Incidence patterns of respiratory illness in Queensland estimated from sentinel general practice.
Incidence rates of six respiratory infections were calculated from sentinel practice data of 33,407 reports coming from 31 general practitioners in Queensland over 34 months in 1986/1988. Upper respiratory tract infection had an annual incidence of 301 per 1000 people, most in children aged under five, and a winter rate twice the summer rate. Sore throat (incidence 112:1000) and Infectious mononucleosis (incidence 2.7:1000) had little seasonal variation and were maximal among those aged 15-19 (in whom there was one case of Infectious mononucleosis for every 14 sore throats). Influenza (incidence 44:1000) underwent a prominent epidemic in the winter of 1988. Measles (incidence 1.9:1000), and pertussis and pertussis-like syndrome (incidence 0.8:1000) were most commonly reported in the under-fives, and rarely among adults. Sentinel practices networks collect useful epidemiological data from which disease incidences can be calculated.
