*The number of chlamydia cases occurring in the fourth quarter of 2000 for the State of Colorado was projected based on case counts from the first three quarters.

The number of chlamydia cases reported from 1998-2000 by the state of New York may be incomplete and the rate for New York State is underestimated. See Appendix (Reporting of Chlamydia Cases).
