Summary

This study will track 1,000 adults aged 60 and older who are hospitalized in Vietnam with breathing problems or worsening heart/lung conditions. Researchers want to find out how many of these cases are caused by RSV (respiratory syncytial virus) and which types of the virus are involved. The goal is to better understand the role of RSV in severe illness among older adults.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors understand how often RSV causes severe illness in older adults in Vietnam, guiding future prevention efforts.
What could go wrong
This is an observational study, not a treatment trial. It will not test any drug or vaccine, so it cannot directly improve health. Results may not apply to other countries.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: To be enrolled in the study, participants must meet all inclusion criteria: 1. Individuals ≥ 60 years old at the time of screening (calculated from the date of birth to the date of screening) 2. ARI or exacerbation of cardiopulmonary diseases diagnosed at the time of admission. ARI or ARI-compatible symptoms were defined as either: * New onset or increase from baseline of: nasal congestion, rhinorrhea, sore throat, hoarseness, cough, sputum production, dyspnea, wheezing, hypoxemia, or * Admitting diagnosis suggestive of ARI (e.g., pneumonia, upper respiratory infection, bronchitis, influenza, cough, viral respiratory illness, respiratory distress, or respiratory failure), or * Admitting diagnosis was the exacerbation of an underlying cardiac or pulmonary disease involving acute respiratory symptoms within the previous 2 weeks (e.g., congestive heart failure \[CHF\], chronic obstructive pulmonary disease \[COPD\], or asthma exacerbation). 3. The participant agrees to voluntarily participate in this study. Exclusion Criteria: To be enrolled in the study, participants must have none of the exclusion criteria: 1. Symptom onset \> 6 days prior to screening date 2. Acute symptoms confirmed to be unrelated to infection or as assessed by the investigator 3. Admission to any hospital within the 30 days preceding the screening date 4. Previously enrolled in the study in the last 45 days
