For many parents, respiratory syncytial virus – or RSV – which has been causing record numbers of hospitalizations of children during the fall of 2022, may sound like a relatively new and unheard-of threat. But in fact, RSV is a common respiratory virus that circulates every fall and winter and is a common cause of lung infections in young children.
RSV can be difficult to distinguish from other respiratory infections since the symptoms are common to other illnesses – runny nose, sneezing, congestion, coughing, fever, decreased appetite and wheezing. In most cases, RSV is mild and will improve at home. However, in certain cases, it can cause severe illness and require hospital treatment.
