In a CDC report, investigators looked at the uptick of Hepatitis A in many states across the country. Those regarded as high risk is where "infections are spreading primarily through close contact among persons who use drugs and persons experiencing homelessness, as well as among men who have sex with men (MSM)" Of interest in the report was the percentage of food handlers, and overall, the percentage of cases associated with food handlers was low (3.8%). Looking at food handlers, a high percentage of them were people in the high risk - people use drugs, have unstable housing or are homeless, are active in MSM, or had been incarcerated.
From the report, "Among 22,825 hepatitis A outbreak cases reported from these 26 states during July 1, 2016–September 13, 2019, 871 (3.8%) were among food handlers; 587 (67.4%) hepatitis A–infected food handlers reported one or more risk factors (i.e., drug use, unstable housing or homelessness, MSM, or incarceration) during the 15–50 days before symptom onset.
