More than 2.3 million people globally are infected with both HIV and hepatitis C (HCV) viruses finds a new study. Of these more than half or 1.3 million are people who inject drugs (PWID) -- HIV infections caused by injecting drugs. The study revealed that HIV-infected people are on an average six times more likely than HIV-uninfected people to have HCV infection. The study shows that not only are people with HIV at much higher risk of HCV infection groups such as people who inject drugs have extremely high prevalence of HCV infection - over 80 percent said Philippa Easterbrook
