^*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.

^†New York City has been reporting chlamydia cases since 1984. The State of New York, with the exception of New York City, initiated chlamydia reporting during the year 2000. The number of chlamydia cases reported in 2000 by the state of New York may be incomplete and the rate for New York State is underestimated. See Appendix (Chlamydia Morbidity Reporting).

^§Includes cases reported by Washington, D.C., and rates exclude population of states that did not report.
