the answer is yes. you can have it quite a while even longer than a year. not knowing if you are a male or female i will address both: the symptoms of chlamydia in men can be subtle or the person may have burning with urination or a mucous-like discharge. some men are more attentive than others so i have met people that have ignored symptoms for quite a long time only to test positive. in women chlamydia may not be noticed at all or the symptoms are so non-specific that they too will ignore. since chlamydia can lead to a very serious pelvic infection (called a pid - pelvic inflammatory disease) many times this is the first time it is diagnosed. chlamydia can scar the tubes and predispose the woman to a tubal pregnancy. clearly the illness is more serious for a woman if it goes undiagnosed. if all couples would just agree to safe sex practices chlamydia and many other stds would become rare. unfortunately they are not.
can you have a chlamydia infection go undetected for more than one year?
