COVID-19: Data

Testing Data

This page provides data about testing for COVID-19, either through a virus (diagnostic) test or an antibody test.

  • A virus (diagnostic) test shows if you have COVID-19. Data on these pages for cases, hospitalizations, and confirmed deaths are for people who tested positive with a virus test.

  • An antibody test can find out if you have ever had the virus.

From March to early May, we discouraged people with mild and moderate symptoms from being tested, so our data from that period represent mostly people with severe illness. More recent data provide a broader picture now that more people without severe illness are getting tested.

Virus (Diagnostic) Tests

These charts show the number of people tested for the virus, the number of people who tested positive and the percent of people tested who had positive results. The charts include data from each day of the outbreak in NYC.

Antibody Tests

These charts show the number of people tested with antibody tests, the number of people who tested positive and the percent of people tested who had positive results for the week starting on the listed date.

     

People can test positive for antibodies after they have initially been exposed to COVID-19, sometimes when they no longer test positive for the virus itself (through a diagnostic test). It is not yet clear whether testing positive for antibodies provides long-term protection from COVID-19.




Antibody Testing by ZIP Code of Residence

These maps show the number of people tested with antibody tests by ZIP code of residence, the testing rate per 100,000 people in that ZIP code and the percent of people tested who had positive results.




Antibody Testing Rates

These charts show antibody testing rates and percent positive by group. Breakdowns by race/ethnicity are not available because most laboratory records do not include the patient’s race/ethnicity.
