Gonorrhea, the STI your grandparents knew as the clap is back—and unhappily, it’s stronger than it ever was. A report from the World Health Organization shows that antibiotic resistance is making gonorrhea—the second most reported STI, infecting 820,000 people per year—much harder to treat.

If you’re not scared of getting gonorrhea, here’s a sobering thought—left untreated, gonorrhea can lead to chronic pelvic pain or infertility. Scientists fear that soon, some strains won’t respond to antibiotics at all. The problem is the rampant antibiotic use.

A CDC study found that one third of all antibiotic prescriptions are unnecessary. Doctors prescribe antibiotics for even mild ailments like the common cold.  And the bacteria that causes gonorrhea is resistant to almost every antibiotic.

Things to think about: You should never take an antibiotic unless it is absolutely necessary. You should make sure anyone you decide to have sex with has a medical clearance from all STI’s. Just don’t hop into bed with anyone without them having a medical clearance! AIDs still exists, as does Herpes and Genital Warts. Using a condom helps but is not that reliable.

The CDC is busy tracking resistant infections and developing new ways to target which antibiotic will work best for the specific strain you have.

You have to be wise and cautious!
