Free Chlamydia tests will be offered to anyone aged 15-24
Punters at this year's Glastonbury Festival, headlined by Blur, Bruce Springsteen and Neil Young, are to be offered free Chlamydia tests.
Anyone aged between 15 and 24 will be able to visit a screening centre at six "information points" around the site at Worthy Farm in Somerset.
The sexually transmitted infection (STI) has no symptoms in more than half of men and 70% of women.
If left untreated Chlamydia can cause major infertility problems.
One in 12 sexually active people between 15 and 24 in the UK test positive and it's the UK's fastest spreading sexual infection.
Anyone returning a DIY urine test kit at Glastonbury will get a free glow-in-the-dark sperm key ring or glow-in-the-dark condom.
Sara Dove, NHS Chlamydia screening service manager, said: "The service is completely free [for Somerset residents], confidential and easy and so are the test results.
"People can choose how to receive their result (a discreet message by text or email, a letter or by phone).
"For those testing positive the treatment is simple and painless, just four antibiotic tablets taken at once."
Glastonbury takes place between 26-28 June and also features bands such as Kasabian, Dizzee Rascal, Franz Ferdinand, The Prodigy and Black Eyed Peas.
