Respiratory Syncytial Virus (RSV)

Respiratory Syncytial Virus (RSV) is a contagious virus that causes respiratory infections, especially in infants and young children. It’s most active during late fall and winter, leading to symptoms like runny nose, sneezing, fever, and cough. This page provides information about RSV, its diagnosis, treatment, and preventive measures.

Understanding RSV

RSV is a highly contagious virus that primarily affects the respiratory system. It can lead to severe respiratory illnesses such as bronchiolitis and pneumonia, especially in infants, young children, and those with weakened immune systems.

Diagnosing and Treating RSV

RSV is diagnosed based on symptoms and a physical exam, although a healthcare provider may sometimes order a swab test to confirm the presence of the virus. Unfortunately, there is no specific treatment for RSV, but there are steps you can take to relieve symptoms, including using over-the-counter medications and staying hydrated.

Causes and Symptoms of RSV

RSV is primarily spread through contact with respiratory secretions or contaminated surfaces. Once infected, it can cause inflammation and mucus production in the airways, leading to symptoms like runny nose, sneezing, fever, cough, and wheezing. Infants and young children are particularly susceptible due to their smaller airways.

When to Be Concerned About RSV

It’s crucial to consider RSV, especially for children under 5 years old, during late fall and winter when the virus is most active. Prompt medical evaluation is essential for children with respiratory issues, as they may be at risk of complications. Visiting a healthcare provider can help identify those at greater risk and provide guidance on monitoring and care.
