What is Chlamydia?
Chlamydia is a sexually transmitted infection that affects both men and women. It is a bacteria which is passed from one person to another by having sex, especially sex where you aren’t taking a contraceptive pill and using a condom. Being on the pill to prevent pregnancy doesn’t stop you catching a sexually transmitted infection.
Chlamydia is very common, with around one in ten people under 25 who are tested having the infection. Most people will not have any obvious signs or symptoms so they won’t know they have it. You also won’t be able to spot signs in a partner, which is why chlamydia is often called an ‘invisible’ infection. All under 25s who are sexually active are being encouraged to test for chlamydia every year, and every time they change partner, to make sure they are clear. In many cases these tests are free and in some cases can be obtained without the knowledge of your doctor.
