LUES

An old name for syphilis, a sexually transmitted disease (STD) that has been around for centuries and is caused by Treponema pallidum, a microscopic organism called a spirochete, a worm-like spiral-shaped organism that infects by burrowing into the moist mucous membranes of the mouth or genitals. From there, the spirochete produces the classic non-painful ulcer known as a chancre. There are 3 stages of syphilis. The first ("primary") stage is formation of the chancre.. It is highly contagious and can last 1-5 weeks. The disease can be transmitted from any contact with one of the ulcers, which are teeming with spirochetes. If the ulcer is outside the vagina or on the scrotum, the use of condoms may not help preventitransmission of the disease. Likewise, if the ulcer is in the mouth, merely kissing can spread syphilis. Even without treatment, an early infection resolves on its own in most women. However, 25% will proceed to the next stage of the disease called "secondary" syphilis, which lasts 4-6 weeks. This secondary phase can include hair loss, a sore throat, white patches in the nose, mouth, and vagina, fever, headaches, and a skin rash. There can be lesions on the genitals that look like genital warts but are caused by spirochetes rather than the wart virus. These wart-like lesions, as well as the skin rash, are highly contagious. The rash can occur on the palms of the hands and the infection can be transmitted by casual contact. The third stage of the disease involves the brain and heart and is usually no longer contagious. At this point, however, the infection can cause extensive damage to the internal organs, such as the brain, and can lead to death.
