What’s all this talk about a “second wave” of U.S. coronavirus cases?
In The Wall Street Journal last week, Vice-President Mike Pence wrote in a piece headlined “There Isn’t a Coronavirus `Second Wave”’ that the nation is winning the fight against the virus.
Many public health experts, however, suggest it’s no time to celebrate. About 120,000 Americans have died from the new virus and there are worrisome recent increases in reported cases in the South and West.
But there is at least one point of agreement: “Second wave” is probably the wrong term to describe what’s happening.
“When you have 20,000-plus infections per day, how can you talk about a second wave?” said Dr. Anthony Fauci of the National Institutes of Health. “We’re in the first wave. Let’s get out of the first wave before you have a second wave.”
Clearly there was an initial infection peak in April as cases exploded in New York City. After schools and businesses were closed across the country, the rate of new cases dropped somewhat.
But “it’s more of a plateau, or a mesa,” not the trough after a wave, said Caitlin Rivers, a disease researcher at Johns Hopkins University’s Center for Health Security.
Scientists generally agree the nation is still in its first wave of coronavirus infections, albeit one that’s dipping in some parts of the country while rising in others.
“This virus is spreading around the United States and hitting different places with different intensity at different times,” said Dr. Richard Besser, chief executive of the Robert Wood Johnson Foundation who was acting director of the Centers for Disease Control and Prevention when a pandemic flu hit the U.S. in 2009.
Dr. Arnold Monto, a University of Michigan flu expert, echoed that sentiment.

“What I would call this is continued transmission with flare-ups,” he said.
