Since its inception in 1990 the Northern Sydney Public Health Unit (PHU) has used letters to provide information and advice to parents during an outbreak of an infectious disease in a childcare setting. In conjunction with the letter the PHU offers advice on infection control to the centre. Anecdotal evidence from centres, parents and general practitioners has indicated such information is useful and we recently carried out a formal validation of this method of delivering health information.
