New data published by the Centers for Disease Control and Prevention shows that coronavirus RNA, the genetic material of the virus that causes COVID-19, survived on surfaces on the Diamond Princess cruise ship for 17 days after passengers were evacuated.
The study, released Monday, examined the Diamond Princess cruise ship docked in Yokohama, Japan and the Grand Princess cruise ship docked at the Port of Oakland in California, both of which were quarantined due to cases of COVID-19 onboard.
The RNA was found on multiple surfaces in the Diamond Princess cabins up to 17 days after the ship was vacated but before the disinfection process occurred, researchers said.
However, the CDC said that researchers could not determine if transmission occurred from contaminated surfaces on the ship.
The study also deduced that transmission on the Diamond Princess ship largely occurred among passengers before they were quarantined, while crew members were largely infected during and after quarantine.
Since touching objects and surfaces can leave the infectious virus on your fingertips, the CDC recommends washing one’s hands with soap and water for at least 20 seconds. As a backup, a hand sanitizer can be used, best with at least 60 percent alcohol content.
The CDC also recommends people to avoid touching their eyes, noses and mouths with unwashed hands.
