Primary Outcome Measures
NameTimeMethod
Burden as Measured by Medical Resource Utilization, Complications, Mortality, Re-hospitalizations and Post Discharge Care InformationUp to 6 months after discharge

Number of participants with medical resource utilization, complications, mortality, re-hospitalizations and post discharge care information will be assessed.

Secondary Outcome Measures
NameTimeMethod
Number of Participants Without Presenting Symptoms of Acute Respiratory Tract Infection (ARTI)During hospitalization (up to maximum 12 months)

Number of participants without presenting symptoms among participants with PCR-confirmed RSV, influenza A, or hMPV infections of ARTI will be reported.

Participant's Clinical Status Assessed by Hospital Recovery Scale (HRS)Baseline, Day 4, Day 6 and Day 14

The hospital recovery scale assesses a participant's clinical status. The scale provides 6 mutually exclusive conditions ordered from best to worst: 1) not hospitalized; 2) non-ICU hospitalization, not requiring supplemental oxygen; 3) non-ICU hospitalization, requiring supplemental oxygen; 4) admitted to the ICU, not requiring invasive mechanical ventilation; 5) requiring invasive mechanical ventilation; and 6) death.

ReSVinet score used at Time of Admission to the Hospital in Infants/Children, and Relevance on MRU by Type of Respiratory PathogenAt Admission (Day 1)

ReSVinet scale is based on seven parameters (feeding intolerance, medical intervention, respiratory difficulty, respiratory frequency, apnoea, general condition, fever) which are assigned different values (from 0 to 3) for a total of 20 points. Higher scores indicate higher severity.

Number of Participants in Various Subgroups of Hospitalized Patients by Type of Respiratory PathogenDuring hospitalization (up to maximum 12 months)

Number of participants in various subgroups (eg, comorbidities, premature infants, elderly, immunocompromised) of Hospitalized Patients by Type of Respiratory Pathogen (RSV, influenza A, and hMPV in adults and RSV and hMPV in infants/children less then or equal to (\<=) 5 years of age) will be characterized.

CRB-65 Scoring System at Admission to the Hospital for Adults with Lung Disease and the Relevance on Medical Resource Utilization (MRU) by type of Respiratory PathogenAt admission (Day 1)

Confusion, respiratory rate greater than or equal to (\>=) 30/minute, low systolic less than (\<) 90 millimeter of mercury (mm Hg) or diastolic less than or equal to (=\<) 60 mm Hg blood pressure, age \>= 65 years (CRB-65) scoring system at admission to the hospital for adults with lung disease and the relevance on MRU by type of Respiratory Pathogen will be assessed. CRB-65 Scale ranges from 0 to 4. Score 0 = Very low risk of death, Score 1 and 2 = Increased risk of death and 3 or 4 = High risk of death.

Simplified Acute Physiology Scores 3 (SAPS 3) in Adults at ICU Admission and the Relevance on MRU by Type of Respiratory PathogenAt ICU admission (up to maximum 12 months)

The SAPS 3 consists of 20 variables: age, co-morbidities, use of vasoactive drugs before ICU admission, intrahospital location before ICU admission, and length of stay in the hospital before ICU admission, reason(s) for ICU admission, planned/unplanned ICU admission, surgical status at ICU admission, anatomic site of surgery, and presence of infection at ICU admission and place acquired, lowest estimated Glasgow coma scale, highest heart rate, lowest systolic blood pressure, highest bilirubin, highest body temperature, highest creatinine, highest leukocytes, lowest platelets, lowest hydrogen ion concentration (pH), and ventilatory support and oxygenation. Score varies from a minimum of 0 points to a maximum of 217 points. Higher scores indicate higher severity.

Medical Resources Utilization by Estimated Glomerular Filtration Rate (eGFR)Baseline

MRU in adults by eGFR at baseline that is before hospitalization will be collected. The glomerular filtration rate is an indicator of renal function and is calculated based on serum creatinine.

Levels of Neutrophils During HospitalizationDuring hospitalization (up to maximum 12 months)

Levels of Neutrophils during hospitalization will be reported.

Number of Participants (infants/children) with RSV and hMPV InfectionDuring hospitalization (up to maximum 12 months)

Number of infants/children participants with RSV and hMPV infection will be reported.

Patient JourneyDuring hospitalization and up to 6 months after discharge

The number of patients admitted to different hospital-locations (ED/ER department, Ward, Outpatient clinic, ICU, Other), their provenances, the number of patients being transferred to ICU and the number of patients being thereafter re-hospitalized will be assessed.

Change of National Early Warning Score (NEWS) for Adults at Admission, Day 3, and Day 6At admission (Day 1), Day 3, and Day 6

The NEWS provides guidance for 3 scores: Low score (1-4) should prompt assessment by a competent registered nurse who should decide if a change to frequency of clinical monitoring or an escalation of clinical care is required; Medium score (5-6) should prompt an urgent review by a clinician skilled with competencies in the assessment of acute illness; and High score (7 or more) should prompt emergency assessment by a clinical team/critical care outreach team with critical-care competencies.

Levels of C-Reactive Protein During HospitalizationDuring hospitalization (up to maximum 12 months)

Levels of C-Reactive Protein during hospitalization will be reported.

Symptoms of Participants Presenting at HospitalAt admission (Day 1) and at discharge

Symptoms of Participants Presenting at Hospital (outpatient clinic, emergency room/emergency department \[ER/ED\], or general ward) and at discharge will be assessed.

Medical Resources Utilization by Type of Virus InfectionBaseline

MRU in adults by type of virus infection (RSV A, RSV B, influenza A, influenza B, hMPV, any other virus infection if available) at baseline that is before hospitalization will be collected.

Levels of White Blood cell During HospitalizationDuring hospitalization (up to maximum 12 months)

Levels of White Blood cell Count during hospitalization will be reported.

Number of Participants (Adults) with RSV, Influenza A and hMPV InfectionsDuring hospitalization (up to maximum 12 months)

Number of Adult participants with RSV, Influenza A and hMPV Infections will be reported.

Number of Participants with Respiratory Infections of Nosocomial Origin With or Without Presenting SymptomsDuring hospitalization (up to maximum 12 months)

Number of participants with respiratory infections of nosocomial origin with or without presenting symptoms among participants with PCR-confirmed RSV, influenza A, or hMPV infections will be reported.

Criteria Applied for the Index-Hospitalization, Transfer to ICU, Discharge From HospitalAt admission, at ICU admission, at discharge (up to maximum 12 months)

The distribution of the primary reasons for the index-hospitalization, the distribution of the primary reasons for ICU transfer, the distribution of the criteria used to discharge from the index-hospitalization (including hospital recovery scale (HRS) and oxygen saturation) will be assessed.

Acute Physiologic and Chronic Health Evaluation (APACHE II) Scores in Adults at ICU Admission and the Relevance on MRU by Type of Respiratory PathogenAt ICU admission (up to maximum 12 months)

The APACHE II is a validated severity of disease classification system. It uses a point score based on initial values of 12 routine physiologic measurements (temperature, mean arterial pressure, heart rate, respiratory rate, oxygenation, arterial pH, serum sodium, potassium, and creatinine, hematocrit, white blood cell count, Glasgow coma score), age, and previous health status to provide a general measure of severity of disease. An increasing score (range 0 to 71) is closely correlated with subsequent risk of hospital death for intensive care admissions.

Levels of Procalcitonin During HospitalizationDuring hospitalization (up to maximum 12 months)

Levels of Procalcitonin during hospitalization will be reported.

Levels of Viral Load During HospitalizationDuring hospitalization (up to maximum 12 months)

Levels of Viral Load during hospitalization will be reported.
