SYPHILIS


Meaning of SYPHILIS in English

n.

Sexually transmitted disease caused by the spirochete Treponema pallidum .

Without treatment, it may progress through three stages: primary, characterized by a chancre and low fever; secondary (weeks to months later; only half of those infected display symptoms), with a skin and mucous-membrane rash, lymph node swelling, and bone, joint, eye, and nervous system involvement; and tertiary. The tertiary stage follows a latency period that can last years, and only one-fourth of those infected display tertiary symptoms. These can be benign or incapacitating and even fatal; almost any part of the body may be attacked. Syphilis can spread to a fetus from an infected mother. Other species of Treponema cause similar but milder, nonsexually transmitted forms of syphilis (see yaws ). Several blood tests can detect syphilis, even during latency. Antibiotic treatment is effective.
