Current norovirus notices

Dates are the official event dates from the source, not when we ingested the row. A short list is not complete coverage. 8 notices are country- or national-scale and should not be read as nearby exposures.

How to read this map

Health departments post norovirus when they name that virus — often after a school, restaurant, cruise, care facility, or shellfish investigation. Other vomiting illnesses belong on foodborne or restaurant pages until a source names norovirus.

Reporting lags symptom onset. Winter clusters are common in closed settings; summer reports still occur. CDC NoroSTAT and state letters describe trends, not whether you were exposed.

Places named in current norovirus notices

These links follow city or region names in the notice. Country-only items are omitted so a national centroid is not presented as a local hub.

FAQ

Is every stomach illness norovirus?
No. Vomiting and diarrhea have many causes. OutbreakThreat only lists a notice here when the source or our norovirus tag names norovirus. Other foodborne pathogens stay on their own pages.
Does a pin in the middle of a country mean an exposure near me?
No. Many notices are published at state, country, or multi-state scale. We plot the geography the agency named. A national or country centroid is not a nearby venue or household exposure.
If this page lists no current notices, is there no norovirus activity?
No. Missing reports are not proof of no disease activity. Agencies publish on their own schedules, and we only show notices we have ingested and can link.
Can I get email alerts for norovirus near me?
Yes. A Free account can watch one saved place and receive a weekly digest of matching official notices. Paid plans add more watches. The norovirus map stays free to browse.
