What this means
Every state requires healthcare providers and labs to report a list of specific diseases (typically 70–100) to the state — including measles, hepatitis A, tuberculosis, salmonella, E. coli O157, Legionnaires', and Lyme disease. State public health investigates clusters and posts outbreak updates when public action is warranted (e.g., a restaurant exposure or a campus measles case). Data rolls up to CDC's National Notifiable Diseases Surveillance System (NNDSS).
What you can do
- If you think you've been exposed to an outbreak, contact your county or state health department — most have a 24-hour nurse line.
- Make sure your routine vaccines are current (MMR, Hep A, Tdap, varicella).
- For foodborne outbreaks: keep receipts and a list of recent meals — public health investigators will need them.
- Report a possible outbreak: call your county or state health department directly.
