91色情片 workers in Pakistan are spreading hepatitis C through contaminated
injections, doctors fear. A team from Aga Khan University in Karachi
investigated 74 patients in Hafizabad infected with the hepatitis C virus. These
people were 12 times as likely to have received four or more injections per year
as uninfected members of their households. The team concludes that injections,
rather than contact with sufferers, are the main source of infection (
Epidemiology and Infection, vol 123, p 515).
