A hospital's chief doctor died of the coronavirus after his husband begged him not to go to work.
Joseph Costa fell in with Covid-19 at the end of June before dying in the arms of his husband David R. Hart on Saturday.
The pair had been married for 28 years.
Mr Hart told The Washington Post : "I begged him not to go to work.
"When you see people without masks, you think, 'Are you out of your mind?'.
"This disease will take you out in a heartbeat."
Dr Costa headed up the intensive care unit at Mercy Medical Center in Baltimore before his death.
Mr Hart said his 56-year-old partner had a rare underlying autoimmune disorder.
Dr Costa's colleagues held a vigil as he died, placing their gloved hands on him.
"Those who cared for Joe were his best friends," Mr Hart told The Baltimore Sun.
"I keep thinking, now there is one less ICU doctor to care for pandemic patients in Baltimore."
Sister Helen Amos, executive chair of the hospital’s board of trustees, and David N. Maine, the hospital’s president and chief executive, praised Dr Costa in a statement.
They said: "Joe was more than a trusted colleague. He was also a true friend to many.
"He dedicated his life and career to caring for the sickest patients.
"And when the global pandemic came down upon us, Joe selflessly continued his work on the front lines - deeply committed to serving our patients and our city during this time of great need."
In the US more than four million people have tested positive for coronavirus.
Of those at least 145,000 have died, including at least 576 healthcare workers, according to The Centers for Disease Control and Prevention.
