A male patient reported onset of symptoms on 25 July 2021, dying on 2 August. The case is located in the Guéckédou Prefecture, Nzérékoré Region, and is the first known case of MVD in Guinea and West Africa.

  1. Coordiantion between the Guinean Ministry of Health (MoH), WHO, US Centers for Disease Control and Prevention, Alliance for International Medical Action (ALIMA), Red Cross, UNICEF, the International Organization for Migration (IOM) and other partners, have initiated measures to control the outbreak and prevent further spread.
  2. Contact tracing is ongoing, along with active case searching in health facilities and at the community level.
  3. Following the recent declaration of the end of a Ebola virus outbreak in Guinea on 19 June 2021, a community health workers network and a WHO technical team that were supporting the government’s post-Ebola surveillanc is being repurposed to tackle the MVD outbreak.
  4. A public health emergency operations center has been activated and a base to support response workers will be set up in the sub-prefecture of Koundou.
  5. Active searching for suspected cases in the community and health facilities is ongoing.
  6. A surveillance team has been deployed and briefings for health workers are underway, with particular focus on the village where the index case was identified along with villages within a 15 kilometer radius.
  7. Point of entry surveillance is being reinforced and two health control entry points were recently revitalized (Kiesseneye and Nongoa). The three main entry points with Sierra Leone and Liberia are active and the others are under evaluation.
  8. In collaboration with ALIMA, there is an ongoing assessment of the case management capacity in the health facilities.
  9. Risk communication activities are ongoing in the community.
  1. Health workers should always implement standard precautions during patient care, regardless of their presumed diagnosis. These include hand hygiene, respiratory hygiene and cough etiquette, use of risk based personal protective equipment (PPE), safe injection practices, environmental cleaning and disinfection, appropriate linen and waste management, and decontamination of reusable medical equipment.
  2. Health workers caring for patients with suspected or confirmed Marburg virus should apply additional precautionary infection control measures to prevent contact with the patient’s body fluids and/or contaminated surfaces. This includes the following PPE items: face protection (a face shield or a medical mask and goggles), a clean, non-sterile long-sleeved gown, and gloves. This further emphasizes the importance of readily available PPE at health care facilities, appropriate donning/doffing areas, IPC/WASH supplies and training on their proper uses.
  3. Surveillance activities, including contact tracing and active case searching, must be strengthened within all affected health zones.
  4. Risk communication and community engagement (RCCE) is key to successfully controlling outbreaks.
  5. Based on the current risk assessment and prior evidence on Ebola outbreaks, WHO advises against any restriction of travel and trade to and from Guinea.
