Sex infections still rising, especially in teens

Sex infections still rising, especially in teens. Better screening cited for some increase in STDs, new CDC report finds. Sexually spread diseases continue to rise, with reported chlamydia cases setting yet another record in 2008, government health officials said Monday.

Last year there were 1.2 million new cases of chlamydia, a sometimes symptomless infection that can lead to infertility in women. It was the most ever reported, up from the old record of 1.1 million cases in 2007.

Better screening is the most likely reason, said Dr. John M. Douglas Jr. of the U.S. Centers for Disease Control and Prevention.

Syphilis, on the verge of being eliminated in the United States about 10 years ago, also has been increasing lately. About 13,500 cases of the most contagious form of the disease were reported in 2008, up from about 11,500 the year before.

Unlike chlamydia, health officials think syphilis cases actually are increasing. Syphilis rates are up among both gay men and heterosexuals, said Douglas, director of the CDC's Division of STD Prevention.

Syphilis can kill if untreated, but chlamydia is not life-threatening. Neither is gonorrhea, which seams to have plateaued in recent years. Gonorrhea cases dropped to about 337,000 cases in 2008, down from about 356,000 cases.

Girls, ages 15 through 19, had the largest reported number of chlamydia and gonorrhea cases, accounting for more than one in four of those cases. But they're often screened more than other people, since 1993 federal recommendations that emphasize testing for sexually active women age 25 and under.

Talking about sex


Squeamishness about talking about sex has helped keep common sexually transmitted infections far too common, researchers indicated.

The administration of President Barack Obama has signaled a willingness to move away from so-called abstinence-only sex education approaches promoted by his predecessor, George W. Bush, and conservative state and local governments.

Several studies have shown such approaches do not work well and that it is better to encourage abstinence while also offering children and teens information about how to protect themselves from diseases as well as pregnancy.

"We haven't been promoting the full battery of messages," Douglas said. "We have been sending people out with one seatbelt in the whole car."

The government estimates there are roughly 19 million new cases of sexually transmitted disease annually. Experts say the most common is HPV, human papillomavirus, which can cause genital warts, cervical cancer and other cancers.

The government doesn't ask doctors to report every HPV case, but estimates the virus causes 6.2 million new cases each year. That is an old estimate, based on data from 2000, before a vaccine against some types of HPV came on the market in 2006.

The CDC's latest study on STDs found:

  • Nearly 337,000 cases of gonorrhea were reported.
  • Adolescent girls 15 to 19 years had the most chlamydia and gonorrhea cases of any age group at 409,531.
  • Blacks, who represent 12 percent of the U.S. population, accounted for about 71 percent of reported gonorrhea cases and almost half of all chlamydia and syphilis cases in 2008.
  • Black women 15 to 19 had the highest rates of chlamydia and gonorrhea.
  • 13,500 syphilis cases were reported in 2008, an almost 18 percent increase from 2007.
  • 63 percent of syphilis cases were among men who have sex with men.
  • Syphilis rates among women increased 36 percent from 2007 to 2008.
  • The government estimates 56,000 new cases of HIV each year.

There are 1.6 million new cases of genital herpes each year, but that is also an old estimate for a non-reportable disease.

Syphilis, chlamydia and gonorrhea can all be treated with antibiotics but untreated can cause pelvic inflammatory disease, infertility, ectopic pregnancy and can infect newborns.

Overall, CDC estimates that 19 million new sexually transmitted infections occur each year, almost half among 15- to 24-year-olds. ( msn.com )
