DOCTOR'S VIEWS ARCHIVE
Dr. Edward Block:
At this time, the principal risk for acquiring hepatitis C appears to be the use of injection drugs, primarily IV drug abuse. IV drug users comprise upwards of 40% of those who are diagnosed with new cases of hepatitis C. Other high-risk activities include other drug use (including intra-nasal cocaine use). People with multiple sex partners are also considered to be at high risk (although the actual risk of sexual transfer of this disease is thought to be relatively low).
There is probably some small risk of sexual transmission here and certainly it would be prudent to tell our viewers that if they are known to be hepatitis C positive and are single that they should take appropriate precautions, such as the use of condoms.
