Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • patients aged 18 to 75 yrs of age presenting at a clinical site with symptoms diagnostic for an acute upper respiratory tract infection within the last 5 days

Exclusion Criteria:

  • patients who had chronic, recurring respiratory signs and symptoms due to conditions such as chronic allergic rhinitis, chronic sinusitis or chronic bronchitis which in the investigator's opinion, confounded interpretation of symptom ratings for the acute upper respiratory infection. Also excluded were patients with a fever greater than 101 degrees F.
