The health ministry on Monday released guidelines for people who fear they have been infected with COVID-19 as officials said 99 more aboard the Diamond Princess cruise ship, including 43 Japanese citizens, had tested positive.

The newly identified people raised the total toll from the vessel to 454. A total of 3,711 passengers and crew were originally aboard the liner, but the total has dropped to about 3,100 as many elderly were allowed to disembark and some were transported to a hospital on land.

Meanwhile, many public events have been scrapped or scaled down due to fears of an epidemic.
