NEW: Our updated Latest Data page now includes transmission levels, showing the rate of new cases by neighborhood, by borough and citywide.
This page shows the latest data and key metrics on COVID-19 in New York City. We update data every day in the early afternoon.

Defining Confirmed and Probable Cases and Deaths
COVID-19 cases and deaths are categorized as probable or confirmed.
- Confirmed Case: Positive result from a molecular test, such as a PCR test. Unless specifically labeled as probable cases, data on cases are for confirmed cases only.
- Probable Case: Defined as any of the following:
- Positive antigen test result
- Person has symptoms and was exposed to a confirmed case
- Person died and their cause of death on the death certificate is COVID-19 or similar, but a positive molecular test is not on record
- Confirmed Death: Death following a positive molecular test.
- Probable Death: Cause of death on the death certificate is COVID-19 or similar, but a positive molecular test is not on record.
Types of Tests
Cases are defined differently based on the type of test used to detect COVID-19.
Molecular tests, such as PCR tests, are the most reliable way to test for COVID-19. Someone who tests positive for the virus with a molecular test is classified as a confirmed case. These tests look for genetic material from the virus that causes COVID-19 (SARS-CoV-2). Unless otherwise specified, data on test counts, test rates and percent positivity only reflects molecular testing.
Antigen tests are faster than molecular tests but can be less accurate. These tests look for proteins on the surface of the SARS-CoV-2 virus. Someone who tests positive with an antigen test is classified as a probable case.
Antibody tests check the blood for signs that you have had the virus in the past. An antibody test may not be accurate for someone with active or recent infection. Someone who tests positive with only an antibody test — and not a diagnostic test — is not classified as a probable or confirmed case.
About the Data: All of the data on these pages were collected by the NYC Health Department. Data will be updated daily but are preliminary and subject to change.
Reporting Lag Time: Our data are published with a three-day lag, meaning that the most recent data in todays update are from three days before.
This lag is due to the standard delays (up to several days) in reporting to the Health Department a new test, case, hospitalization or death. Given the delay, our counts of what has happened in the most recent few days are artificially small. We delay publishing these data until more reports have come in and the data are more complete.
Health Inequities in Data: Differences in health outcomes among racial and ethnic groups are due to long-term structural racism, not biological or personal traits.
Structural racism — centuries of racist policies and discriminatory practices across institutions, including government agencies, and society — prevents communities of color from accessing vital resources (such as health care, housing and food) and opportunities (such as employment and education), and negatively affects overall health and well-being. The disproportionate impact of COVID-19 on New Yorkers of color highlights how these inequities negatively influence health outcomes.
