Cases, Hospitalizations and Deaths

These charts shows the daily number of confirmed and probable 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.

Defining Confirmed and Probable Cases and Deaths

Trò chơi xổ số Việt NamCOVID-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

Trò chơi xổ số Việt NamMolecular 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.

Trò chơi xổ số Việt NamAntigen 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.

Molecular and Antigen Testing

These charts show the number of people tested by molecular tests and antigen tests each day since the start of the pandemic in NYC.

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.

Molecular Testing

Trò chơi xổ số Việt NamThese charts show the percent of people tested positive and the testing rate, by age, for molecular testing. All of our data on confirmed cases reflect people who tested positive with molecular testing, which is the most reliable type of COVID-19 test.

Molecular Test Result Turnaround Time

There is a turnaround time between when a person receives a test and when the result is reported to the Health Department. This 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. The below charts show data from molecular tests only.

Antibody Testing

Trò chơi xổ số Việt NamAn 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 DataTrò chơi xổ số Việt Nam: 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 Turnaround Time: Our data are published with a three-day turnaround time, meaning that the most recent data in today's update are from three days before.

This turnaround time 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.
