Primary	Minimum Observed Plasma Concentration (Cmin) of Pimodivir	Cmin is the minimum observed plasma concentration. As per planned analysis, results are presented by age groups (65 to <= 85 years and 18 to <=64 years).	Pre-dose, 1, 2, 4, 6, 8, 10 and 12 hours post-dose on Day 3
Primary	Area Under the Plasma Concentration-time Curve From Time of Administration to 12 Hours After Dosing (AUC [0-12]) of Pimodivir	AUC (0-12) is the area under the plasma concentration-time curve from time zero to 12 hours after dosing of pimodivir. As per planned analysis, results are presented by age groups (65 to <= 85 years and 18 to <=64 years).	Pre-dose, 1, 2, 4, 6, 8, 10 and 12 hours post-dose on Day 3
Secondary	Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious AEs (TESAEs)	An adverse event (AE) is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non investigational) product. An AE does not necessarily have a causal relationship with treatment and therefore can be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with use of a medicinal product, whether or not related to that medicinal product. TEAEs were defined as AEs that were reported or worsened on after start of study drug(s) dosing through safety follow-up visit. A serious adverse event (SAE) is any untoward medical occurrence that at any dose resulting in any of following outcomes: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product.	Up to 28 Days
Secondary	Time to Influenza A Viral Negativity	Time to influenza A viral negativity was determined based on quantitative reverse transcription polymerase chain reaction (qRT-PCR). A participant was considered influenza A viral negative at the time point that the first negative nasal midturbinate (MT) swab was recorded (in days). Viral Load Limit of detection (LOD) = 2.18 log10 viral particles per milliliter (vp/mL). Results less than (<) limit of quantification (LOQ) and greater than (>) LOD (target detected) are imputed with 2.12 log10 vp/mL, results	Up to 14 Days
Secondary	Influenza Viral Load Over Time	Influenza viral load over time (Log 10 viral particles per milliliter [vp/mL]) was measured by qRT-PCR. Viral Load LOD = 2.18 log10 vp/mL. Results < LOQ and > LOD (target detected) are imputed with 2.12 log10 vp/mL and results	Baseline, Days 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14
Secondary	Rate of Decline in Viral Load	Rate of decline in viral load (Log10 viral particles per milliliter per day [log10 vp/mL/day]) during treatment was measured by qRT-PCR. Viral Load Limit of quantification (LOQ) = 2.18 log10 vp/mL, LOD = 2.05 log10 vp/mL. Results < LOQ and greater than > LOD (target detected) are imputed with 2.12 log10 vp/mL. Results	Up to Day 7
Secondary	Area Under the Plasma Concentration-time Curve (AUC) of Viral Load	Viral load AUC was determined by qRT-PCR assay of nasal swabs. Viral Load LOQ = 2.18 log10 vp/mL, LOD = 2.05 log10 vp/mL. Results	Baseline up to Day 8
Secondary	Percentage of Participants With Influenza Complications	Percentage of participants with following Influenza Complications: bacterial pneumonia (culture confirmed where possible), bacterial superinfections, respiratory failure, pulmonary disease (example, asthma, chronic obstructive pulmonary disease [COPD]), cardiovascular and cerebrovascular disease (example, myocardial infarction, congestive heart failure [CHF], arrhythmia, stroke) and all complications were reported.	Up to 28 Days
Secondary	Change From Baseline in Influenza Patient-Reported Outcome Questionnaire (FLU-PRO) Total Score	FLU-PRO assesses 32 influenza symptoms in each of the following body areas (domains): Nose, Throat, Eyes, Chest/Respiratory, Gastrointestinal and Body/Systemic . Participants rate each symptom on a 5-point ordinal scale, with higher scores indicating a more frequent sign or symptom. For 27 of the items, the scale is as follows: 0 ("Not at all"), 1 ("A little bit"), 2 ("Somewhat"), 3 ("Quite a bit"), and 4 ("Very much"). For 5 items, severity is assessed in terms of numerical frequency, that is (i.e), vomiting or diarrhea (0 times, 1 time, 2 times, 3 times, or 4 or more times); with frequency of sneezing, coughing, and coughed up mucus or phlegm evaluated on a scale from 0 ("Never") to 4 ("Always").The FLU-PRO total score is computed as a mean score across all 32 items comprising the instrument. Total scores can range from 0 (symptom free) to 4 (very severe symptoms).	Baseline, Days 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, and 33
Secondary	Time to Improvement of Vital Signs	Time to improvement of vital signs was defined as the time from first study treatment to when at least 4 of 5 symptoms (temperature, blood oxygen saturation, heart rate, systolic blood pressure, and respiration rate) had recovered, including normalization of temperature and blood oxygen saturation. Resolution criteria for vital signs: for Temperature: oral temperature less than or equal to (<=) 36.5 degree Celsius (C) for elderly and <=37.2 C for adults; for oxygen saturation: greater than or equal to (>=) 92 percent (%) on room air without supplemental oxygen; for respiratory rate: <= 24 per minutes; for heart rate: <= 100 per minutes and for systolic blood pressure: >= 90 millimeters of mercury (mmHg).
