The city is now monitoring 12 zip codes where the coronavirus positivity rate is above the three percent threshold, officials said Friday.

The Department of Health and Mental Hygiene says the area under zip code 11366, which covers parts of Fresh Meadows and Hillcrest, Queens, is back above a 3% test rate, at 3.07%. That's an increase from 2.98% Thursday. The rate was 3.08% on Wednesday.

The area joins 11 other zip codes that were above that threshold on Thursday - 11219 (Borough Park), 11223 (Gravesend/Homecrest), 11230 (Midwood), 11204 (Bensonhurst/Mapleton), 11210 (Flatlands/Midwood), 11691 (Edgemere/Far Rockaway), 11229 (Gerritsen Beach/Homecrest/Sheepshead Bay), 11367 (Kew Gardens Hills/Pomonok), 11415 (Kew Gardens), 11235 (Brighton Beach/Manhattan Beach/Sheepshead Bay) and 11374 (Rego Park).

Seven other zip codes have been deemed as “areas of concern,” meaning their test positivity rate is between 1.9% and 3%.

All of the areas are located in either Brooklyn or Queens.

Speaking on Inside City Hall Friday, Mitchell Katz, the CEO of NYC Health + Hospitals, said that there was always a risk of cases going up as the city continued to reopen.

"It’s not surprising as we opened up the city that there would be more cases," he said. "We’ve also known that in certain zip codes, we’ve had lower willingness to wear masks. I think there’s also clearly super spreaders, people who are able to spread more than others."

The city and state have unveiled new initiatives to try to slow down the positivity rate.

The governor on Thursday unveiled a smartphone app Thursday that can alert users if they have been within six feet of someone who has tested positive for COVID-19. 

The app, available to iPhone and Android users, sends an alert if a person has been in close proximity to someone for at least 10 minutes who has the virus and has also downloaded the app.

The app will work not just in New York, but New Jersey, Pennsylvania, Delaware and eventually Connecticut. 

The mayor on Wednesday said almost 1,000 city employees, including 400 NYPD officers, have been deployed to those areas to do outreach, distribute masks and issue summonses to those who fail to comply, and that 11 mobile testing sites are also being set up in areas of concern.

Katz once again stressed the need for New Yorkers to follow the guidance of health professionals.

“Right now, we know that we have an effective way of containing the virus, and it’s that people need to wear masks and people need to avoid congregating together, especially inside areas," he said.
