US Disease Expert: Coronavirus Threat Means Lifestyle Changes VOA News One of the United States' top disease experts says Americans and Europeans should be prepared not to do the things they could do just a few months ago before the coronavirus outbreak. "It doesn't matter if you're in a state that has no cases or one case. You've got to start taking seriously what you can do now that if and when the infections will come," National Institute of Allergy and Infectious Diseases chief Anthony Fauci said Tuesday. "And they will come, sorry to say, sad to say." Fauci used hockey great Wayne Grtetzky as a metaphor for how to deal with an infectious disease -- Gretzky doesn't go where the puck is going, he goes where the puck is going to be. "We want to be where the infection is going to be as well as where it is," Fauci said. He said it is "no surprise" that the coronavirus outbreak appears to be subsiding in Asia while it grows in the United States and Europe, saying this has been the history of outbreaks of infectious diseases. The number of confirmed cases in the United States skyrocketed Tuesday to 975 -- up 400 in just one day. At least 30 have died. The coronavirus outbreak is affecting two major global institutions headquartered in the United States. .
