Sprawling Countries Find Coronavirus Hard to Contain

from The Wall Street Journal July 8, 2020

“All other things being equal, it’s harder to manage an epidemic in a large country than a small country.” - Maciej Boni

“Once in a while, one of these viruses wins the lottery.” - Maciej Boni

“It's like looking at the first 60 minutes of a hurricane and saying it's almost over. It's not almost over at all." - Maciej Boni

"While it is possible that this virus, like many other respiratory viruses, will not survive as readily in warm temperatures, it will be encountering a “completely susceptible” U.S. population, said Maciej F. Boni, an associate professor of biology at Penn State University."

Is the coronavirus outbreak as bad as SARS?

from LiveScience January 30, 2020

"I think that people should understand that even if most cases are mild, the level of severe infections still means that this coronavirus could affect millions and millions of Americans severely," Boni said.
