Half a million new cases of STIs in the UK last year

There were almost half a million new cases of sexually transmitted infections (STIs) in the UK last year, figures show.

Experts at the Health Protection Agency (HPA) say young people are most affected.

The rise is in part due to more testing, and the use of tests which are more sensitive at picking up signs of an infection but experts believe unsafe sexual behaviour is also part of the problem.

Young adults under 25 have the highest rate of infections, and one in ten of those diagnosed contract a further disease within a year.

The BBC's Medical Correspondent Fergus Walsh reports.
