* This assumes that assays in development or currently undergoing regulatory evaluation prove to be accurate.
† The utility of antibody detection assays for diagnosing acute infections is probably very limited around the time of symptom onset, when viral shedding and transmission risk seem to be highest. Thus, although such tests may have a role among persons presenting late in the course of their infection, the potential for misuse is high.
