Passengers and crew who travelled on several cruise ships during the 2019–20 coronavirus pandemic were found to be infected with the novel SARS-CoV-2 virus that caused the pandemic. Although most ships involved did not have substantial spread of the disease, on the British-registered Diamond Princess, there was substantial spread of the virus amongst the passengers and crew. The ship was quarantined in February 2020 for nearly a month with about 3,700 passengers and crew on board; around 700 people were infected in the incident, and eight died.
