Mobile testing centers have become a key part of the city’s response to COVID-19, helping to keep infection rates low.

At the Clason Point Library, a mobile testing van has been giving coronavirus tests all week for free, even for those without insurance.

Anyone can visit one of the city’s 10 mobile testing vans with two locations in each borough. In the Bronx this week, there’s one in Soundview and one at the McLaughlin Community Center on the Grand Concourse. Those getting tested will get a nasal or oral swab, and their results are in about 15 minutes. Contact tracers will also be on hand if you do test positive and will help you with the next steps to take.

Officials from the city’s Test and Trace Corps say the hyperlocal mobile testing program is one of the ways they were able to get the Sunset Park outbreak under control. The mayor says that they’re a crucial addition to the city’s hundreds of regular testing centers.

“To really go into a neighborhood either we see an uptick in disease or low testing rates or both and address that rapidly and turn it around by really flooding the neighborhood with free testing and outreach in multiple languages and getting people the support they need. It works, it works,” says Mayor Bill de Blasio.

The mobile testing sites will be open from 10 a.m. to 4 p.m. Thursday and Friday. A new list of locations will be released for next week.
