From the SacBee:

Almost 40 percent of Sacramento County's teens and young adults carry a sexually transmitted disease, the third-highest rate in the state, according to a study from the Public Health Institute released Tuesday.

The study included STD estimates among 15- to 24-year-olds for several diseases that are not reported because labs or doctors are not required to notify the county or state when they are detected. […]

Last month, a Bee article noted sharp increases in Sacramento's reportable STDs — diseases such as chlamydia and gonorrhea.

The chlamydia rate rose 52 percent from 2002 through 2006; the gonorrhea rate jumped 35 percent. […]

But Trochet said Sacramento County's high rate is largely attributable to a lack of resources to combat the diseases. Also, she said, the larger the pool of STD carriers, the faster the disease spreads.

C'mon, kids.  Listen to Van Wilder: Don't be a fool – wrap your tool.
