The authors wrote: "SARS-CoV-2 RNA 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".
However, Dr Derek Gatherer, an infectious disease specialist at Lancaster University, is not convinced the coronavirus can stay on surfaces for 17 days.
The CDC report also said that passengers on the Diamond Princess mainly spread the virus before the ship went into quarantine, but infections among the crew peaked afterwards. "We couldn't say for sure unless someone did viral culture".
Health officials have warned repeatedly that people can catch the illness by touching a contaminated surface and then touching their face.
Perth tourism pioneer James Kwan was the first Australian to be killed by the disease after he contracted the virus on the Diamond Princess cruise ship off Japan.
Coronavirus survived for 17 days in empty cruise ship cabins, CDC report says
The report, published Monday, examined data from the Diamond Princess cruise ship, which was quarantined after passengers began testing positive for COVID-19 in February.
On Thursday, seven of 800 foreign passengers on board the German-operated MV Artania tested positive for COVID-19, and two more were unwell.
The CDC's report comes after previous studies suggested the coronavirus may be able to live on some surfaces - namely glass, metal or plastic - for up to nine days, per a study published in The Journal of Hospital Infection which analyzed other human coronaviruses (e.g., SARS, MERS).
"The quarantine was not justified, and violated the individual rights of the passengers while allowing the virus to literally pick them off one-by-one", Dr. Amesh Adalja, who works at the Johns Hopkins Center for Health Security, told Business Insider's Morgan McFall-Johnsen.
What is certain, the CDC says, is that cruise ships are "often settings for outbreaks of infectious diseases due to their closed environment and contact between travelers from many countries", according to the report.
