RSV in Seniors: Symptoms, Risk Factors & Prevention Guide

Respiratory Syncytial Virus (RSV) is a leading cause of severe lower respiratory tract illness in older adults, particularly those with chronic cardiopulmonary conditions. While it typically causes mild cold-like symptoms in healthy adults, it can progress to bronchiolitis, pneumonia, and respiratory failure in vulnerable seniors.

Symptoms in Older Adults

• Early (URI-like): Rhinorrhea, nasal congestion, sore throat, cough, low-grade fever, chills
• Progression (LRTI): Worsening productive cough, dyspnea, wheezing, chest tightness, hypoxemia
• Systemic: Fatigue, myalgia, anorexia, malaise
• Atypical in frail/demented: Confusion, lethargy, falls, functional decline, reduced oral intake—may be the only signs
• Severe complications: Bronchiolitis, pneumonia, acute respiratory failure, exacerbation of COPD/CHF/asthma, secondary bacterial infection

High-Risk Factors for Severe RSV

• Age ≥65 (risk increases with each decade)
• Chronic heart disease (HF, CAD)
• Chronic lung disease (COPD, asthma, pulmonary fibrosis)
• Diabetes mellitus
• Immunocompromise (malignancy, transplant, immunosuppressive meds, HIV)
• Frailty, functional dependence, nursing home residence
• Recent hospitalization (past year)
• Neurologic conditions impairing secretion clearance

Treatment

Supportive care is the mainstay:

• Rest, hydration, nutrition
• Acetaminophen/NSAIDs for fever/pain
• Cough suppressants/expectorants as needed
• Bronchodilators (SABA/LAMA) for wheezing/airflow obstruction
• Oxygen therapy for hypoxemia
• Non-invasive ventilation (BiPAP) or intubation for respiratory failure
• Antibiotics only if bacterial co-infection suspected
• Monitor and manage underlying conditions (diuretics for HF, steroids for COPD/asthma flare)

Prevention

• RSV Vaccination (≥60 years): Arexvy® (RSVPreF3) or Abrysvo® (RSVpreF)—single dose, ~80–85% efficacy vs. RSV-LRTI. Shared clinical decision-making with provider.
• Annual influenza vaccine + updated COVID-19 booster.
• Pneumococcal vaccines (PCV20 or PCV15+PPSV23) per schedule.
• Frequent handwashing, surface disinfection
• Avoid sick contacts; mask in crowded indoor settings during RSV season
• Optimize chronic disease control
• Adequate sleep, nutrition, physical activity as tolerated

When to See a Doctor

• Difficulty breathing, rapid breathing, wheezing, chest pain
• Confusion, excessive drowsiness, inability to arouse
• Fever >102°F (39°C) or fever persisting >3 days
• Inability to keep fluids down, signs of dehydration
• Worsening of known heart/lung condition

RSV is a serious but increasingly preventable threat for seniors. Vaccination, combined with vigilance and chronic disease optimization, offers the best protection.
