A new study has found that coronavirus was able to survive inside cruise ship cabins for more than two weeks after they were vacated, including the cabins of people who tested positive but had no symptoms.
Traces of new coronavirus were found on surfaces in cruise-ship cabins for as many as 17 days after passengers left, researchers said, though it wasn’t possible to determine whether they caused any infections.
Researchers looked at the rooms of infected passengers aboard the Diamond Princess, both those who showed symptoms and those who didn’t, according to a study Monday in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report.
The ship, operated by Carnival Corp.’s Princess Cruises, had more than 700 coronavirus cases. It was quarantined for a time off of Yokohama, Japan, and was the largest outbreak outside of mainland China at one point.
The study results were published on the CDCs website here. One fact that needs to be pointed out is that the virus survived for this long in cabins “before disinfection procedures had been conducted.” So no one is suggesting this thing lives on for days despite a good scrubbing, only that it can linger a surprisingly long time when no cleaning has been done.
