It's 4 a.m. in southern Minnesota and infectious disease physician Priya Sampathkumar has yet to go to bed.
While others sleep, the Mayo doctor works into the wee hours from her Rochester home, making phone calls in a frantic search for hospital beds half a world away and for much-needed oxygen for patients she's never met.
As the deadly coronavirus overwhelms her native India, Sampathkumar and her colleagues are fielding desperate calls from family, friends and friends of friends back home who have nowhere else to turn for help as COVID-19 cases surge there.
"The sheer numbers are overwhelming," Sampathkumar said Thursday. "There are more than 350,000 cases a day and it's likely 10 times that because the information coming out of the country is unreliable. Testing is hard to come by because so many are sick."
The devastating toll is documented daily in news reports — hospitals are swamped, oxygen supplies are dwindling and sick people are dying as they wait to be seen by doctors.
"I can't imagine what the images are like on TV because I'm hearing the pain in people's voices," Sampathkumar said.
Personally, she and her husband, Dr. Vincent Rajkumar, who also works at Mayo, feel fortunate because their families live in the southern part of India and have been isolated from the worst of the virus spread.
"We imposed a lockdown on them from here," Sampathkumar said.
