The coronavirus pandemic was still in its infancy a year ago when the eyes of the world — preoccupied by a burgeoning outbreak in China — turned to a quarantined cruise ship in Yokohama.

In January 2020, the world watched as mainland China struggled to contain a deadly new virus that appeared to be spreading from Wuhan, the capital of Hubei province.

On Feb. 5, the Diamond Princess docked in the port of Yokohama with more than 3,700 passengers and crew members who, upon arrival, were largely confined to their quarters for the next two weeks after a passenger tested positive for COVID-19 upon disembarking earlier in Hong Kong.
