Syphilis; any similar disease.
ETYM New Lat., from Syphilus, the name of a shepherd in the Latin poem of Fracastoro, which was published in 1530.
A common venereal disease caused by the Treponema pallidum spirochete; symptoms change through progressive stages; can be congenital (transmitted through the placenta); SYN. syph, pox.
Sexually transmitted disease caused by the spiral-shaped bacterium (spirochete) Treponema pallidum. Untreated, it runs its course in three stages over many years, often starting with a painless hard sore, or chancre, developing within a month on the area of infection (usually the genitals). The second stage, months later, is a rash with arthritis, hepatitis, and/or meningitis. The third stage, years later, leads eventually to paralysis, blindness, insanity, and death. The Wassermann test is a diagnostic blood test for syphilis.
With widespread availability of antibiotics, syphilis is now increasingly cured in the industrialized world, at least to the extent that the final stage of the disease is rare. The risk remains that the disease may go undiagnosed or that it may be transmitted by a pregnant woman to her fetus.
