Chlamydia rates in the IHS.

This article includes the surveillance data from participating clinics in the "Stop Chlamydia - Use Azithromycin" Program. Because not all clinics within service units are participating in the Azithromycin program, Chlamydia rates by IHS area are greatly underestimated. Of special concern are male partners of infected patients who are often not notified, tested, or treated.
