The most important thing to know about Chlamydia is that any one who is having sex is vulnerable. You only need to have unprotected sex with one person who has infection to catch it; but of course, more partners you have, more likely you are to be infected. During 2001, there were more than 71,000 new reported cases, highest level ever and a 10 % rise from 2000.

According to Public Health laboratory Service figures it is estimated that one in ten under 25 year olds now have infection.

If you are over 25 and have had two partners within a year, or recently changed partners your risk increases.

One of most alarming problems with Chlamydia is that it is asymptomatic; that is to say most people don’t know that they have it in early stages. This means that it is very easily passed on without people knowing. Some warning signs could be:

Communication The best way to tell if your relationship is a healthy one is by asking yourself, "How easy it is to talk to my partner, and how honest can I be with him/her?" Finding time to talk, being as open as you can, listening to whole message and being able to work out disagreements are all signs that you are in a healthy relationship.

Respect A healthy relationship is one in which both partners treat each other with respect. Listening to each other’s views and opinions are ways of showing respect. This includes sharing parental responsibilities, making family decisions together and mutually agreeing on a fair distribution of work.
