Cause: An unusual bacterium called Chlamydia trachomatis. It is unusual, as bacteria go, because it is a very small parasite that lives inside the cells that it infects. It also has an unusual life cycle.

Incubation Period: In men, symptoms of infection begin to show within one to two weeks after exposure to someone who is infected.

Transmission: Chlamydia is fairly easy to get and to give to someone.

It happens by intimate genital contact, through insertive or receptive vaginal sex. Also, intimate skin contact such as dry humping, and any genital-to-genital contact, even without penetration, can transmit the Chlamydia organism.

Secondary contact can transmit the disease as well. For example, fondling, foreplay, and petting will all transmit Chlamydia. It's best to ask your partner if they currently have a Chlamydia infection. Sometimes, however, Chlamydia can infect you without making you sick -- a person can have it and look totally healthy. Secondary contact is how some people autoinoculate themselves--that is, they spread it to other parts of their body just by touching an infected area and then touching their eye. Chlamydia will then infect the eye. In some countries (but not the United States), there are so many people infected that flies can transmit the disease by landing on an infected person's eye and then spreading the organism to uninfected hosts.

A very big problem is the transmission of Chlamydia to a baby during birth. There is a 60% to 70% chance that this will happen, if an infected mother gives birth.

What to Look For: Chlamydia can grow in the male and female urethra, as well as the eye. In women, it can also grow deep inside the pelvis. These are the only locations where it grows.

In both men and women, the symptoms of a Chlamydia infection can range from no visible signs to a small, clear discharge from the urethra. Redness and irritation of the affected area is common. Without signs of an infection, it is easy to not be careful and to pass the disease on to other people. In the eye, Chlamyda can cause redness and irritation. In the worst cases, it can cause a strong reaction where the lining of the eye becomes hugely swollen and red, as in the picture above. An infection lasts for months to years if not treated.

Treatment: Chlamydia is easily treated with various antibiotics. Some people who have had a LOT of Chlamydia infections don't ever get it again. There is no latency with Chlamydia, so a person who is cured doesn't have to worry about the infection coming back. That is, unless you get it again, of course.

However, after an infection, the area of the urethra or eye that was infected can become scarred, producing some long-lasting irritation.

Contact your health provider as soon as you think you may have gotten an STD; the sooner you are treated, the better your chances of recovery, and it is less likely you will get complications. Also, have your partners checked out, and stop having sex until you get better. Otherwise, you and your partners could keep passing the disease back and forth to each other.

Complications: In women, Chlamydia can have very serious consequences. It can cause a deadly, painful infection called Pelvic Inflammatory Disease (PID). PID can cause sterility so that a woman can never become pregnant, or it can cause very complicated pregnancies. It is VERY important to get examined often if you are sexually active.

Having a chlamydia infection makes it easier for secondary or opportunistic infections to happen. This is especially true for HIV, which can easily get into your body if your urethra is irritated. Also, if you have HIV and chlamydia, then you are more likely to transmit HIV to another person.

Important to note for the mongering community in TJ:

Even prostitutes with valid health cards are not screened for chlamydia. It is not one of the STD's that has mandated screening for sex workers. It is also notable that about two-thirds to three-quarters of women infected with chlamydia will not notice any symptoms. There may be some noticeable signs. . .if the chica allows you to perform a speculum exam and you examine a saline wet mount prior to sex (carrying that microscope through the zona in a back pack will get tiring); then again there may not be.

An intact condom used properly every time you have intercourse will go far in protecting you against infection with chlamydia.

Sex workers are not examined for herpes simplex virus or human papilloma virus infection either.

They do get tested for gonorrhea and syphilis monthly and HIV every three months. That is, if they maintain a valid health card.

MY Kaiser doctor told me I shouldn't worry about it for me, and for my girlfriend only if she was still of childbearing age. But this is BAD medicine. I consider myself a "Kaiser Victim".

San Diego county STD testing clinic counselor - upon direct questioning told me that - short of open sore contact - It can't reproduce in the mouth, hence; I can't get or give it while receiving ablow job or doing DATY, just during genital/genital sex.

Viva la Doxycycline!! I is all better now.

What the San Diego County STD clinic gave me was one dose (and one dose only !)of 1 gram (1,000 mg) of Zitromax in liquid suspension and an admonition not to engage in unprotected sex for one week.

The biggest pharmacy between 2nd & 3rd on the west side of Revolucion has 6 pills of 250 mg each (generic zitromax) for about $19.00. (Use four for 1,000 mg)

But the San Diego County STD clinic checks you for multiple STDs for $15.00 and includes free treatment (if needed) and all the condoms you can carry.

Zitromax is better but it was SD County who gave me the Doxycycline, no doubt because it is cheaper. Less convienent but it did the trick. I agrees, San Diego County STD clinic is good folks.
