U.S. Centers for Disease Control and Prevention (CDC) staff are actively assisting with the response to an HIV outbreak in Penobscot County, Maine. A team of six CDC employees arrived in the Bangor area on December 12, 2025, and are expected to remain until December 19. This initiative aims to support local and state public health officials as they work to address the growing crisis.
The outbreak, identified over two years ago, predominantly affects individuals who inject drugs or are homeless. As of October 2025, the number of reported cases in Penobscot County reached a concerning total of 30. The CDC’s involvement comes at a critical time, as there have been initial reports of rising HIV cases among people who inject drugs in Cumberland County, outside the immediate outbreak area.
Local Health Officials Seek Federal Support
Public health officials in Maine have expressed the need for federal assistance to gain a comprehensive understanding of the outbreak’s spread. According to Matt Wellington, associate director of the Maine Public Health Association, “In a small state like Maine where it’s not normal for us to have HIV outbreaks of this size, we’re just not equipped to handle it by ourselves.” This sentiment highlights the strain local resources face in managing the situation effectively.
The CDC team includes four epidemic intelligence service officers who will conduct interviews with those affected by the outbreak. They will also develop educational resources for healthcare providers, community partners, and residents. A CDC spokesperson indicated that the agency had previously offered technical assistance on the ground back in August 2025.
During the recent government shutdown, the CDC temporarily paused a request for field epidemiologists to assist in Penobscot County. Although travel was not authorized during this period, the agency has provided similar support in past public health emergencies.
Emerging Challenges in Containing the Spread
The urgency for intervention is underscored by the rising number of HIV cases reported in other parts of Maine. A recent analysis by the Maine CDC identified five new cases in Cumberland County among individuals who inject drugs. As public health officials in the Portland area prepare for a potential increase in cases, they are working to enhance access to testing and other essential resources.
The ongoing outbreak has raised alarms among health officials, who are keenly aware that the ramifications could extend beyond Penobscot County if not addressed promptly. The concerted efforts of the CDC, along with state and local health departments, aim to contain the outbreak and prevent further transmission of the virus.
As the situation evolves, continued collaboration between federal, state, and local health authorities will be crucial in managing this public health crisis effectively. The presence of CDC personnel in the Bangor area signals a proactive approach to mitigating the impact of the outbreak and safeguarding the health of communities across Maine.
