Outbreak Summary
Still need an outbreak summary.

Cholo’s is a popular (and generally good) Mexican restaurant up on the North Shore of Oahu, the most populous island in Hawaii.

Unfortunately for them, though, they apparently had some workers who had norovirus infection and proceeded to
contaminate the food they prepared. The outbreak was picked up via participants of a century (bike) ride who ate at the restaurant after their event, got sick, and reported their illness to us.

We subsequently identified at least 80 individuals who had
consumed food at the restaurant from April 8–10, 2011. Stools from about 10 of them were positive for norovirus.

The restaurant engaged in extensive cleaning and education of their workers and was able to continue operations afterward.
