FIG. 1.

Sexual network components including recent contacts with nonconcordant gonococcal genotypes. Panels A, B, and C show data for three network components. Circles (females) or squares (males) represent identified sexual contacts. Where an isolate was available, the information within the circle or square shows the patient number, the date of the clinic visit, and the ST. Additional contacts that are not in a circle or square were reported but unidentified. Each arrow indicates that an individual identified the other as a contact. Two arrows between individuals denotes mutual naming. The period between the visits of the contacts to the clinic are indicated.
