Health officials initially said a single pediatrician who was accused of reusing syringes was to blame, according to The [NY] Times. Ghanghro was ultimately arrested and charged with negligence, manslaughter and causing unintentional harm. He has yet to be convicted and has maintained his innocence, saying he never reuses syringes. Health officials say that Ghanghro is not likely to be the sole cause of the outbreak, noting that visiting health workers saw many other doctors reuse syringes, barbers use the same razors to shave customers, and roadside dentists use unsterilized tools.
