Short answer
Norovirus is not usually described like a respiratory airborne virus, but vomiting can spread tiny contaminated particles nearby.
What it means
CDC focuses on contaminated food, water, surfaces, and close contact. Vomiting events can contaminate nearby surfaces and create short-range exposure concerns in the immediate area.
What to know
The main prevention steps are still handwashing, avoiding close contact while sick, and cleaning contaminated areas carefully.
When to check official guidance
Use CDC guidance for cleanup after vomiting or diarrhea, especially in shared settings.
