Sexually transmitted infections (STIs) are an important public health challenge in the United States. Primary care clinicians can contribute to decreasing these largely preventable causes of morbidity and mortality by integrating routine screening, testing, counseling, treatment, and partner management of STIs into their practice. Newer tests for chlamydia and gonorrhea that can be performed on urine specimens allow screening without a pelvic examination. The most recent edition of the Centers for Disease Control and Prevention sexually transmitted disease treatment guidelines provides an evidence-based, reliable, and convenient set of recommendations for treating and caring for patients who have STIs.
