WEDNESDAY, July 29, 2020 (HealthDay News) -- The fate of more than 3,600 quarantined passengers and crew on the cruise ship Diamond Princess made headlines in the early weeks of the coronavirus pandemic in February.
The first known case of coronavirus infection on the Diamond Princess was reported Feb. 1 in an ill 80-year-old passenger who left the ship in Hong Kong on Jan. 25.
One prior study had also estimated that quarantine and other public health measures "prevented more than 2,000 additional cases" aboard the Diamond Princess, compared to doing nothing at all, Kuroda's group noted.
In the new study, the Japanese team sought to determine the origins of the cruise ship outbreak.
The genetic analysis suggests "that there was a single introduction of SARS-CoV-2, which disseminated among passengers on the ship through possible mass gathering events in the recreational areas," according to the study.
