Selected National Notifiable Diseases Surveillance System reports, and historical data 1 1. The historical data are the averages of the number of notifications in the corresponding 4 week periods of the last 3 years and the 2 week periods immediately preceding and following those. Notifications of diseases received by State and Territory health authorities in the period 11 November to 8 December 1998. Diseases preventable by routine childhood immunisation are presented in Table 2. 2. For HIV and AIDS, see Tables 6 and 7.
Totals comprise data from all States and Territories.
Cumulative figures are subject to retrospective revision so there may be discrepancies between the number of new notifications and the increment in the cumulative figure from the previous period. Data from Victoria for 1998 are incomplete. Not reported for NSW because it is only notifiable as 'foodborne disease' or 'gastroenteritis in an institution'. Qld and Vic incident cases of Hepatitis C are not separately reported. Nationally reportable from August 1998.
