HERPES, genital warts and chlamydia are among sexually transmitted diseases on the increase in Medway, according to new figures.

The genito urinary unit at Medway Maritime Hospital dealt with 361 cases of chlamydia in 2008 in the 16 to 24 age group, compared to 228 in 2006, a rise of 69 per cent.

In addition, the number of patients diagnosed with genital warts in the same age group rose by 60 per cent, from 204 in 2006 to 293 in 2008.

Herpes, the third most common sexually transmitted infection seen at Medway, increased from 62 to 86 in the same period.

Consultant Chula Wijesurendra said: "We've seen a marked increase in people being diagnosed with sexually transmitted infections – last year alone there were more than 10,000 appointments altogether to our department.

"While it is good news that people are getting themselves checked and treated, it is a little alarming as it means there are still many people taking risks with their sexual health.

"Be safe – this means using contraception when having sex such as a condom or barrier protection, but also getting yourself tested if you have put yourself at risk.

"This prevents any infections from being inadvertently passed on to another partner and can prevent any future complications – if left untreated, Chlamydia can cause infertility."

Patients do not need a doctor's referral to be treated at the genito urinary unit.

It is open from 9am to 4pm at level three in the green zone.
