respiratory syncytial virus

 Respiratory syncytial virus (RSV) is a very common virus that infects the respiratory tract and is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children younger than 1 year of age.

Some key facts about RSV:

It is a seasonal virus, with most cases occurring in the fall, winter, and spring. Babies and young children are at highest risk.

Common symptoms include runny nose, decrease in appetite, cough, wheezing, and fever. Symptoms are usually mild but can sometimes require hospitalization.

It spreads through contact with respiratory secretions from infected individuals, such as when coughing or touching contaminated surfaces.

Diagnosis is based on symptoms and can be confirmed by respiratory virus testing ( PCR or immunoassay). Chest x-ray may show lung infection.

Treatment is supportive care with nasal suctioning and fluids. Supplemental oxygen, breathing treatments, and ventilator support may be needed for severe cases.

There is no vaccine yet but some high-risk infants can receive monthly injections of palivizumab (Synagis) during RSV season to help prevent severe disease.

Good handwashing, avoiding contact with sick children, and disinfecting surfaces can help prevent spread.

RSV is very common in babies and young kids but vaccination efforts aim to better prevent its most serious consequences.
