Data Notes

This indicator is based on sexually transmitted disease data reported to the State Laboratory of Public Health (SLPH). The SLPH provides testing for the Infertility Prevention Project (IPP), which includes testing for chlamydia.  **Durham, Forsyth, Guilford, Mecklenburg and Wake are not included here because they are not funded by the IPP and do not send their screening tests to the SLPH. Percentages are displayed only for counties that have a minimum of 10 positive test results.
