Infected But Feeling Fine

New York Times: “As many as 25 percent of people infected with the new coronavirus may not show symptoms, the director of the Centers for Disease Control and Prevention warns — a startlingly high number that complicates efforts to predict the pandemic’s course and strategies to mitigate its spread.”

“In particular, the high level of symptom-free cases is leading the C.D.C. to consider broadening its guidelines on who should wear masks.”

“Researchers do not know precisely how many people are infected without feeling ill, or if some of them are simply presymptomatic. But since the new coronavirus surfaced in December, they have spotted unsettling anecdotes of apparently healthy people who were unwitting spreaders.”
