Scrambling to keep the coronavirus at bay, officials ordered a cruise ship with about 3,500 people aboard to stay back from the California coast until passengers and crew can be tested, after a traveler from its previous voyage died of the disease and at least two others became infected. A Coast Guard helicopter lowered test kits onto the 951-foot (290-meter) Grand Princess by rope as the vessel lay at anchor off Northern California, and authorities said the results would be available on Friday, March 6, 2020. Princess Cruise Lines said fewer than 100 people aboard had been identified for testing. (Michele Smith via AP)
