As the weather shifts and respiratory illnesses become more prevalent, understanding and protecting against Respiratory Syncytial Virus (RSV) is crucial. RSV is a common respiratory virus that typically causes mild, cold-like symptoms, but it can pose a serious threat to infants, older adults, and individuals with underlying health conditions. Recent advancements in immunization offer new layers of defense against this widespread virus.
While most people recover from RSV within a couple of weeks, the virus is the leading cause of infant hospitalization in the United States, according to the Centers for Disease Control and Prevention ([CDC](https://www.cdc.gov/vaccines/hcp/by-disease/rsv.html)). The impact of RSV extends beyond infancy, with older adults also facing a heightened risk of severe illness. Understanding the available preventative measures is key to safeguarding vulnerable populations.
What is RSV and Who is at Risk?
RSV is a common respiratory virus that infects the lungs and breathing passages. Symptoms often mimic a common cold, including a runny nose, decreased appetite, cough, and fever. However, in severe cases, RSV can lead to bronchiolitis (inflammation of the little airways in the lungs) and pneumonia. The virus is highly contagious and spreads through close contact with infected individuals, respiratory droplets produced during coughing or sneezing, and by touching contaminated surfaces.
Infants, particularly those under six months old, are at the highest risk of severe RSV disease. Premature babies and those with congenital heart or chronic lung diseases are also more vulnerable. Older adults, especially those with weakened immune systems or underlying conditions like heart or lung disease, are also susceptible to severe illness and even death from RSV ([WHO](https://www.who.int/news-room/fact-sheets/detail/respiratory-syncytial-virus-(rsv))). RSV infection is common throughout all age groups, but often undetected and underestimated in adults.
New Immunization Options for Protection
The landscape of RSV prevention has changed significantly in recent years. For infants, two types of monoclonal antibody products – clesrovimab and nirsevimab – are available to provide protection against severe RSV disease. These antibodies are administered as a single injection and offer protection for approximately five months, covering the period when infants are most vulnerable ([CDC](https://www.cdc.gov/vaccines/hcp/by-disease/rsv.html)). For children ages 8 through 19 months at increased risk of severe RSV disease entering their second RSV season, only nirsevimab is recommended.
vaccines are now available to protect both pregnant women and older adults from severe RSV illness. Maternal vaccines, administered during pregnancy, help protect newborns by passing antibodies to the baby before birth. For adults aged 60 years and older, RSV vaccines are available to help prevent severe disease, hospitalization, and complications ([WHO](https://www.who.int/news-room/fact-sheets/detail/respiratory-syncytial-virus-(rsv))).
Staying Vigilant: Prevention and Awareness
Beyond vaccination, several steps can be taken to minimize the risk of RSV infection. These include frequent handwashing, covering coughs and sneezes, avoiding close contact with sick individuals, and disinfecting frequently touched surfaces. It’s also important to remember that RSV can circulate simultaneously with other respiratory viruses like COVID-19 and influenza, making comprehensive preventative measures even more critical ([CDPH](https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/Immunization/RSV.aspx)).
RSV infection can range in severity, and older adults may experience a wide range of symptoms. Research indicates a disproportionately high impact of RSV in older individuals ([PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC11193699/)). Staying informed about RSV and taking proactive steps to protect yourself and your loved ones is essential, especially as we head into peak RSV season.
As research continues and public health strategies evolve, staying informed about the latest recommendations and advancements in RSV prevention will be crucial. The availability of new immunization options represents a significant step forward in protecting vulnerable populations from the potentially serious consequences of this common respiratory virus.
