Sexually Transmitted Diseases (STDs)

Also referred to as Sexually Transmitted Infections (STI), STDs are illnesses that have a significant probability of transmission between humans by means of human sexual behavior, including vaginal intercourse, oral sex, and anal sex.

Below are some common examples:

Gonorrhea

Symptoms of gonorrhea usually appear 2 - 5 days after infection, however, in men, symptoms may take up to a month to appear. Some people do not have symptoms. They may be completely unaware that they have caught the infection, and therefore do not seek treatment. This increases the risk of complications and the chances of passing the infection on to another person.

Symptoms in men include:

Burning and pain while urinating
Increased urinary frequency or urgency
Discharge from the penis (white, yellow, or green in color)
Red or swollen opening of penis (urethra)
Tender or swollen testicles
Sore throat (gonococcal pharyngitis)

Symptoms in women can be very mild or nonspecific, and may be mistaken for another type of infection. They include:

Vaginal discharge
Burning and pain while urinating
Increased urination
Sore throat
Painful sexual intercourse
Severe pain in lower abdomen (if the infection spreads to the fallopian tubes and stomach area)
Fever (if the infection spreads to the fallopian tubes and stomach area)
If the infection spreads to the bloodstream, fever, rash, and arthritis-like symptoms may occur.

Syphilis

Symptoms of primary syphilis are:

Small, painless open sore or ulcer (called a chancre) on the genitals, mouth, skin, or rectum that heals by itself in 3 - 6 weeks
Enlarged lymph nodes in the area of the sore
The bacteria continue to grow in the body, but there are few symptoms until the second stage.

Secondary syphilis symptoms may include:

Skin rash, usually on the palms of the hands and soles of the feet
Sores called mucous patches in or around the mouth, vagina, or penis
Moist, warty patches (called condylomata lata) in the genitals or skin folds
Fever
General ill feeling
Loss of appetite
Muscle aches
Joint pain
Swollen lymph nodes
Vision changes
Hair loss

Symptoms of tertiary syphilis depend on which organs have been affected. They vary widely and are difficult to diagnose. Symptoms include:

Damage to the heart, causing aneurysms or valve disease
Central nervous system disorders (neurosyphilis)
Tumors of skin, bones, or liver

AIDS

AIDS begins with HIV infection. People who are infected with HIV may have no symptoms for 10 years or longer, but they can still transmit the infection to others during this symptom-free period. If the infection is not detected and treated, the immune system gradually weakens and AIDS develops.

Acute HIV infection progresses over time (usually a few weeks to months) to asymptomatic HIV infection (no symptoms) and then to early symptomatic HIV infection. Later, it progresses to AIDS (advanced HIV infection with CD4 T-cell count below 200 cells/mm3 ).

Almost all people infected with HIV, if they are not treated, will develop AIDS. There is a small group of patients who develop AIDS very slowly, or never at all. These patients are called nonprogressors, and many seem to have a genetic difference that prevents the virus from significantly damaging their immune system.

The symptoms of AIDS are mainly the result of infections that do not normally develop in people with a healthy immune system. These are called opportunistic infections.

People with AIDS have had their immune system damaged by HIV and are very susceptible to these opportunistic infections. Common symptoms are:

Chills
Fever
Rash
Sweats (particularly at night)
Swollen lymph glands
Weakness
Weight loss

At first, infection with HIV may produce no symptoms. Some people, however, do experience flu-like symptoms with fever, rash, sore throat, and swollen lymph nodes, usually 2 - 4 weeks after contracting the virus. This is called the acute retroviral syndrome. Some people with HIV infection stay symptom-free for years between the time when they are exposed to the virus and when they develop AIDS.
