NOTE: This table should be used only for age comparisons. This is because, if age was not specified, cases were prorated according to the distribution of cases for which age was known. For 1997, Delaware did not report age for most chlamydia cases and was excluded from the case counts and the U.S. population denominators. Differences between total cases from this table and others in the report are due to different reporting forms and above listed exclusions. The 0 to 9 year age group is not shown because some of these may not be due to sexual transmission; however, they are included in the totals.
