In brief: RSV
Respiratory syncytial virus (rsv) causes infection of the respiratory tract.
It starts as a cold, but then the virus spreads to lower respiratory tract and causes infection/inflammation in the smaller breathing tubes (bronchioles): swelling of the lining of the tubes and sloughing of the lining of these tubes with debris building up and causing partial/complete blockage of these tubes.

RSV is one of the more common causes of respiratory viral infection in children and a common reason for hospitalization amongst children less than 2 years of age and in those with complex medical conditions.
Dr. Lois Freisleben-Cook
It is called syncytial because, as Dr. Hasan said, it causes the lining of the airways to shed like a snake sheds it's skin. This produces thick, tenacious material that has to be coughed out. A child under two months old may not have the strength to handle this material.

In brief: Prematurity/immunity
Infants and children born prematurely, with underdeveloped lungs may not have received enough antibodies from their mothers to help them fight off RSV disease once they have been exposed to it.
Boys under 6 months of age,infants and children with chronic lung disease like cystic fibrosis,congenital heart disease, crowded day care centers.

In brief: Bronchiolitis
It is an acute viral infection of the lower respiratory tract of infants below 2years old caused by rsv.
Starts as auri with wheezing, tachypnea, rds with subcostal retraction requiring hospitalization especially with cyanosis for o2 inhal.
