[Respiratory viruses in pediatrics: what's new?].

Molecular diagnostic tests have greatly increased our knowledge regarding the contribution of respiratory viruses in respiratory illnesses in children, mainly lower respiratory tract infections. Respiratory syncytial virus, rhinovirus (RV) and human metapneumovirus (hMPV) are predominant viral agents identified in children. Notwithstanding the importance of respiratory viruses in children, treatment and prophylactic options remain limited. These include palivizumab, a monoclonal antibody prophylactically administred to high risk children against RSV, vaccines and antivirals such as oseltamivir targeting influenza viruses.
