Can chlamydia go unnoticed for five years?

Yes, it most certainly can and does. Chalmydia is known as a silent infection because it often causes no symptoms at all in the majority of women until they seek care for the complications it causes. If there are any symptoms at all in women, they occur within a few weeks of being infected, and are easily missed or misdiagnosed. Men are far more likely to have symtoms, with a whitish discharge from the penis happening within a few days of exposure. This is often missed as well, and a good many men have no idea they have the infection.
Most women find out they have the infection when they go see the doctor for another gyn problem, and the doctor does a smear test specifically for it. It is nearly impossible to tell when the infection actually occured, or even how long ago it happened. It's impossible to even tell which partner infected which. Husbands can give it to wives, wives can give it to husbands- you never know which. That's why both partners get treated, along with any other partners you name. The naming part is very sensitive, and a doctor will not discuss the matter with the two of you together. Neither will they tell you if the other person named anyone else. In many cases, you can have a couple who has been together, faithful and monogamous, for years, and there is no one else to name because they just don't know or remember. Either partner could have brought the infection to the relationship unknowingly. There is nothing to be gained by finger pointing, as there is no way to know who is responsible.
So, it doesn't mean either partner has been unfaithful. All it means is you have an infection which needs to be treated. Don't get hung up on who did what and when. Nothing in your relationship has to change, and there's no need to let this be a point for arguement or blame. You wouldn't get excited if it were a yeast infection, or any other kind of infection, so don't get excited over this. Source(s): Nurse

that's what i told my wife
If u don't go and get regular exams, yes. Many ppl don't show symptoms of chlamydia.
Yes. It can be symptomless, especially in males. But it can cause a lot of damage in both sexes, so it's allways better to get things checked out. The test is very simple, and treatment consists of a course of antibiotics. It's one of a range of sexually transmitted diseases which are becoming increasingly widespread. I's probably best to get checked for everything if you're worried, as often these nasty bugs coexist.

And remenber, it's never too late to practise safer sex.
yes you can have it and theres A chance you have no symptoms at all and you wouldn't even know you had it and it wont go away on its own you can also ruin your reproductive system you may not be able to conceive if to much damage is done
Yes, it could. It just depends on your body type. You do need to get treated though because Chlamydia can cause infertility and lots of other health probs.
