Brief summary
The purpose of this study is to evaluate the positivity rate of respiratory syncytial virus (RSV), influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in high-risk participants presenting with acute respiratory infections (ARIs) in outpatient settings during the influenza/RSV season and to evaluate the association between lower respiratory tract disease (LRTD) and ARI-related hospitalization in participants positive for RSV.
Detailed description
Lower respiratory tract infections (LRTIs) are a major cause of mortality and morbidity worldwide with 2.3 million deaths in 2016 alone among all age groups, making it the sixth leading cause of mortality. The current study aims to assess the burden of RSV infections among adult participants presenting in outpatient settings, who are at high risk of complications or progression to severe disease due to their age or pre-existing comorbidities. Regional data from the United States (US), Europe, Middle East, and Asia (EMEA) and Asia-Pacific (APAC) will provide evidence on local RSV morbidity, mortality, medical resource utilization (MRU), standard of care, and quality of life in adults participants. A subset of participants positive for influenza virus and/or SARS-CoV-2 will also be enrolled, to allow for a comparative assessment of disease burden between the 3 viral respiratory pathogens. No study drug will be involved in this study. The total duration of the study for each participant will be a maximum of 3 months (+-1 week) from the date of enrollment. Safety will be assessed in the form of adverse events and serious adverse events related to study devices or procedures and for deaths regardless of causality.
Interventions
DIAGNOSTIC_TESTNasal Swab Sample
Nasal swab sample will be used to screen participants for detection of viral pathogens. No intervention or study drug will be administered as part of this study.

Inclusion criteria
* Present to the general physician (GP)/specialist outpatient settings/respiratory clinics or in Emergency department (ED) settings with symptoms suggestive of a diagnosis of Acute Respiratory Infections (ARI) * For inclusion in the home-based follow-up phases, must test positive for respiratory syncytial virus (RSV) and/or influenza and/or Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) per a molecular-based diagnostic assay (polymerase chain reaction \[PCR\]-based) using a nasal swab (nasopharyngeal or similar) sample. Co-infections are permitted to be enrolled in the study * Must be able to read, understand, and complete questionnaires * Must be willing to provide verifiable identification, has means to be contacted and to contact the investigator during the study * Willing and able to adhere to the specifications in this protocol
Exclusion criteria
* Has a clinical condition other than those as specified in study protocol which, in the opinion of the investigator, could prevent, confound, or limit the protocol-specified assessments * Received an investigational drug (including investigational vaccines) within 3 months before the start of the study or the first data collection time-point * Is currently enrolled or plans to participate in another investigational study on RSV, influenza or SARS-CoV-2 during the current study * Is, in the opinion of the investigator, unlikely to adhere to the requirements of the study, or is unlikely to complete the full course of observation * Cannot communicate reliably with the investigator
