Respiratory syncytial virus (RSV) is widely recognized as a common cause of respiratory illness in children, but its impact on adults, particularly older adults and those with underlying health conditions, requires equal attention. Family physicians are on the front lines of recognizing and managing RSV in this vulnerable population.
RSV in Adults: An Overlooked Threat
Each year, RSV contributes to significant morbidity and mortality among older adults. Adults aged 50 and older, and those living with chronic conditions, such as chronic obstructive pulmonary disease, coronary artery disease, congestive heart failure, diabetes, and weakened immune systems, are at an increased risk of severe RSV disease, hospitalization, and death.
Studies have shown that RSV-related outcomes in older adults are often comparable to influenza, underscoring the importance of awareness and prevention.
Recognizing RSV in Adults
Symptoms in adults can mimic other respiratory viruses, including cough, fever, congestion, fatigue, and wheezing. However, RSV can progress to a serious lower respiratory tract infection such as pneumonia and bronchiolitis. It may also exacerbate underlying chronic conditions, leading to worsening heart or lung disease.
- Maintain vigilance during RSV season
- Consider RSV in the differential diagnosis for adults with worsening respiratory symptoms
- Recognize that hospitalization and complications are especially likely in older adults with comorbidities.
Preventing RSV: Vaccination and Education
The recent availability of RSV vaccines for older adults provides an important tool in protecting patients. Centers for Disease Control and Prevention (CDC) guidance recommends a one-time RSV vaccine for adults age 75 and older, and for ages 50-74 at increased risk. This guidance is also supported by the American Academy of Family Physicians in its Fall 2025-26 Immunization Recommendations.
- Discussing RSV vaccination with eligible patients
- Educating patients that RSV is not just a childhood illness but a significant health risk for older adults
- Reinforcing preventive behaviors, such as hand hygiene, masking during respiratory virus season, and avoiding contact with sick individuals.
Why It Matters
For older adults and those with chronic conditions, RSV is a serious health threat. As trusted clinicians, family physicians can help reduce the burden of RSV-related hospitalizations and complications by integrating awareness, prevention, and vaccination into everyday patient care.
