Hello, Welcome to HCM, Respiratory syncytial virus (RSV) is a common and highly contagious virus that infects the respiratory tract of most children before the completion of two years of age. In small percentage of children with the RSV virus can lead to serious problems such as bronchiolitis and pneumonia, which can become life-threatening. Most common symptoms of RSV infection are cold-like symptoms including cough and runny nose usually last one to two weeks. There is no medication to treat the virus itself. So management includes treating symptoms of infection and its effects on the respiratory system. Majority of the children can be managed at home by removing sticky nasal fluids using saline drops, using vaporizer to keep the air moist and make breathing easier, providing fluids in small amounts frequently through out the day. Medications like antipyretics will reduce the fever.If the babies are having serious complications requires hospitalization. Thank you.
