Few Infectious Diseases are transmitted after 100% of exposures. In the case of chlamydia, estimates are that there's a 40-50% chance of getting it from any episode of vaginal sex with an infected partner. This can do with various factors. For instance, the presence of another infectious disease (like herpes) can be a "window of opportunity" for a second infectious disease to enter. Our bodies, and the "shedding" schedule of a present virus or disease have a lot to do with it too. Basically, just luck.
Also, it could be a false-positive or false-negative result.
It's possible that an intervening antibiotic prescription for some other purpose, such as amoxicillin for sinusitis or doxycycline for Lyme disease, could have cleared the infection in one person before they even knew they had it.
In addition, a certain percentage of people clear chlamydia without treatment. The infection may still have done damage before the immune system cleared it.
A few people may have a temporary mild immunity to chlamydia after recent infection, so it's possible that one person just had a little more immune protection against the infection than the other.
The important points to remember:
You can get chlamydia from someone who is infected. The partner's cleanliness has nothing to do with it.
The requirements for partner tracing for chlamydia vary from one county to another. You can contact your county health department to inquire about their practices.
One myth about chlamydia is that you would know if you had it. Most diagnosed patients had no symptoms. Another myth is that you have to sleep around to get it. One partner is plenty.
Chlamydia is spread by oral, anal, and vaginal sex; genital-genital contact; sharing sex toys; and birth to an infected woman. Even if you and your partner haven't had sex before, you could have been infected with chlamydia from one of these other activities.
It is nearly impossible to get chlamydia without direct sexual contact. The only object that might spread it is a sex toy, if you're sharing while having sex with an infected partner. Chlamydia can only survive outside the body for a few minutes.
No, you can not catch chlamydia from someone that is not infected. You can only get chlamydia by having intimate contact with someone who has chlamydia. If you and your partner don't have it, you can't catch it from each other.
No she can not.
Well......yea! Unfortunately not everyone is faithful. My friend got it from her own husband. She had no symptoms at all, they found it during a routine exam. Not to mention, whos to say he or she has only been with one person. Please don't be silly. Chlamydia is easily treated, AIDS is not!
Yes, this is possible.
Yes, you can still love a partner even if you think he gave you chlamydia. In a new relationship, it's not unusual for one partner to have chlamydia without knowing, and to transmit it to a partner. On the other hand, if you think he may be unfaithful and putting you at risk for STDs without your knowledge, you'll have to consider your own health and safety from continuing to have sexual contact with him.
Typical treatment in pregnancy is one gram of azithromycin -- the same treatment for non-pregnant people with chlamydia. In many states, the partner can be treated without an exam, but laws vary from state to state. Ask your OBGYN about the possibility in your area.
Chlamydia will likely recur in exposed to the bacteria again. Among teen females, one in four to one in five will have chlamydia again within two years of treatment. It is critical that all patients get retested for chlamydia three months after treatment. Annual testing and testing with a new partner are also important.
