A print friendly PDF version is available from this Communicable Diseases Intelligence issue's table of contents.

From this issue onwards an additional set of summary tables presenting data by date of onset for each calendar month, will be included for the National Notifiable Diseases Surveillance System. Data for January 2000, by date of onset, are presented in Tables 1 and 2 of this issue and are discussed in the highlights section. Tables 3 and 4 present data by report date for the 4 week period, 2 to 29   February 2000, for information only.

Tables 1 and 2 include a comparison between the total January 2000 data and the totals for December and January 1999; and a 5 year mean which is calculated using December to February data for the previous 5 years (MMWR Weekly 2000:49;139-146). In subsequent editions year to date figures will also be included and compared to the mean for the year to date figures for the previous 5 years.

Where onset date data were not available the report date has been substituted by the National Centre of Disease Control as a proxy of the onset date.
