It depends on your age…
The US Preventive Services Task Force is the organization that reviews the most cost-effective, efficient treatments. They suggest that all sexually active women, ages 24 or younger, should be screened for both gonorrhea and chlamydia. Women older than 24 should be screened for those two sexually transmitted infections (STIs) if they are at “increased risk.” (Think new partners, multiple partners, or vaginal discharge with itching, burning or odor.)
For men, there is not sufficient evidence to make a recommendation for OR against screening.
Facoid: Did you know that the two most common STIs in America are chlamydial infections with 1.4 million cases in 2012 and gonococcal infections with 330,000 cases in 2012? Half of the cases of STIs are in people aged 15 to 24.
