In the fall of 2017, the Illinois Department of Public Health (IDPH) issued a memo regarding multiple outbreaks of hepatitis A in the U.S. So far in 2018, many of these outbreaks are still ongoing and additional outbreaks have been reported in several states such as Indiana, Michigan and Kentucky. These outbreaks are predominantly occurring in the homeless populations and in persons who use injection and non-injection drugs (IDU), along with close contacts of both groups. Additional outbreak clusters have also been identified in men who have sex with other men (MSM) and persons who are or have recently been incarcerated. On June 5, 2018, IDPH sent a memo to local health departments and medical providers encouraging the continuation of testing, reporting and vaccination of populations at risk for Hepatitis A.
