It appears NZ is in the middle of a Chlamydia epidemic and young woman are the demographic most at risk. As it is such a widespread infection in NZ many cases are going undetected and thus adding to the rate of infection. Certain age groups and geographical locations are more at risk but it is an extremely common infection and is very easily transmitted. Luckily it is easily detected and treated if detected in time. Early symptoms include pain while urinating but many have no symptoms at all. Detection can be via self-test or rapid test kits as sold by online vendors such as www.testmyhealth.co.nz.

If you have had unprotected sex, have symptoms or are worried about any sexually transmitted infection then rapid test kits for home use can be an ideal way to test privately and conveniently.
