This followed confusion after a passenger traveling through Malaysia was said to have tested positive for coronavirus. That occurred subsequent to Cambodian health officials clearing everyone following screenings. The US woman, 83, was hospitalized in Kuala Lumpur.
Now it’s in doubt whether she had coronavirus. Perhaps her Malaysia test was a false positive. The New York Times said CDC was not able to confirm that, but cited an independent expert who said the agency likely had information indicating as such.
During a news conference last Friday, Malaysia's Deputy Prime Minister Wan Azizah Wan Ismail said the woman subsequently was tested repeatedly for COVID-19, with the results showing she is clear of the virus though she remained hospitalized.
The same day, the Cambodian government expressed doubt over the accuracy of the woman’s initial positive test by Malaysian authorities.

In a letter to Westerdam passengers, Holland America said that based on the information of the single case, CDC 'does not recommend isolation or quarantine for guests returning home from Westerdam.'
The line has consistently stated there was no evidence or indication of any suspected coronavirus cases on board.
