Respiratory syncytial virus, commonly known as RSV, is a virus that typically causes mild, cold-like symptoms but can lead to more serious respiratory illnesses, particularly in infants and young children. In 2022, there was a notable surge in RSV infections, raising concerns and questions about this common respiratory virus.
RSV is prevalent among young children, with nearly all children having been infected by the age of 2. It can cause repeated infections throughout life but is usually particularly severe in infants and the elderly. RSV is a leading cause of hospitalization in infants, and in 2022, the virus posed a significant health threat, with some cases requiring intensive care. This surge highlighted the importance of understanding RSV, its symptoms, and preventive measures.
The virus is known to cause serious lower respiratory tract infections such as bronchitis and pneumonia due to the secretion it causes in the lungs. It is especially dangerous for young babies, older adults, and individuals with suppressed immune systems or chronic lung or heart diseases.
Symptoms of RSV include fever, runny nose, chest congestion, cough, and in more severe cases, it leads to bronchiolitis and pneumonia. The symptoms tend to be more severe and last longer than those of a typical cold. In infants, the symptoms can include copious amounts of mucus and redness of the eyes.
One of the key aspects of RSV is its mode of transmission. The virus spreads through infected droplets released into the air when an infected person coughs or sneezes. It can also spread through direct contact, like kissing, or through contaminated surfaces.
As we enter another RSV season, there is a ray of hope with the approval of new preventive medications for infants. This development is crucial, given that the U.S. Centers for Disease Control and Prevention estimates that 1% to 2% of infants younger than 6 months who are infected with RSV require hospitalization. RSV is also a concern for high-risk adults and those over 65, as it can cause severe disease.
RSV, which infects the nose, throat, and lungs, is a leading cause of serious lung diseases like pneumonia and bronchiolitis in babies and young children. It’s most common in the fall and winter months.
