Syphilis Information
Syphilis is a complex, sexually transmitted disease (STD) with a highly variable clinical course. The disease is caused by the bacterium, Treponema pallidum. In the United States, 36,935 cases of syphilis, including 349 cases of congenital syphilis, were detected by public health officials in 2006. Six of the ten states with the highest rates of syphilis are located in the southern region of the United States.
Syphilis is passed from person-to-person through direct contact with a syphilis sore (called a chancre). Chancres mainly occur on the external genitals, vagina, anus, or rectum, but may also occur on the lips and in the mouth. Transmission of syphilis occurs during vaginal, anal, or oral sex. Pregnant women with the disease can pass it on to their babies.
Syphilis cannot be spread by toilet seats, door knobs, swimming pools, hot tubs, bath tubs, shared clothing, or eating utensils.
The first symptoms of syphilis can appear from 10-90 days (average 21 days). The first stage is marked by the appearance of a chancre that is usually firm, round, small, and painless. The chancre lasts 1-5 weeks and heals on its own. The second stage of syphilis begins when one or more areas of the skin develops a non-itching rash. Rashes can appear as rough, "copper penny" spots on the palms of the hands and bottom of the feet; a prickly heat rash, small blotches or scales all over the body; a bad case of old acne; moist warts in the groin area; white patches in the mouth; sunken dark circles the size of a nickel or dime; or as pus-filled eruptions like chicken pox. Rashes can last 2-6 weeks and, like the chancre, heal on their own. During the first and second stages of syphilis, an infected person can easily pass the disease to their sex partners.
The latent (hidden) stage of syphilis begins when the secondary symptoms disappear. If the infected person has not received treatment, he/she still has syphilis even though there are no symptoms. Syphilis remains in the body and begins to damage the internal organs including the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints.
An infected pregnant woman has about a 40% chance of having a stillbirth (syphilitic stillbirth) or delivering a baby who dies shortly after birth. A baby born to a mother with either untreated syphilis or syphilis treated after the 34th week of pregnancy has a 40%-70% chance of being infected with syphilis (congenital syphilis). The baby may be born without symptoms, but will develop them within a few weeks, if not treated immediately. Some infected babies are born with very serious health problems including skin sores, a very runny nose which is sometimes bloody (and infectious), white patches in the mouth, inflamed arm and leg bones, a swollen liver, anemia, jaundice, or a small head. Untreated babies may become retarded or have seizures. About 12% of infected newborns will die because of the disease.
Bicillin, a type of penicillin (G benzathine), will cure a person who has had syphilis for <1 year. More doses are needed to cure someone who has had it longer. A baby born with the disease needs daily penicillin treatment for 10 days. There are no home remedies or over-the-counter drugs that cure syphilis. Washing the genitals, urinating, or douching after sex does not prevent syphilis. Any unusual discharge, sore, or rash -especially in the groin area - should be a signal to stop having sex and to see a doctor immediately.
