The death toll from the coronavirus has topped 560 in China, with more than 28,000 cases diagnosed worldwide. The rapid spread of the virus comes as the unprecedented lockdown of Chinese cities — home to 50 million people — enters its third week. In China, a newborn baby became the youngest person with the virus this week — diagnosed only one day after birth. Meanwhile, a cruise ship with thousands of people on board, including 428 Americans, has been quarantined off the shore of Japan. Twenty people on the cruise have tested positive for coronavirus on the ship so far. The cruise ship is now anchored off Yokohama Port, and none of the passengers are allowed to leave their rooms.
