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.
