In this review, we describe the history, epidemiology and clinical manifestations of infections attributed to respiratory syncytial virus (RSV) in children. At present, no cure exists for RSV infection but commonly employed palliative treatments include oxygen and inhaled beta(2)-adrenoceptor agonists, such as salbutamol, to relieve the wheezing and increased bronchiolar smooth muscle constriction. Adrenaline (epinephrine) has been found to be superior to the selective beta(2)-adrenoceptor agonists. Oral or inhaled corticosteroids should counteract the inflammatory response to RSV infection but their effectiveness is controversial. Inhaled ribavirin is the only licensed antiviral product approved for the treatment of RSV lower respiratory-tract infection in hospitalized children, although its use is now restricted to high-risk infants. Other treatments considered are nasopharyngeal suctioning, surfactant therapy, recombinant human deoxyribonuclease I, heliox (helium:oxygen) and inhaled nitric oxide. Prevention of infection by RSV antibodies is another strategy and, currently, palivizumab is the only safe, effective and convenient preventative treatment for RSV disease in high-risk populations of infants and young children. Its cost-effectiveness, however, has been questioned. Both live attenuated and subunit vaccines against RSV infection have been developed but so far there is no safe and effective vaccine available. Finding effective treatments and prophylactic measures remains a major challenge for the future.

Acute bronchiolitis (AB) is a frequent cause of hospitalization among children and its main etiological agent is respiratory syncytial virus (RSV). It occurs epidemically during autumn and winter. Some populations of children such as premature newborns, infants with congenital heart disease and those with chronic lung disease, immunocompromised, undernourished, among others, present increased morbidity and mortality risk. The virus multiplies in epithelial ciliated cells while inflammation and cellular debris cause obstruction of the airways, hyperinflation, atelectasis, and wheezing and gas exchange imbalance. Definitive evidence still does not exist about treatment of this disease, Treatment includes oxygen therapy, hydration, inhaled beta-2 agonists, racemic epinephrine, recombinant DNase and respirotherapy, among others. Prophylactic measures include administration of monoclonal antibodies. The majority of children with AB, independent of disease severity, recover without sequels. The natural course of this disease usually varies, from seven to ten days ,however some children may not recover for weeks.
