Mayor Bill de Blasio visited one of the COVID-19 walk-in sites that's helping expand testing in the Bronx Saturday, as the conversation around the coronavirus outbreak begins to shift toward testing capacity.

The mayor delivered some good news to those who have been on the front lines of the pandemic, as well as some Dunkin' Donuts to thank them for their service.

Mayor de Blasio and Councilmember Vanessa Gibson gave the health care workers a heartfelt thank you at the COVID-19 community testing site run by NYC Health + Hospitals/Gotham Health.

The new walk-in site sees lines of potential coronavirus patients and is one of at least five to recently open across the city in communities hardest hit by the pandemic, according to NYC Health + Hospitals.

The five new sites are able to conduct a total of 2,400 tests per week. Those over 65 with pre-existing conditions take priority.

The mayor, wearing a mask at times when interacting with the health care workers, says the city has seen real improvement the last couple of weeks, attributing it to social distancing and because of that he says grassroots community testing sites are getting more equipment to keep workers safe.

"I just want to say thank you, because what you're doing is just so important, so important, each and every person and I think you know it. You're there for them and you give them that answer, that support,” says Mayor de Blasio.

The mayor also says the city is going to provide hotel rooms to some patients who cannot isolate from their families because of their living situation. He added that the next phase is continuing to ramp up testing and contact tracing.
