The World Health Organization’s Regional Office for Africa reported that Ethiopia has officially declared the end of its first-ever outbreak of Marburg virus disease after completing enhanced surveillance and the required follow-up period with no new confirmed cases for 42 consecutive days. The outbreak was first confirmed on November 14, 2025, in Ethiopia’s South Ethiopia Region, and the end-of-outbreak declaration was announced on January 26, 2026.
WHO said the outbreak was contained in less than three months through a coordinated response led by Ethiopian authorities and supported by international partners. The response covered the full chain of outbreak control: detecting cases quickly, isolating and treating patients, tracing contacts, strengthening infection prevention and control in healthcare settings, and communicating risk information in communities to reduce exposure.
In its update, WHO described its support to Ethiopia’s Ministry of Health and the Ethiopian Public Health Institute (EPHI) across multiple operational pillars, including leadership and coordination, surveillance, laboratory work, case management, infection prevention and control, logistics, and risk communication and community engagement. These pillars are typically essential in halting transmission of hemorrhagic fevers, where delays in diagnosis and unsafe care settings can accelerate spread.
Marburg virus disease is a severe illness that can spread through direct contact with infected bodily fluids and contaminated surfaces. Outbreak control depends heavily on rapid identification of suspected cases, safe patient transport and isolation, proper protective equipment for healthcare workers, and careful monitoring of contacts for symptoms. Because symptoms can initially resemble other infections, laboratory confirmation and field surveillance are critical.
Public-health officials note that the 42-day window matters because it spans two incubation periods for Marburg, providing a buffer to ensure that any hidden chains of transmission would likely have emerged. Still, WHO and national authorities generally stress that continued preparedness is needed even after an outbreak ends, including strengthened surveillance in affected regions and readiness to respond if a new case appears.
Ethiopia’s end-of-outbreak announcement is also a reminder of the growing importance of regional coordination for infectious-disease threats. Cross-border movement, remote terrain, and limited health infrastructure can complicate containment. The experience may inform future preparedness planning, including laboratory networks, emergency logistics, and community trust-building—factors that often determine whether a hemorrhagic fever outbreak stays small or becomes a wider crisis.
