RSV is one of the most common lower respiratory tract illnesses. It is usually confined to children under the age of two. Symptoms are similar to those of the common cold and include coughing, runny nose, fever, wheezing, rapid breathing and skin retractions around the chest and neck. RSV can spread to the airways in the lungs and cause bronchiolitis. Fortunately, most cases are short lived, lasting only a few days. Treat it with home remedies as you would a cold.
