In addition, the lymph glands swell. The virus can remain dormant for even decades, but eventually attack the immune system. AIDS results when the immune system is completely overwhelmed. Death results from problems with the immune system or AIDS-related complications. Dementia is one of these symptoms. Syphilis: This is a bacterial disease that affects men more than it does women (by about 60%). It is cases by the bacterial Terponoma pallidum. It is treatable by penicillin (except in cases of those with allergies, who are treated by other antibiotics). The cure is simple, though several cases go unreported. The symptoms occur in three stages and can even culminate in death. The progress through the stages takes place if the disease is left untreated. The first stage involves painless sores on the genitals, lips and tongues. In the second stage, a brown rash appears on the bottom of the feet and palms. Fever, swollen glands and hair loss occur at this stage. In the last stage the suffering increases from heart ailments, progressive loss of vision, dementia, and also difficulty in moving due to increasing numbness of the extremities.

Syphilis can be transmitted through sexual contact and also unisexual contact through open sores or wounds of an infected person. Transmission can also take place in the womb.

Trichomoniasis: is a parasitic infection. This parasite resides in the vagina for women and the urethra of men. Sexual contact between males-females and female-female results in this disease. Using infected towels or bathing suits might also result in an infection. Women generally show the infection in the form of a discharge, swollen labia, painful intercourse or urination, and genital itching. Men typically don't show symptoms. But might on occasion, suffer from painful urination or ejaculation or penile irritation. In men, in left untreated, it results in problems with the prostate and...

In women, the complications affect the fallopian tubes and the tissues of the cervix. The drug metronidazole has been found to be very useful in treatment of trichomoniasis and can be even given to pregnant women to prevent passing it on to the fetus.
Gonorrhea: Is transmitted by the bacterium Neisseria gonorrheae.

The infection is through exchange of vaginal and seminal fluids through intercourse. In men, the symptoms manifest in pus from the penis, pain while urinating as well as swelling in the testicles. In women, the infection starts from the cervix, travel to the uterus and the fallopian tubes. In case of anal infection, painful bowel movements can occur. The symptoms are fever, vaginal discharge, bleeding at times other than menstruations, nausea and vomiting. An antibiotic treatment immediately cures the condition. If left untreated, there is the risk of infertility in men and women, and a risk in women for ectopic pregnancy. The risks to the fetus are many. Infants from infected mothers are born with possible blindness, arthritis, meningitis and pneumonia. There is a risk of premature birth and miscarriages.

Chlamydia: is a bacterial infection from chlamydia trachomatis. These bacteria live in the vaginal and seminal fluids. The infection can be passed on through vaginal and oral sex and also if there is contact between the hand if the virus resides on it and the eyes. Symptoms often do not arise. If they do, they are vaginal or penile discharge and painful urination. In women abdominal pain may occur; fever and pain during intercourse are also common. For men, occasionally, pain and swelling of the testicles occur. Doxycycline and Azithromycin are used to treat both Chlamydia and Gonorrhea. The complications for men and women and the risks that infected pregnant mothers carry are also very similar. Additionally, with Chlamydia, eye and throat infections can also occur.
