The worldwide number of COVID-19 cases is quickly approaching the 2 million mark, including more than 117,000 people who have died, according to a COVID-19 dashboard created by Johns Hopkins University’s Whiting School of Engineering.
The 2009 H1N1 flu pandemic that Tedros referenced is estimated to have infected more than 60 million people in the U.S., according to the Centers for Disease Control and Prevention. The agency estimates the virus killed nearly 12,500 Americans in the span of one year. Nearly twice that number have already died from COVID-19 in the U.S., where some 570,000 people are confirmed to be infected.
