Global cases of the coronavirus hit a new milestone of 2.5 million Tuesday, as key U.S. states continued a phased restart of their economies, even as the pandemic continued to take a toll on America.

Globally, deaths have surpassed 171,000, while in the U.S. that number jumped above 42,000 Tuesday — setting an average of 2,000 per day in the past several days. The world’s largest economy still accounts for more confirmed COVID-19 cases than any other country, with over 788,000 infected.

Gov. Andrew Cuomo said Tuesday that while the state is far ahead, per capita, in testing, it is still hard pressed to provide adequate testing levels to justify relaxing restrictive stay-at-home orders that have shut down the state. Other governors have also pushed back on restarting without an ability to assess who’s been infected, or developed immunity.

He added that he’s troubled by talk of reopening as the number of coronavirus cases are still growing. 

“And in fact, just three days ago, we’re finally able to test every person who comes in with symptoms of COVID-19. That’s a new phenomenon now — three months after the first case. So, I’m extremely concerned with all the talk of charging ahead with reopening when we truly do not have a grasp of how many cases are actually out there.” 

Amid a tussle with the Trump administration over testing resources, Gov. Larry Hogan circumvented the federal hold over supplies in the country and received 500,000 testing kits from South Korea, which has been widely praised for its aggressive COVID-19 response.

The WHO addressed a controversy over the origins of the virus, which some have speculated came from a lab in Wuhan, the epicenter of the global outbreak.
