Holland America ship Veendam was hit by a suspected norovirus outbreak with nearly 4% of passengers sickened by the gastrointestinal bug.
Fifty-seven passengers and 10 crew members were struck down with vomiting and diarrhea as the main symptoms, the U.S. Centers for Disease Control said.
The ship arrived back in San Diego Sunday after a week-long cruise where it was met by a CDC Vessel sanitation program environmental health officer.
Once the outbreak was discovered, the CDC said HAL beefed up onboard cleaning and disinfection following set procedures for such incidents, and implemented a staged disembarkation to limit any further infections.
The cruise terminal was also sanitized ahead of the arrival of passengers for the next cruise.
Just a day later another suspected norovirus gastrointestinal outbreak hit the P&O ship Pacific Eden in Australia with about 60 passengers falling ill.
The ship had undergone a full sanitation program just days earlier following an outbreak on the previous sailing.
