Sexually Transmitted Infections

Alabama’s #6 Health Concern

STIs are infections that can be transmitted through sexual contact with an infected individual. In Alabama, the Division of STI Prevention and Control of the ADPH conducts disease investigations and partner notifications for chlamydia, gonorrhea, human immunodeficiency virus (HIV), syphilis, and trichomoniasis. The long term goals for this division are to reduce the incidence of STIs and their respective sequela, to improve the integration of STI services into clinical care across the health care system, to increase access to STI services for the populations most at-risk, and to reduce the threat of antibiotic-resistent gonorrhea, other emerging STIs, and congenital syphilis.

Alabama STI Highlights

  • Chlamydia, caused by the bacterium chlamydia trachomatis, is the most commonly reported STI in both Alabama and the United States.
  • Alabama has the third highest rate for new chlamydia infections in the United States trailing only Alaska and Louisiana.
  • Gonorrhea, caused by the bacterium Neisseria gonorrhoeae, is the second most commonly reported STI in both Alabama and the United States.
  • Alabama has the second highest rate for new gonorrhea infections in the United States trailing only Louisiana.
  • Syphilis, caused by the bacterium Treponema pallidum, is one of the most commonly reported STI in both Alabama and the United States.
  • Alabama has a lower rate of new cases of primary and secondary syphilis, the most infectious stages of syphilis, than the United States as a whole.
  • There are persons living with HIV in every county in Alabama.
  • The CDC estimates that 18 percent of persons infected with HIV are unaware of their status in 2012. As such, HIV numbers tend to be underestimated.
  • The new HIV case rate for Alabama is slightly lower than the United States.

Health Indicators

Alabamians identified STIs as the sixth greatest current health concern in Alabama. The following indicators have been selected for use in developing a benchmark or starting point for measuring the current state and monitoring future changes with regards to STIs in Alabama:

  • STI Case Rate 2013 | Excel Spreadsheet
  • New HIV Cases Rate, 2010-2012 | Excel Spreadsheet
  • The STI cases rate includes all new infections of chlamydia, gonorrhea, and primary and secondary syphilis but excludes new HIV cases as these cases are represented by their own indicator.
  • These two indicators were chosen because they represent the four most prominent STIs in Alabama.
  • More STI indicators such as individual rates for chlamydia, gonorrhea, and syphilis may be added in the future.
