Some 700 of a total of 3,711 people on board were infected with the coronavirus, seven of whom died.
This is the genetic analysis published last week. She reveals that one person is undoubtedly the source of the approximately 700 infections on the Diamond Princess cruise ship, one of the earliest outbreaks of the Covid-19 pandemic. In this study published in the American journal PNAS, a team from the Japan Institute of Infectious Diseases reports that they sequenced the genome of the virus collected from 148 of
passengers and crew of the vessel.
These people were quarantined by the Japanese authorities for 14 days at Yokohama port on February 3, after an 80-year-old passenger who had previously disembarked in Hong Kong tested positive on February 1.

The saga of the quarantine of more than 3,600 passengers and crew was followed around the world, Japan was criticized for not preferring to evacuate the ship, while countries like the United States argued about the relative risks of repatriating their nationals.
Approximately 700 infections in 3711 people
Some 700 of a total of 3,711 people on board were infected with the coronavirus, seven of whom died. A study of data from this polluted environment that has concluded has led to the first estimates of mortality from sars coronavirus (1.2%) and the proportion of asymptomatic individuals (18%), with at least thirty studies with the dumpster being made since February, the website says covid19primer.com page.
The new genetic analysis shows that all the viruses shared the same mutation, suggesting that “the spread of SARS-CoV-2 aboard the Diamond Princess began as a single introduction event, before the start of the quarantine,” the researchers concluded. Japanese scientists. The infections likely began during large gatherings in common areas, “where travelers danced, sang, shopped and attended plays.

According to the study authors, this demonstrates the interest of genetic research in understanding the infection process of a constantly replicating mutant virus, which still makes it possible to reconstruct the equivalent of a family tree and understand precautions that might have helped. to reduce infection.
