The CDC estimates that there are 20 million new sexually transmitted disease (STD) diagnoses each year, which presents not only a massive public health challenge, but $16 billion in direct costs to the healthcare system.
Patients can present with multiple concurrent STDs. Avoid premature diagnostic closure and consider multiple simultaneous processes.
Urinary tract infections and STDs can present similarly. Be sure to do a pelvic examination to avoid misdiagnosis.
Chlamydia is the most common bacterial STD. The diagnostic test of choice is nucleic acid amplification testing (NAAT). Treat with azithro-mycin or doxycycline. See Table 3 for dosages.
