Despite the recent increase in testing across the country, widespread shortages in testing materials and workforce issues have crippled states' efforts to broadly test people. Many states have instead been forced to ration tests by giving priority to those who are hospitalized and populations, like the elderly, at high risk.

Maryland Gov. Larry Hogan, chairman of the National Governors Association, said at a Wednesday press conference now is "the worst possible time" to reopen, noting that his state needs to “exponentially expand testing capacity” before lifting its social distancing guidelines.

Other states' public health officials have also acknowledged testing isn’t at the level it needs to be to reopen the country, though many states are considering steps they can take to lift lockdown orders safely without widespread testing.

“The shortages are in testing supplies and shortages of PPE for people doing the tests,” said Mike Fraser, executive director for the Association of State and Territorial Health Officials. “There’s a big disconnect with what the White House says and what’s happening on the ground in states.”

Anthony Fauci, the U.S. government's top infectious disease expert, acknowledged existing issues with the testing supply chain but said they are being corrected.

“I know what it means when someone tells you 'Hey, you have what you need,' and you look around and you say 'Well, maybe you think I have what I need but I don't really have what I need,'" Fauci said at the White House briefing. "So we have to figure out, how do we close that gap?"
