Counties and Jurisdictions Experiencing or At-Risk of Outbreaks

At a glance

A 2014-2015 outbreak of HIV infection among a rural network of persons who inject drugs (PWID) underscored the intersection of the expanding crises of opioid misuse, injection drug use, and associated increases in bloodborne infectious diseases.

What CDC is doing

The Centers for Disease Control and Prevention (CDC) conducted a national assessment to identify U.S. communities potentially vulnerable to rapid spread of HIV, if introduced, and new or continuing high rates of hepatitis C virus infections among PWID. Jurisdictions also consulted with CDC and provided evidence that their jurisdiction is experiencing or at risk for significant increases in hepatitis infections or an HIV outbreak due to injection drug use.
