Human parainfluenza virus-associated hospitalizations among children less than five years of age in the United States.
Human parainfluenza viruses 1 through 3 (HPIV-1-3) are important causes of respiratory tract infections in young children. This study sought to provide current estimates of HPIV-1-3-associated hospitalizations among US children. ⋯ We provide broad, serotype-specific estimates of US childhood hospitalizations associated with HPIV infections. More precise estimates of HPIV-associated hospitalizations would require large prospective studies of HPIV-associated diseases by more sensitive viral testing methods, such as polymerase chain reaction techniques.
