Chlamydia seems to be on the rise. Working in a hospital lab I've seen an increase in tests for HPV, Herpes and Gonorrhea. It's enough to make one wonder if sex is worth the risk.
Haunted House = No STDs! "As visitors make their way through a dimly lit, S-shaped maze, they view startling, full-color photos of canker sores and genital warts on male and female genitalia infected with syphilis, chlamydia or gonorrhea. An empty casket at the end sends a message that death awaits anyone who does not practice safe sex."
