The Chinese Coronavirus survived for up to 17 days aboard the Diamond Princess cruise ship according to this study published yesterday by the Centers for Disease Control and Prevention.
The study examined the Japanese and U.S. government efforts to contain the COVID-19 outbreaks on the Carnival-owned Diamond Princess ship in Japan and the Grand Princess ship in California. Passengers and crew on both ships were quarantined on board after previous guests, who didn’t have any symptoms while aboard each of the ships, tested positive for COVID-19 after landing ashore.
The virus “was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess but before disinfection procedures had been conducted.”
“COVID-19 on cruise ships poses a risk for rapid spread of disease, causing outbreaks in a vulnerable population, and aggressive efforts are required to contain spread.”
