See in one minute how Covid-19 has torn across the U.S.

It’s been nearly nine months since the CDC confirmed the first case of Covid-19 in the U.S. In that short time, more than seven million people in the U.S. have been infected with the novel virus and more than 200,000 have died, the highest toll seen anywhere worldwide.

In the months since, Covid-19 cases have cropped up across the country, surging in some regions as they subsided at least somewhat in others. The hardest-hit areas have continued to shift — New York and New Jersy were early hotspots, followed by a dramatic uptick in cases in the south and western U.S. More recently, the virus has started taking a hefty toll on communities in the Midwest. Currently, Covid cases are on the rise in over 25 states.

This timelapse — developed by Microsoft AI for Health, Brown School of Public Health, and Harvard Edmond J. Safra Center for Ethics — shows how the virus has torn across the country since March, when community spread started to pick up.
