The research, published in The Lancet, found that although general practitioners (GPs) were able to increase testing among 16 to 29 year olds by 150% over a three-year period, it did not reduce the overall proportion contracting chlamydia. «This trial shows that evidence-based control of chlamydia and its complications will need more than just increased testing. Better clinical management of people with diagnosed chlamydia, treatment of sexual partners, and prevention of re-infection, are also needed», says ISPM’s Professor Nicola Low, the senior author of the report.
