Respiratory Syncytial Virus (RSV) is a common illness that affects the nose, throat, and lungs. While many people recover with mild symptoms, RSV can be dangerous for infants, older adults, and those with certain health conditions. It’s the leading cause of infant hospitalization and contributes to 6,000–10,000 deaths among older adults annually.
RSV Symptoms and Transmission
RSV spreads through droplets when an infected person coughs or sneezes. It can survive on surfaces for hours, making hand hygiene and surface cleaning essential. Common symptoms include runny nose, coughing and sneezing, fever, and wheezing or difficulty breathing.
Why RSV Is Dangerous for Infants
RSV is the leading cause of hospitalization for infants. Watch for signs like trouble breathing, poor feeding, and unusual sleepiness or irritability. Review this RSV fact sheet from Public Health – Seattle & King County for more information on RSV and children.
Risks for Older Adults
Older adults, especially those with chronic conditions, may experience more severe symptoms. RSV can worsen existing heart or lung issues and lead to complications like pneumonia.
Who Should Get the RSV Vaccine?
RSV immunizations are available for people most at risk for severe disease. Here’s who should consider getting vaccinated:
- Adults 75 and older: If you’ve already gotten an RSV vaccine, you do not need to get another one at this time.
- Adults 50–74 with high-risk conditions: This includes chronic heart or lung disease, diabetes, or other conditions that weaken the immune system.
- Pregnant individuals: Vaccination is recommended between 32–36 weeks of pregnancy, ideally between September and January, to protect newborns during peak RSV season.
- Babies younger than 8 months: If their birth mother wasn’t vaccinated during pregnancy, infants may be eligible for monoclonal antibody protection. Note, while this is not a vaccine, it does offer at least five months of protection. A dose of RSV vaccine is also recommended for some children ages 8-19 months with high risk conditions who are entering their second RSV season.
Talk to your healthcare provider or pharmacist about getting the RSV immunization for yourself or antibody protection for your infant.
