Following those conversations, they talked to 81% of the patients’ contacts – or 2,299 people, who may have been exposed.

Tracers were able to identify 331 active cases and help 1,057 people who needed access to medicine, food and other services. They also helped 40 people find hotel rooms to quarantine.

“One of the key reasons why our program has been so successful so early on, is that more than half of all of our tracers – all of our 3,000 working tracers – are people from our hardest hit communities across New York City, making this a local effort with New Yorkers in our communities serving our communities,” he said.
