More ways to protect yourself and others
Stay up to date with immunizations recommended for you
  • For most people that means getting a current flu vaccine and a current COVID-19 vaccine. Find a vaccine at vaccines.gov.
  • CDC recommends that all infants receive protection from one of these tools to protect them from getting very sick with RSV.
  • Adults 60 years and older should talk to their healthcare provider about whether a single dose of RSV vaccine is right for them.
Practice good hygiene by covering your coughs and sneezes, washing or sanitizing your hands often, and cleaning frequently touched surfaces
Take steps for cleaner air, for example by bringing in as much fresh air as possible, purifying indoor air, or gathering outdoors
If you get sick, stay home and away from others to prevent spread
Seek health care for possible treatment if you get sick and have risk factors for severe illness
Other tools you can use are masks and distancing

Classifications based on data representing the week ending 11/25/23 (Activity Levels, Illness Trends), using data as of 11/29/23 (Illness Trends) and 11/30/23 (Activity Levels).

Overall levels of respiratory illness are determined weekly based on the percentage of visits to emergency departments and primary care clinics for fever and cough or sore throat reported to ILINet; therefore, a variety of respiratory pathogens that cause similar symptoms may be included. Colors used for levels of respiratory illness were selected to represent the overarching ILINet categories and may not match colors displayed elsewhere.

For illness trends based on visits to emergency departments, trajectory classifications (increasing, stable, or decreasing) are based on a 3-week moving average to smooth week-to-week fluctuations. For example, a jurisdiction could see an increase in the most recent week, but still be classified as “stable” based on trends over the past three weeks. Learn more about respiratory illness data.

As of May 10, 2024, COVID-19 hospitalization level data are no longer included on this page, as, effective May 1, 2024, hospitals are no longer required to report COVID-19 hospital admissions data to HHS through CDC's National Healthcare Safety Network (NHSN). Data voluntarily reported to NHSN after May 1, 2024 will be available starting May 10, 2024 on COVID Data Tracker Hospitalizations and data.cdc.gov.
