The U.S. surpassed 100,000 confirmed cases of the novel coronavirus Friday, led by a continued jump in infections in New York and in new hot spots across the country.

While testing for the deadly respiratory virus hasn’t been uniform across America or globally, making accurate case counts hard to pin down, confirmed infections in the U.S. have doubled or tripled every three days for nearly a month.

Last Friday, the number of confirmed infections in the country exceeded 16,000, according to data compiled by Johns Hopkins University. By Tuesday, that figure was 55,000. Two days later, it had surpassed all other countries’ reported totals, with just over 85,000.

The pandemic has swiftly reverberated across the U.S., shutting schools, businesses, arenas and parks and silencing once-busy thoroughfares. A record 3.28 million workers applied for unemployment benefits last week. Hospital capacity in places like New York and Seattle has already passed a tipping point even as the health crisis continues to unfold.

President Trump signed a $2 trillion stimulus bill passed speedily by House lawmakers earlier Friday, the largest economic-relief package in history. Major U.S. stock indexes posted double-digit gains for the week, but remain down more than 20% in 2020.
