New York State Flu Tracker - NYAPD

Influenza, often referred to as ‘flu’, is a contagious respiratory illness caused by influenza viruses. Seasonal flu epidemics occur yearly during the colder months. Although the yearly impact of influenza varies, it affects the health of New Yorkers each season. Most people who get sick with flu will have mild illness and will recover in less than two weeks without medical care. Some people, such as older adults, young children, pregnant women, nursing home residents, and people with asthma, lung disease, heart disease, diabetes, or obesity, are more likely to develop flu-related complications. Getting an annual flu shot, staying home while sick, washing your hands often, and other good health habits help prevent the spread of influenza.

This dashboard tracks laboratory-confirmed influenza cases each week across New York, in each region and county, and compares trends between seasons.

Data Source:

New York State Department of Health continues to focus on COVID-19 cases. The reported number of lab-confirmed influenza cases and hospitalizations are steadily declining. With only sporadic cases being reported statewide and overall influenza activity remaining low, the New York State Department of Health discontinued influenza surveillance reporting for the 2019-20 season earlier than planned. Data for the 2020-21 influenza season will resume in mid-October.

The data represents laboratory-confirmed cases of influenza which meet a standardized case definition and are reported to the New York State Department of Health during the influenza season. Weekly and season-to-date data are displayed for the current and the previous three influenza seasons: 2019-20; 2018-19; 2017-18; 2016-17.
