A community clinic's response to a hepatitis A outbreak.

The current hepatitis A outbreak in San Diego County, largely among homeless individuals and illicit drug users, prompted a community clinic to vaccinate at-risk patients. The clinic marshaled the efforts of multiple departments to educate and vaccinate 7,521 adults in 7 months. Strong support from executive leaders, coordinated efforts from various departments, and leveraged relationships with other community organizations and public health officials are key factors of a strong response to a public health concern.
