RSV Vaccine
Respiratory Syncytial Virus (RSV) is a common respiratory virus that can cause mild, cold-like symptoms, but can also lead to severe illness, especially in infants, young children, older adults, and people with weakened immune systems. Vaccines are now available to help protect these vulnerable populations.
Overview
RSV is a highly contagious virus that causes infections of the lungs and respiratory tract. It spreads through respiratory droplets (coughing, sneezing) and close contact. Most children are infected with RSV by the time they are two years old. While infections in healthy individuals usually cause mild symptoms, RSV can lead to bronchiolitis (inflammation of the small airways in the lungs) and pneumonia in infants and young children. In older adults and immunocompromised individuals, RSV can exacerbate existing conditions and cause serious illness.
Risk Areas
RSV is prevalent worldwide. It typically follows a seasonal pattern, with outbreaks occurring more frequently during the fall and winter months in temperate climates. In tropical regions, RSV can circulate year-round. The risk of severe RSV illness is highest for infants, young children, older adults, and people with chronic health conditions, regardless of geographic location.
Risk for Travelers
While RSV is not specifically related to travel, infants, young children, older adults, and immunocompromised individuals who are traveling are still at risk of contracting RSV. If traveling with these vulnerable populations, it's essential to practice good hygiene (handwashing, covering coughs and sneezes) and avoid close contact with people who are sick. Consult with a healthcare provider regarding preventive measures, such as monoclonal antibody injections for infants, especially if traveling during peak RSV season. New RSV vaccines are now available for older adults and pregnant women (to provide passive immunity to their babies). These should be discussed with a doctor before travel.
