| Measure | Time frame |
|---|---|
| 1.Viral tests (1) Residual virus "Nasal swab" will be taken on Day 1, 3, and 5 (or discontinuation date) to conduct the following tests: (If sinuses are too dry for sample collection, throat swabs may be substituted. Day 6 samples will be accepted if subjects are not available or if a holiday coincides with Day 5.) * Viral isolation and identification (PCR) * Rapid diagnostic test for influenza (Day 3, Day 5 (or discontinuation date)) 2. Influenza symptoms (1) Time of fever clearance Instruct subjects to record their body temperature from the start date of administration (Day 1) to Day 5. Fever clearance time is measured as the time from drug administration until the reduction of body temperature below 37.5C. (If the temperature relapses above 37.5C, fever clearance time will be considered as the last time it took for the body temperature to drop below 37.5C). (2) Other symptoms Instruct subjects to keep a symptom diary from the start date of administration (Day 1) until Day 5 (or discontinuation date): * nasal discharge, nasal obstruction, sore throat, muscle ache, joint pain, malaise or fatigue, and headache. 3) Blood count, CRP and cytokine (1) Changes in cytokine levels Determine the blood count (WBC fraction), CRP, cytokine (IL-1, IL-6, IL-8, IL-10, TNF-a, IFNa2) levels in the blood from the start date (Day 1, prior to test drug administration), Day 3, and Day 5 (or discontinuation date). | — |
