Santa Cruz Sentinel reported that more than 80 people who ate at a Santa Cruz County hotel restaurant reported getting sick in the past week and health officials blame it on something simple: failure to wash hands. The Santa Cruz County Health Services Agency issued an advisory Friday, saying it was investigating how more than 1,000 people were exposed to the gastrointestinal virus during the past seven days.  Public health staff suspect the cause of the outbreak is a “highly contagious virus” that can be passed human to human. Symptoms include vomiting, nausea and diarrhea. “One person carrying it is the typical mode of transmission,” Kennedy said. “It’s fecal-oral contact. It’s not washing hands – especially people who are preparing and handling foods.”
