At least 44 Americans who were on a now-quarantined cruise ship in Japan have tested positive for COVID-19, according to Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health. Fauci confirmed the number of Americans infected with the disease to TIME and noted that the count was still “in flux” and likely to be “more than that.” Fauci said in an interview that aired Sunday with CBS News’ Face the Nation that 40 Americans who were traveling on the Diamond Princess “have gotten infected” and are “going to be in hospitals in Japan” as evacuation plans to get Americans on the vessel back home are underway. “People who have symptoms will not be able to get on the evacuation plane,” Fauci said in the Face the Nation interview.
