Marburg virus disease is characterized by a hemorrhagic fever. There have been past outbreaks of this illness as well as isolated cases that have resulted in high mortality. The clinical presentation typically consists of a progressive disease with fever, hemorrhagic manifestations, multiorgan failure, shock, and other serious complications.
Presentation
Marburg virus disease, also known as Marburg hemorrhagic fever, is a severe illness with a high mortality rate. The responsible pathogen, Marburg virus, is a member of the filoviridae family along with the Ebola virus [1]. The first documented outbreak of this disease was in 1967 in Germany and Yugoslavia (which is currently known as Serbia) [2]. Outbreaks have also occurred between 1998 to 2000 in the Democratic Republic of Congo, Angola in 2004 to 2005 [3] [4] and most recently in Uganda in 2012. Additionally, there have been sporadic cases over the years. The African fruit bat acts as a reservoir for this zoonotic virus affecting human as well as non-human primates. The transmission occurs from human to human contact. The incubation period may range from 2 days to 3 weeks [5].
There are three stages of this illness, which are described as the 1) generalization phase, 2) early organ phase, and 3) late organ or convalescence phase [6]. The first phase lasts about 5 days and is characterized by a high fever, headache, chills, malaise, myalgia, and possibly nausea, emesis, watery diarrhea, abdominal pain, pharyngitis, conjunctivitis, and a rash [2] [7] [8]. As the illness progresses, the patient enters the early organ phase, which involves the liver, kidneys, and pancreas. It features neurological symptoms, impaired mental status, hematemesis, bloody diarrhea, and bleeding from other sites [2] [9]. The final phase is critical and often leads to death secondary to critical manifestations such as multiorgan failure, seizures, coagulopathy, cardiovascular collapse, and shock [1].
Physical exam
Assessment of the vital signs typically reveals fever, hypotension and other abnormalities. Also, the patient appears ill and exhibits mental status changes such as confusion, delirium, and dementia [1]. Other notable findings include conjunctival injection, pharyngitis, petechia, ecchymoses, and palatal exanthem. Bleeding from mucosal sites and orifices is observed in severe cases.

Workup
Patients presenting with the above symptoms warrant a thorough evaluation consisting of a detailed personal and travel/exposure history, physical exam, and the appropriate studies.
Laboratory tests
A complete blood count (CBC) and complete metabolic panel (CMP) including liver function tests (LFTs) will feature typical findings such as leukopenia, thrombocytopenia, and elevated liver transaminases. Furthermore, a coagulation panel and disseminated intravascular coagulation profile will reveal abnormalities about the patient's critical state.
Diagnostic tests
Viral detection studies such as reverse transcription polymerase chain reaction (RT–PCR) and enzyme-linked immunosorbent assay (ELISA) are the first-line tests [10]. In addition to conventional RT-PCR, quantitative real-time RT-PCR is also used [1] [11].
Other studies such as immunoglobulin (Ig) M and IgG ELISA are used to identify antibodies against the virus [1]. Moreover, IgM–capture ELISAs are commonly performed for the diagnosis of acute disease while IgG antibodies are used retrospectively post-disease [12]. Additionally, there is a promising future for the reverse transcription–loop–mediated isothermal amplification method in diagnosing Marburg virus [13].
There are two other techniques, virus isolation, and electron microscopy, but these are limited to specialized sites [1].
Treatment
Guided tours of the Marburg treatment units in Kapchorwa and Kween were organized in order to dispel fear of the treatment center and rumours of wrong practices by healthcare workers that cause death of admitted patients. [who.int]
Patients expect injections and iv treatment in this area of Angola, and the number of individuals presenting to the Marburg ward for assessment increased after these treatment measures were introduced. [doi.org]

Etiology
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]
It was soon apparent that the infectious agent was neither bacterial nor rickettsial in origin but that a viral etiology was probable. [link.springer.com]
The admission diagnosis was acute hepatitis, nausea, and vomiting of unknown etiology. On admission, the patient was afebrile (temperature 96.2 F [35.7 C]). [cdc.gov]
Only six secondary infections (five nosocomial and one sexually transmitted) were noted of the 32 cases reported during the original MHF outbreak in 1967 in Europe, despite the fact that the etiologic agent was unknown at the time of the outbreak and [doi.org]
Epidemiology
This underlines the importance of a community surveillance system that provides epidemiological data on prior patient contacts and of integrating epidemiological data into the clinical assessment when deciding on isolation or PCR testing. [doi.org]
The analysis was severely hampered by a lack of completeness in epidemiologic data. [ncbi.nlm.nih.gov]
The WHO and international partners, including the CDC, the Uganda Red Cross, African Field Epidemiology Network and Médecins-Sans-Frontières, are supporting the national authorities in outbreak investigation and response. [healio.com]
The response was supported by WHO, UNICEF, USAID, World Vision, Uganda Red Cross, Médecins Sans Frontières (MSF), the African Field Epidemiology Network (AFENET) and the US Centers for Disease Control and Prevention (CDC). [who.int]
Pathophysiology
Pathophysiology Once the virus enters the body though breaks in the skin or mucous membranes, it infects dendritic cells and macrophages which then carry it to lymph nodes. [upmc-cbn.org]
However, their mimicry of the human diseases as well as their predictive value for therapeutic efficacy in primates is limited, thereby making them, at best, valuable initial screening tools for pathophysiology, treatment and vaccine studies. [dmm.biologists.org]
Novel viruses have recently been identified. [6, 7] Pathophysiology Although common themes occur, the different viruses display variable pathophysiology. [emedicine.com]
Pathophysiology The three viruses are intracellular pathogens capable of infecting many different cell types. [patient.info]
Ebola virus (EBOV) infection is characterized by an excessive inflammatory response, a loss of lymphocytes and a general paralysis of the immune system, however pathophysiological mechanisms are not fully understood. [mdpi.com]
Prevention
Training of health workers on infection prevention and control, surveillance and clinical case management is ongoing, and the first shipment of personal protective equipment arrived recently. [healio.com]
How is Marburg hemorrhagic fever prevented? Due to our limited knowledge of the disease, preventive measures against transmission from the original animal host have not yet been established. [web.archive.org]
