The respiratory microorganism known as baby virus causes a localized infection of the respiratory system, but is generally mild, in certain risk groups, the consequences can be of greater severity. It was thought that children were born prematurely who were more likely to be infected by respiratory syncytial virus (RSV) as they have fewer defenses. However, also the babies with Down syndrome who have not completed 24 months are at increased risk of acute respiratory infection with RSV, compared with children of that age is not affected by the syndrome.
As they were not considered a risk group so far, newborns with Down syndrome did not receive prophylactic treatment are those who hoard the largest number of admissions to hospital with serious breathing problems. This has been shown the CIVIC 21, an epidemiological study of two-year (2006-2008), coordinated by the Spanish Society of Pediatric Cardiology and Congenital Heart Disease (SECPCC) and sponsored by the pharmaceutical industry with the approval of the Ethics Committee Clinical Research of the Hospital Vall d’Hebron, Barcelona.
