"According to the latest report from the United Nations Office on Drugs and Crime (UNODC), an estimated 11.3 million people inject drugs globally, while HIV prevalence is estimated to be 12.6% and hepatitis C prevalence 48.5% among this population. However, while 179 of 206 countries report some injecting drug use, 110 countries and territories worldwide have no data on its prevalence. This data gap highlights the need for more and higher quality data to inform our efforts to implement appropriate harm reduction services that can address public health issues, including HIV and hepatitis C, soft tissue infections, and overdose."
