According to research published today in the British Medical Journal, four in ten new young injectors now has hepatitis C, while three per cent are now infected with HIV.
Hepatitis C, which can cause serious and sometimes fatal liver damage, is mainly spread by sharing needles and syringes. Preventing HCV transmission among injecting drug users is critical to avoiding significant later health consequences in the population and associated treatment costs.
Dr Ali Judd, from Imperial College London, based at Charing Cross Hospital, and one of the authors of the study, comments: "Hepatitis C is now spreading at epidemic levels across London and HIV incidence is worryingly high, which if unchecked will lead to an increase in the total number of HIV infections. There is an urgent need for new and comprehensive programmes to tackle this growing problem."
For the study, the researchers recruited 428 injecting drug users, aged below 30 years or who had been injecting for six years or less, and followed them up one year later. The study was made possible through the use of saliva and blood spot tests for HCV and HIV developed at the Health Protection Agency Centre for Infections. Of those that were HCV negative or HIV negative at the first interview they found 42 percent and 3.4 percent were infected with HCV and HIV respectively one year later. The researchers also found high levels of syringe sharing, with one in four reporting injecting with needles and syringes that had been used by someone else in the last four weeks and one in two sharing other injecting paraphernalia.
