Norovirus outbreak hits 125 aboard Ruby Princess on 20-day Alaska cruise
A norovirus outbreak infected 125 people on the Ruby Princess during a 20-day San Francisco–Canada–Alaska cruise (102 passengers and 23 crew). The ship docked in San Francisco and will be cleaned and disinfected before its next voyage. CDC data show several norovirus outbreaks on cruise ships this year; prevention centers on thorough handwashing (at least 20 seconds) since hand sanitizer is less effective against norovirus.
