Penobscot County’s HIV outbreak has reached 43 confirmed cases after two new diagnoses were reported in April, according to Bangor Daily News reporting based on Maine CDC information.
The outbreak began in October 2023 and has primarily affected people who inject drugs and people who are unhoused, according to Maine CDC-linked guidance and reporting. Officials say the confirmed total may still understate the full spread of infections.
Maine CDC’s outbreak page said Penobscot County had 30 confirmed outbreak cases in its Nov. 6, 2025 update and that the agency updates counts weekly. The latest public reporting marks the clearest new milestone since then.
Health officials have responded with expanded testing, prevention services, syringe services and linkage to care. Maine CDC guidance also emphasizes HIV and hepatitis C testing recommendations for people with ongoing injection risk, along with treatment access, PrEP and PEP.
Bangor public health officials have also pointed residents to testing and case-management resources as the outbreak continues to be monitored.
What happens next
The case count remains under active surveillance, and Maine CDC-linked reporting says officials expect more monitoring as new data are posted. The latest update does not indicate the outbreak has ended.
