Please review this information and clinical guidance from the U.S. CDC on the Marburg outbreak caused by Marburg virus (Marburg marburgvirus) in Ethiopia’s South Ethiopia and Sidama regions. As of December 15, 2025, there are no known cases of Marburg in Maine or the United States and the risk to people in the United States is low.
Any patients in Maine with suspected Marburg must be reported immediately to the Maine CDC by phone at 1-800-821-5821.
The Maine CDC can provide guidance regarding how to test for Marburg, and how to transfer a patient to another facility, if appropriate. Maine’s Health and Environmental Testing Laboratory (HETL) is equipped to perform norovirus and respiratory virus testing to help identify an alternative etiology.
All Maine health care facilities, including outpatient clinics and urgent care centers, should prepare to identify, isolate, and inform key partners when a patient/client presents with signs or symptoms of Marburg virus disease.
Information and health care facility readiness assessment tools are available from the National Emerging Special Pathogens Training and Education Center (NETEC) at www.netec.org/education-training and the National Special Pathogen System (NSPS) at www.netec.org/nsps.
