“It’s like Bob Dylan said: You don’t need to be a weatherman to know which way the wind blows,” says Scott, who works at the University of Texas at Austin, where his model is assessing whether changes in mobility patterns can predict coronavirus mortality.

However, while the death toll so far hasn’t risen to match, experts caution that the coronavirus has not lost its deadly kick. For one, the disease takes a while to kill, and humans take even more time to record the pandemic’s fatalities due to administrative red tape. The people who are dying today were likely infected three to four weeks ago. Read more >>
