Two crises collided this spring in Michigan. The state was already under a coronavirus lockdown when a catastrophic storm hit and a pair of dams failed, flooding the city of Midland.

The local hospital, MidMichigan Medical Center — Midland, hired a disaster recovery company to clean up the mess, including a water-logged basement and morgue. More than 100 workers — many of them recent immigrants — were brought from as far away as Texas and Florida. Bellaliz Gonzalez was one of them.

Dr. Basim Ali graduated at the top of his medical school class in Pakistan and landed a residency at a renowned teaching hospital in Texas, where he'll be on the front lines of one of the worst COVID-19 outbreaks in the U.S.

"There's obviously some degree of anxiety about what that's going to be like," Ali said by phone from Karachi before coming here. "But there's also this understanding that this is what we signed up for."

When nurses and doctors across the country were struggling to treat coronavirus patients without enough protective gear, and the federal government was scrambling to find those supplies, Quedon Baul saw an opportunity.

His three-person company in McKinney, Texas, distributes medical supplies but didn't have much experience with face shields. Still, he landed two government contracts worth up to $20 million to deliver the personal protective equipment. He couldn't meet the first deadline, so he found subcontractors to do the job.

Coronavirus testing in the U.S. has run into a number of snags, from a lack of nasal swabs to not enough chemicals needed to run the tests.

Now there's a new bottleneck emerging: A shortage of the machines that process the tests and give results.

Civilian labs and the Pentagon say they've had trouble getting the sophisticated, automated machines that can run hundreds of diagnostic tests at once. Three machine manufacturers — Hologic Inc., Roche and Abbott Laboratories — have confirmed to NPR that demand is outstripping supply.

As hospitals were overrun by coronavirus patients in other parts of the world, the Army Corps of Engineers mobilized in the U.S., hiring private contractors to build emergency field hospitals around the country.

The endeavor cost more than $660 million, according to an NPR analysis of federal spending records.

But nearly four months into the pandemic, most of these facilities haven't treated a single patient.

When Carlos Mejia-Bonilla was detained by immigration authorities a few years ago, he told the health care staff at the Hudson County Correctional Facility in New Jersey that he was taking medicine for a range of conditions, including diabetes, anemia, high blood pressure and cirrhosis of the liver.

Ten weeks later, he died of gastrointestinal bleeding.

Frustration with stay-at-home orders is mounting in many parts of the country. In Colorado, protesters gathered Sunday afternoon on a hillside in front of the state capitol in Denver.

"I'm watching businesses close. I'm watching friends lose their incomes," protester Deesa Hurt told Colorado Public Radio. "We just want to reopen Colorado. That's all we want."

In recent days, the Trump administration has organized dozens of flights to deliver surgical masks and other critical medical supplies around the country, working with a half dozen major medical distributors to get those supplies "to the right place at the right time."

But if your state isn't considered the right place, that system can be frustrating.

"When you look at those five or six national distributors, Montana is sure as heck not getting much luck out of them," Gov. Steve Bullock said in an interview.

From the hospital where he works in South Carolina, Dr. Kiran Nagarajan has been watching the coronavirus crisis explode in other parts of the country. But, like many other immigrant doctors, he can't do anything about it.

"There's a dire need of physicians especially in places like New York, New Jersey," Nagarajan said. "I wish I can go and help there."

U.S. authorities face growing calls to shutter all of the nation's immigration courts, and to release detained immigrants who do not pose a threat to public safety after an ICE detention center worker tested positive for the coronavirus.

Immigration and Customs Enforcement reported for the first time this week that one of its workers has the virus that causes COVID-19. ICE also says there are no confirmed cases of coronavirus among its more than 37,000 detainees nationwide.

President Trump plans to seal off the U.S-Mexico border to migrants under a law intended to protect the country from communicable disease — a move that comes as the U.S. immigration system grinds to a halt in response to the growing coronavirus pandemic.

At a press conference Wednesday, Trump said the southern border would not close completely. But the move would allow the administration to quickly deport asylum-seekers and other migrants who cross the U.S.-Mexico border illegally without due process.
