Nonetheless, the antiviral drugs increase the stakes of a missed prognosis, mentioned Susan Butler-Wu, a medical microbiologist on the Keck College of Medication of the College of Southern California. “It’s not simply figuring out my standing,” she mentioned. “It’s now like, ‘Oh, this consequence may get me this actually lifesaving treatment.’”
