Osmosis video - Respiratory syncytial virus

Respiratory syncytial virus (RSV) is most known to infect the human respiratory tract and cause bronchiolitis, which is an inflammation of the bronchioles, the smallest air passages of the lungs. It usually occurs in children less than two years of age with the majority being aged between three and six months. It presents with coughing, wheezing, and shortness of breath which can cause some children difficulty in feeding. Bronchiolitis is typically diagnosed clinically, and the treatment is supportive with supplemental oxygen and giving fluids to prevent dehydration.
