COVID-19: Data

Trends and Totals

This page shows data on COVID-19 in NYC since the beginning of the pandemic. Below, click a button to view data on trends over time, or cumulative data.

Long-term trends

The data here show how COVID-19 has affected people in New York City since the city’s first confirmed case was diagnosed on February 29, 2020.

Cases, Hospitalizations and Deaths

These charts shows the daily number of confirmed and probable COVID-19 cases, hospitalizations and deaths by date that each occurred. You can also see monthly hospitalization and death rates by ZIP Code.

Due to delays in reporting, which can take as long as a week, recent data are incomplete.

Diagnostic Testing and Turnaround Time

These testing data show the number of people tested by diagnostic tests (molecular tests and antigen tests) each day since the start of the pandemic in NYC. You can also review the turnaround time from when a person receives a molecular test (such as a PCR test) and when the result is reported to the Health Department.

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 within 60 days of 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.

Diagnostic Tests

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.

Other Tests

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.

Notes on Data by Group

  • Due to the small number of cases among transgender and gender-nonconforming people, data on those cases are not included in this table at this time.

  • Hospitalization rate by borough is impacted by missing data from a number of facilities. This may artificially lower the rate of hospitalization for some boroughs.

  • Data on people identified as other categories, including Native American/Alaska Native or multi-racial, are not provided here. The Hispanic/Latino category includes people of any race. Race and ethnicity information is most complete for people who are hospitalized or have died. There are much less demographic data currently available for non-hospitalized cases.

  • Neighborhood poverty is the percent of a ZIP code's population living below the Federal Poverty Level, per the 2014-2018 American Community Survey. Low poverty: under 10%; Medium poverty: 10% to 19.9%; High poverty: 20% to 29.9%; Very high poverty: 30% and over.

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: Our data are published with a three-day lag, meaning that the most recent data in today's 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.
