What is RSV

By the way RSV is a common respiratoy virus that most children get by age three. It usually shows up as a mild cold but it can be very serious in preemies.

"Respiratory syncytial virus (RSV) is a virus that causes a lung infection called bronchiolitis. Babies commonly get RSV. Two out of three infants are infected with RSV during their first year of life. RSV is highly contagious. It is spread by contact with infected fluids from the nose or mouth and through droplets in the air from coughing. RSV usually occurs in the wintertime.

Some children with RSV may have pneumonia or they need oxygen. Children born prematurely or who get RSV during the first months of life are more likely to have these complications.

Toddlers and older children with RSV usually do not have serious problems. For these children, RSV is usually no worse than a bad cold."

"Synagis is a medicine that helps prevent serious lung infections caused by RSV. Synagis is an antibody that is made using DNA technology." http://www.med.umich.edu/1libr/pa/pa_rsvsynag_hhg.htm
