Respiratory Syncytial Virus (RSV) is a common yet highly contagious respiratory virus that can cause severe illness in older adults and those with underlying health conditions. Discussions led by Drs. Forest Arnold and Edward Walsh provide valuable insights into the impact of RSV on adult health, emphasizing the importance of understanding the risk factors and potential complications associated with the virus.

Risk Factors and Complications of RSV in Adults
Recent studies have identified several risk factors for severe RSV infection in adults. These include chronic respiratory and heart diseases, diabetes, chronic kidney diseases, and cardiovascular diseases. The severity of RSV is particularly evident in individuals in their 60s, 70s, and 80s, with hospitalization rates peaking in those aged 85 and older. For adults 65 years and older, as well as for adults with chronic heart or lung disease, and weakened immune systems, RSV can be life-threatening.
Furthermore, a study aimed at understanding the correlation between RSV and inflammatory bowel disease (IBD) found that adult patients with IBD and RSV infection are at an increased risk for hospitalization. This highlights the potential benefit from the new RSV vaccine recommended for adults aged 60 years and older.
Impact of the COVID-19 Pandemic on RSV
The COVID-19 pandemic has disrupted the predictability of RSV outbreaks, further complicating its management. Healthcare workers continue to be at an increased risk of acquiring RSV, and nosocomial transmission remains a significant concern. This disruption of RSV outbreaks during the pandemic has emphasized the importance of shared decision-making in vaccination and the need to address low vaccine uptake and awareness.
Prevention Measures and Challenges in RSV Prevention
Preventive measures against RSV include staying up to date on vaccinations, working with healthcare teams to control chronic lung disease, avoiding sick individuals, and practicing good hygiene. Nevertheless, there are challenges in RSV prevention, such as vaccine hesitancy, supply chain issues, and a lack of awareness about RSV and its potential severity in adults.
In 2023, two vaccines and a monoclonal antibody were approved for the prevention of RSV related illness. The vaccines are reported to be more than 80% effective at preventing severe RSV disease. However, there are contraindications and potential adverse effects, including pain at the injection site, headaches, myalgia, nausea, and in some cases, severe neurologic conditions like Guillain-Barré syndrome and atrial fibrillation.
Moving Forward: Reducing the Impact of RSV
Efforts to increase awareness, enhance prevention measures, and promote vaccine uptake are crucial to reducing the impact of RSV in adults. The Florida Department of Health, for example, conducts surveillance to support clinical decision-making for prophylaxis of premature infants and has established regional RSV seasons based on activity thresholds provided by the CDC.
In conclusion, understanding the risk factors, complications, and preventive measures of RSV in adults is essential to mitigating its impact on adult health. It is crucial that we continue to promote awareness, enhance vaccination rates, and adopt preventive measures to combat this potentially severe respiratory virus.
