my little sister had RSV after she was born, everything should be okay mama don't worry too much.

respiratory virus that infects the lungs and breathing passages. Healthy people usually experience mild, cold-like symptoms and recover in a week or two. But RSV can be serious, especially for infants and older adults. In fact, RSV 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. @mybabyboytimmy020516
