested, but reminding people that if you had the antibody test you should not use those results to determine whether to return to school or work, because past infection does not guarantee protection from being infected again.

The mayor says they are focusing testing and resources into the areas where they are seeing an uptick, while also making robocalls and distributing hand sanitizer and masks.
