Abstract:
In a community-based birth cohort of 158 Australian infants followed to age 2 years, the incidence rate of human parainfluenza virus (HPIV) was 0.42 (95% CI = 0.33, 0.54) episodes per child-year with episodes occurring year-round, peaking in the spring season. HPIV-3 was the dominant subtype. Overall, 41% of detections were asymptomatic; only 32% of HPIV episodes led to healthcare contact with 1 hospitalization.
