January 7, 2013  |  Health

People often travel to New York to experience the city’s museums, theaters, nightlife, and world class dining and shopping opportunities. People love traveling to California to enjoy beautiful beaches, fun in the sun, and warm weather. People also travel throughout America looking for personal pleasure of the sexual variety. Is it really a good idea, however, to travel to the South for sex? Let’s explore the regional prevalence of chlamydia, gonorrhea, syphilis, and AIDS in the U.S.

Chlamydia is the most frequently recorded STD in the country—there are 1,307,893 reported cases, according to the Centers for Disease Control and Prevention (CDC). One out of every 15 sexually active females aged 14-19 years has chlamydia. The South has the highest prevalence of Chlamydia cases (469.8 people per 100,000). The top five states for chlamydia are Hawaii, Mississippi, Louisiana, South Carolina, and Alabama. In the most recent study done by the CDC, a total of 309,341 cases of gonorrhea were reported in the U.S. Southern states dominate terms of gonorrhea rates, with the following leading the pack: Mississippi, Louisiana, South Carolina, Alabama, and Arkansas.

The CDC states that there are a total of 13,774 reported cases of syphilis in the country. If left untreated, syphilis can cause long term complications and even death. Again, the South dominates in overall syphilis prevalence, with the following leading the field: Louisiana, Georgia, Mississippi, Arkansas, and Illinois. More than 619,000 people with AIDS in the U.S. have died since the epidemic began in June of 1981. Maryland has the highest prevalence of AIDS in the country—22.1 people per 100,000 have the disease. Also, national estimates suggest there are 7,500 Marylanders who are HIV positive and unaware of their status.
