    Spiking Early Syphilis in San Francisco
    Figure 1. Just as the CDC launched a 1999 campaign to eradicate syphilis in the United States by focusing on heterosexual African Americans, incidence of this easily transmitted STI surged among San Francisco MSM prowling the Internet to meet sex partners. (Graph from MMWR.19)
    Treponema pallidum
    Figure 2. Treponema pallidum, the bacterium that causes syphilis, has a corkscrew shape that it exploits to prize its way between endothelial cells of a newly exposed person. This photomicrograph shows two bacteria magnified 36,000 times. (From the Centers for Disease Control and Prevention Public Health Image Library [PHIL].)
    Figure 3
    Figure 3. Syphilis proceeds from symptomatic primary and secondary syphilis to the asymptomatic early latent stage and -- if left untreated -- to the late latent stage and ultimately to potentially debilitating and deadly tertiary syphilis. (Adapted from Ho and Lukehart.39)
    Figure 4
    Figure 4. Neurosyphilis and ocular syphilis are not rare in people with HIV and T pallidum coinfection. These manifestations of syphilis often present special challenges in HIV populations. (Illustrations from Servier Medical Art.)
