Inclusion criteria

Inclusion criteria: 1. Male and non-pregnant female subjects age =18 years 2. A Rapid Antigen Test (RAT) performed on an adequate specimen collected from an anterior nasal swab. A negative initial RAT may be repeated within one hour of obtaining a negative result. 3. Presence of fever at time of screening of =38.0 ºC (=100.4 ºF) taken orally, or =38.5 ºC (=101.2 ºF) taken rectally. For subjects with a positive RAT at the time of screening, a subject self-report of a history of fever or feverishness within the 24 hours prior to screening will also qualify for enrollment in the absence of documented fever at time of screening. For subjects with no positive RAT at screening, fever as defined above must be documented at time of screening 4. Presence of at least one respiratory symptom (cough, sore throat, or nasal symptoms) of any severity (mild, moderate, or severe) 5. Presence of at least one constitutional symptom (myalgia [muscle aches], headache, feverishness, or fatigue) of any severity (mild, moderate, or severe) 6. Onset of symptoms no more than 48 hours before presentation for screening 7. Written informed consent Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
