Equal virulence of rhinovirus and respiratory syncytial virus in infants hospitalized for lower respiratory tract infection

Pediatr Infect Dis J. 2012 Jan;31(1):84-6. doi: 10.1097/INF.0b013e31823345bf.


Respiratory syncytial virus (RSV) and rhinovirus (RV) are predominant viruses associated with lower respiratory tract infection in infants. We compared the symptoms of lower respiratory tract infection caused by RSV and RV in hospitalized infants. RV showed the same symptoms as RSV, so on clinical grounds, no difference can be made between these pathogens. No relation between polymerase chain reaction cycle threshold value and length of hospital stay was found.
