Please review this information and clinical guidance from the U.S. CDC on testing available for patients with suspected hantavirus, including Andes virus (Orthohantavirus andesense). As of May 19, 2026, there are no known cases of Andes virus in Maine or known exposed travelers returning to Maine. The risk to the general public is extremely low.
All Maine health care facilities, including outpatient clinics and urgent care centers, should prepare to identify, isolate, and inform key partners if/when a patient/client presents with possible Andes virus (signs or symptoms of Andes virus disease and contact with a suspect or confirmed case in the past 42 days).
Suspected cases should be placed in an airborne infection isolation room (AIIR), and heath care personnel should don gown, gloves, eye protection, and an N95 or higher-level respirator when entering the patient’s room until Andes virus can be ruled out. If no AIIR is available (e.g., urgent care, clinic) then place the patient in a private room with the door closed as soon as possible.
