NOTE: This table should be used only for age comparisons. If age was not specified, cases were prorated according to the distribution of cases for which age was known. Differences between total cases from this table and others in the report are due to different reporting formats. The 0 to 9 year age group is not shown because some of these cases may not be due to sexual transmission; however, they are included in the totals.
