COVID-19: Data

Long-Term Trends

The data here show COVID-19 trends in New York City since the city’s first confirmed case was diagnosed on February 29. You can also download our data and technical notes on Github.

Cases, Hospitalizations and Deaths

These charts shows the daily number of confirmed COVID-19 cases by diagnosis date, hospitalizations by admission date and deaths by date of death. Due to delays in reporting, which can take as long as a week, recent data are incomplete.

Virus (Diagnostic) Testing

A virus (diagnostic) test shows if you have COVID-19. Our data on cases, hospitalizations and confirmed deaths reflect people who tested positive.

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.

The charts below shows the daily number of people who were tested since the start of the pandemic in NYC.

Percent Positive Citywide and by Age

The percent of people tested who test positive can show if we are lowering community transmission.

Test Result Lag Time

There is a lag between when a test is taken and when the result is reported to the Health Department. This lag, or turnaround time, can depend on whether a person is tested at a hospital or at an outpatient clinic, the laboratory used and the total volume of testing locally and nationally, among other factors.

Recently, most results have been reported within two days.

Antibody Testing

An antibody test can show if you have ever had the virus, but it does not show if you currently are infected.

It is not yet clear whether testing positive for antibodies provides long-term protection from COVID-19.

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 ending on the listed date.

Emergency Department Visits

These charts show people who visited the emergency department with clinical signs and symptoms consistent with COVID-19 illness (including flu-like illnesses and pneumonia), and those who were then admitted to the hospital, since the start of the pandemic. While some of these people did not test positive, this data can be an early warning sign for community transmission of COVID-19.

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.
