The report, "Does Bleach Disinfection of Syringes Protect Against Hepatitis C Infection Among Young Adult Injection Drug Users?" was published in Epidemiology (2002;13(6)721). According to the authors, among more than 450 drug users studied, those who said they cleaned their needles with bleach all the time were 65 percent as likely to have hepatitis C as those who did not use bleach at all. Participants who said they used bleach "less than all the time" had a 24 percent lower risk of being infected.
Dr. Farzana Kapadia and Dr. David Vlahov, both of the New York Academy of Medicine, were the lead authors. Vlahov said the surest ways to avoid hepatitis C infection were abstaining and using clean syringes. Vlahov suggested that despite its flaws, bleaching might still offer some protection against HIV.
In the early '90s, based on laboratory findings, injection drug users were advised to clean their needles with bleach to protect against HIV. Soon, however, it appeared that although bleach killed HIV in the lab, it was not very effective on the street.
