The cruise ship carrying at least 21 people infected with the coronavirus passed under the Golden Gate Bridge as federal and state officials in California prepared to receive thousands of people on the ship that has been idling off the coast of San Francisco. Personnel covered head to toe in protective gear Monday woke up passengers on the Grand Princess to check whether they were sick. (AP Photo/Eric Risberg)
