People who inject drugs (PWID) are more likely to develop hepatitis C. The Centers for Disease Control and Prevention (CDC) points out that the virus can survive on equipment, such as needles, for up to three weeks. However, some of the different hepatitis C genotypes are more prominent in certain areas than others. A report published in the Journal of Hepatology uncovered the distribution of hepatitis C genotypes by continent in PWID.
Geert Robaeys, MD, PhD, and Rob Bielen, MD, from Ziekenhuis Oost-Limburg in Belgium, and colleagues, reviewed 48 studies from 48 countries. The data was collected from 1995 to 2005 from PWID. There are at least six different hepatitis C genotypes and over 50 subtypes, according to the CDC. The most prevalent genotypes were specified by continent:
