‘A slow burn’: Coronavirus symptoms often linger before worsening

And sometimes, patients start to feel better before their health quickly deteriorates.

“That’s what we’re seeing with these patients who get a lot worse,” Lyn-Kew said. “They’re doing OK, and then all of a sudden they’re really fatigued, a lot more shorter of breath and having chest pains.”

In North Carolina, Dr. Christopher Ohl has also seen rapid, unexpected development of severe symptoms.

“They say, ‘Hey, you know, I think I’m getting over this,’ and then within 20 to 24 hours, they’ve got fevers, severe fatigue, worsening cough and shortness of breath,” said Ohl, an infectious disease expert and professor of medicine at the Wake Forest School of Medicine in Winston-Salem, North Carolina. “Then they get hospitalized.”
