GONORRHEA rates have shot up in Hounslow but there has been a fall in other sexually transmitted infections in the borough, new figures show.
The number of people diagnosed with gonorrhea in Hounslow per 100,000 population increased 40 per cent, from 51.4 in 2011 to 71.8 last year, according to statistics from government watchdog Public Health England (PHE).
However, the numbers infected with herpes, syphilis, genital warts and chlamydia all fell, with cases of syphilis down more than a third to 5.5 per 100,000 people.
The overall rate of STIs in the Hounslow last year was 807.7 per 100,000, the 10th lowest of all 32 London boroughs, with no comparable figure for 2011.
Gonorrhea was up by 27 per cent across London, where overall STI rates were 74 per cent higher than any other region, with 111,451 new cases diagnosed last year.
Rising gonorrhea rates are particularly concerning, according to PHE, as resistance to antibiotics is growing globally.
Dr Paul Crook, an STI epidemiologist for PHE London, said the increased rates of detection were partly down to screening improvements but the high rate of STIs among men who sleep with men was worrying.
"If they are having unprotected sex with casual or new partners they should have an HIV and STI screen at least annually, and every three months if they are changing their partners regularly," he added.
