County public health officials were called out to the cruise ship docked off Santa Barbara Harbor last weekend to check on its health protocols after a number of passengers were reported sick from what appears to be norovirus. Better known as the stomach flu, norovirus causes gastrointestinal issues and often wreaks havoc on cruise-ship passengers because of close living quarters. Public health officials consulted with the onboard physician to make sure there was a “healthy environment” and “good protocol,” said a public health spokesperson.
