Maine County Battles Historic HIV Outbreak
11 May
Summary
- Penobscot County faces Maine's largest HIV outbreak.
- Cases surged due to homelessness and drug use.
- State and local efforts to expand testing and care are ongoing.

Maine's Penobscot County is experiencing its largest-ever HIV outbreak, with cumulative cases reaching at least 41 as of April 24, significantly exceeding the state's usual annual diagnoses. The public health situation, first identified as a cluster in October 2023, has been exacerbated by increasing homelessness, drug use, and a decline in syringe service and healthcare providers.
Public health officials acknowledge the full scope remains uncertain, as the number of infections likely exceeds current tracking capabilities. The outbreak primarily affects individuals who inject drugs and are unhoused, but also poses risks through sex work. The Maine Center for Disease Control and Prevention is collaborating with national experts to model the outbreak's trajectory.
In response, the state has expanded HIV and Hepatitis C testing, prevention services, and harm reduction initiatives. Locally, Bangor's public health department is enhancing testing, distributing self-tests, and establishing case management programs, including applying for syringe service certification. Bangor aims to leverage its experience to assist other Maine communities potentially facing similar risks.
