Lassa fever, a viral haemorrhagic fever with symptoms similar to those of Ebola virus disease, is endemic in much of West Africa and usually sparks a seasonal outbreak from December to March. Humans usually become infected with Lassa virus from exposure to urine and faeces of infected Mastomys rats.... Lassa virus may also be spread between humans through direct contact with the blood, urine, faeces or other bodily secretions of a person infected with Lassa fever.
These materials provide a general introduction to Lassa fever and are intended for personnel responding to outbreaks in complex emergencies or in settings where the basic environmental infrastructures have been damaged or destroyed.

This article summarises the process involved in developing the updated guideline and includes an infographic to highlight key IPC recommendations from the guideline, following the patient care pathway from the community to a healthcare facility to discharge.
Issue Brief No. 40 provides healthcare professionals with the most relevant treatment guidelines, prevention measures and training material on MVD
- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

Prevention Guidelines on Marburg virus disease
The primary objective of this curriculum is to equip health and care workers with the essential knowledge and competencies necessary for delivering safe and effective care. By doing so it aims to significantly reduce HAIs and combat antimicrobial resistance, thereby safeguarding both patient and HCW...s well-being.
This curriculum is developed to meet the needs of IPC professionals responsible for developing learning resources and overseeing training within health care organizations. Moreover, the curriculum is intended to encompass all individuals involved in health care delivery and support. This holistic approach includes a wide range of staff -ranging from clinical workers to administrative and auxiliary services, thus ensuring a broad and inclusive approach to IPC training.

The West African Ebola virus disease (EVD) outbreak in 2014 emerged in a region in Africa that had previously not reported any EVD outbreak. Subsequently, the outbreak rapidly spread and was protracted in the three Mano River basin countries (Guinea, Sierra Leone and Liberia), with spillover cases i...n Nigeria, Senegal and Mali and, for the first time, importation into Europe and the USA. It became the most extensive and protracted EVD outbreak in history, followed by the 2018 outbreak in the Democratic Republic of the Congo (DRC). For the first time, cases were reported in urban centers, underscoring the urban spread of the disease. Its devastation had a far-reaching impact on lives in the three largely affected countries for years to follow. A total of 28,616 cases and 11,310 deaths were reported from Guinea, Sierra Leone and Liberia, with an additional 36 cases reported from Italy, Mali, Nigeria, Senegal, Spain, the UK and the USA.

Marburg and Ebola are filoviruses that cause hemorrhage, multiple organ failure, and high mortality rates. Diagnosis is with enzyme-linked immunosorbent assay, polymerase chain reaction (PCR), or electron microscopy. Treatment is supportive. Strict isolation and quarantine measures are necessary to ...contain outbreaks.

Ebola disease and Marburg disease outbreaks continue to occur in Africa, with increased frequency. In addition to resulting in high mortality and morbidity, the outbreaks generate fear and mistrust about the response activities within the communities affected.
Infection prevention and control (IP...C) is a key pillar in the outbreak response; adherence to IPC practices can prevent and control transmission of infections to health and care workers, patients and their family members.
During the 2014-2016 West African Ebola disease outbreak, there was an urgent need for rapid IPC guidance to help support ministries of health, health-care providers and non-governmental organizations (NGOs). In response, WHO produced several documents related to the outbreak based on expert opinion, including IPC-specific documents and documents on clinical management that also referenced key IPC principles and practices. Since that time, many practices in the field have become institutionalized.

The WHO Ebola Virus Disease (EVD) Clinical management: living guidance contains the Organization’s most up-to-date recommendations for the clinical management of people with EVD. Providing guidance that is comprehensive and holistic for the optimal care of patients with EVD throughout their il...lness is important.
The living guidance is available in both pdf format (via the ‘Download’ button) and via an online platform in both French and English, and is updated regularly as new evidence emerges.
This first version of the Clinical management for EVD living guidance contains four new recommendations regarding use of therapeutics for EVD, this includes two strong recommendations for the use of monoclonal antibody therapies. This new living guideline is written to accompany the optimized supportive care (oSoC) for EVD standard operating procedures (5, 6). The living guideline aims to summarize high quality evidence for EVD therapeutics and make recommendations for their use.
