Joseph Ortiz walked to the home of a man who was tested COVID-19. The test showed the man has the disease. Ortiz was unsure what to expect during his visit. The person had not answered telephone calls from New York City’s contact tracing program. New York officials set up the program to keep the coronavirus from spreading. The goal was to get new diagnosed people to identify others they might have infected before the virus spreads further. “You never know what you’re going to get,” Ortiz told The Associated Press. He added that “sometimes you have people who are really appreciative; they like that we’re out here trying to end the pandemic.” Such is the work of what appears to be the biggest contact tracing effort in any city in the United States. New York has over 3,000 people making phone calls, going door to door, and asking people about their health. New York Mayor Bill de Blasio has called the effort an “amazing success.” The city says it is now meeting its goal of reaching about 90 percent of all newly diagnosed people and completing interviews with 75 percent.
