Did you know?

As many as 70% of women and 50% of men who have an STI, don't show any symptoms.

If you have unprotected sex (sex without a condom), you have a much greater chance of getting a STI like chlamydia, syphilis, gonorrhoea and HIV.

There are an estimated 20,000 HIV positive people in the UK who don't know they've got HIV.

In the last 10 years, the number of people infected with chlamydia has increased by 206%. In some high-risk groups, such as gay men, the number of people infected with syphilis has increased by 1,949%.
