Continue to, the antiviral pills increase the stakes of a missed prognosis, said Susan Butler-Wu, a scientific microbiologist at the Keck University of Medicine of the College of Southern California. “It’s not just recognizing my status,” she stated. “It’s now like, ‘Oh, this outcome could get me this genuinely lifesaving treatment.’”
Antigen assessments are frequently a lot less vulnerable to untrue positives, but those people faults will turn out to be an escalating issue when the virus becomes considerably less commonplace.
