Clinical phases of Marburg hemorrhagic fever's presentation are described below. Note that phases overlap due to variability between cases.
# Incubation: 2–21 days, averaging 5–9 days.<ref name=clini/>
# Generalization Phase: Day 1 up to Day 5 from the onset of clinical symptoms. MHF presents with a high fever 104&nbsp;°F (~40˚C) and a sudden, severe headache, with accompanying chills, fatigue, nausea, vomiting, diarrhea, pharyngitis, maculopapular rash, abdominal pain, [[conjunctivitis]], and [[malaise]].<ref name=clini/>
# Early Organ Phase: Day 5 up to Day 13. Symptoms include prostration, [[dyspnea]], [[edema]], [[conjunctival injection]], viral [[exanthema]], and CNS symptoms, including encephalitis, confusion, delirium, apathy, and aggression. Hemorrhagic symptoms typically occur late and herald the end of the early organ phase, leading either to eventual recovery or worsening and death. Symptoms include bloody stools, [[ecchymoses]], blood leakage from [[venipuncture]] sites, mucosal and visceral hemorrhaging, and possibly [[hematemesis]].<ref name=clini/>
# Late Organ Phase: Day 13 up to Day 21+. Symptoms bifurcate into two constellations for survivors and fatal cases. Survivors will enter a convalescence phase, experiencing [[myalgia]], [[fibromyalgia]], [[hepatitis]], [[asthenia]], ocular symptoms, and [[psychosis]]. Fatal cases continue to deteriorate, experiencing continued fever, [[obtundation]], [[coma]], [[convulsions]], diffuse [[coagulopathy]], metabolic disturbances, [[Shock (circulatory)|shock]] and death, with death typically occurring between days 8 and 16.<ref name="clini">{{Cite journal |last=Mehedi |first=Masfique |last2=Allison Groseth |last3=Heinz Feldmann |last4=Hideki Ebihara |date=September 2011 |title=Clinical aspects of Marburg hemorrhagic fever |journal=Future Virol. |volume=6 |issue=9 |pages=1091–1106 |doi=10.2217/fvl.11.79 |pmc=3201746 |pmid=22046196}}</ref>

Further studies are necessary to establish whether Egyptian rousettes are the actual hosts of MARV and RAVV or whether they get infected via contact with another animal and therefore serve only as intermediate hosts. Another risk factor is contact with nonhuman primates, although only one outbreak of MVD (in 1967) was due to contact with infected monkeys.<ref name=Siegert1967/>

== Transmission ==
The details of the initial transmission of MVD to humans remain incompletely understood. Transmission most likely occurs from [[Egyptian fruit bat]]s or another natural host, such as [[non-human primate]]s or through the consumption of [[bushmeat]], but the specific routes and body fluids involved are unknown. Human-to-human transmission of MVD occurs through direct contact with infected bodily fluids such as blood.<ref name="Kortepeter2020" /> Transmission events are relatively rare – there have been only 11 recorded outbreaks of MARV between 1975 and 2011, with one event involving both MARV and RAVV.<ref>{{Citation |last=von Csefalvay |first=Chris |title=Host-vector and multihost systems |date=2023 |work=Computational Modeling of Infectious Disease |pages=121–149 |url=https://linkinghub.elsevier.com/retrieve/pii/B978032395389400013X |access-date=2023-03-05 |archive-url=https://web.archive.org/web/20230418221153/https://www.sciencedirect.com/science/article/abs/pii/B978032395389400013X?via%3Dihub |archive-date=2023-04-18 |url-status=live |publisher=Elsevier |language=en |doi=10.1016/b978-0-32-395389-4.00013-x |isbn=978-0-323-95389-4 |url-access=subscription}}</ref>

== Diagnosis ==
[[File:Marburg virus liver injury.jpg|thumb|Marburg virus liver injury]]
MVD is clinically indistinguishable from [[Ebola virus disease|Ebola virus disease (EVD)]], and it can also easily be confused with many other diseases prevalent in [[Equatorial Africa]], such as other [[viral hemorrhagic fever]]s, [[malaria|falciparum malaria]], [[typhoid fever]], [[shigellosis]], [[rickettsia|rickettsial diseases]] such as [[typhus]], [[cholera]], [[Gram-negative bacteria|gram-negative]] [[sepsis]], [[borreliosis]] such as [[relapsing fever]] or [[Verotoxin-producing Escherichia coli|EHEC enteritis]]. Other infectious diseases that ought to be included in the [[differential diagnosis]] include [[leptospirosis]], [[scrub typhus]], [[plague (disease)|plague]], [[Q fever]], [[candidiasis]], [[histoplasmosis]], [[trypanosomiasis]], [[visceral]] [[leishmaniasis]], hemorrhagic [[smallpox]], [[measles]], and fulminant [[viral hepatitis]]. Non-infectious diseases that can be confused with MVD are [[acute promyelocytic leukemia]], [[hemolytic uremic syndrome]], [[snake]] [[envenomation]], [[coagulation|clotting factor]] deficiencies/platelet disorders, [[thrombotic thrombocytopenic purpura]], [[hereditary hemorrhagic telangiectasia]], [[Kawasaki disease]], and even [[warfarin]] intoxication.<ref name="Gear1989">{{Cite journal |last=Gear |first=J.

The most important indicator that may lead to the suspicion of MVD at clinical examination is the [[medical history]] of the patient, in particular the travel and occupational history (which countries and caves were visited) and the patient's exposure to wildlife (exposure to bats or bat excrements). MVD can be confirmed by isolation of marburgviruses from or by detection of marburgvirus antigen or genomic or subgenomic RNAs in patient [[blood]] or [[Blood serum|serum]] samples during the acute phase of MVD. Marburgvirus isolation is usually performed by [[inoculation]] of [[grivet]] kidney epithelial [[Vero cell|Vero E6]] or MA-104 [[cell culture]]s or by inoculation of human adrenal carcinoma SW-13 cells, all of which react to infection with characteristic [[cytopathic effect]]s.<ref name="Hofmann1968">{{Cite journal |last=Hofmann |first=H. |last2=Kunz |first2=C. |year=1968 |title="Marburg virus" (Vervet monkey disease agent) in tissue cultures |journal=Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. 1.

=== Classification ===
Marburg virus disease (MVD) is the official name listed in the [[World Health Organization]]'s [[International Statistical Classification of Diseases and Related Health Problems]] 10 (ICD-10) for the human disease caused by any of the two marburgviruses; [[Marburg virus]] (MARV) and [[Ravn virus]] (RAVV). In the scientific literature, Marburg hemorrhagic fever (MHF) is often used as an unofficial alternative name for the same disease. Both disease names are derived from the [[Germany|German]] city [[Marburg]], where MARV was first discovered.<ref name="Siegert1967">{{Cite journal |last=Siegert |first=R. |last2=Shu |first2=H.

== Prevention ==
{{Main|Prevention of viral hemorrhagic fever}}
Marburgviruses are highly [[infection|infectious]], but not very [[Contagious disease|contagious]]. They do not get transmitted by [[aerosol]] during natural MVD outbreaks. Due to the absence of an approved vaccine, prevention of MVD therefore relies predominantly on [[quarantine]] of confirmed or high probability cases, proper [[personal protective equipment]], and [[sterilization (microbiology)|sterilization]] and [[disinfection]].{{citation needed|date=October 2017}}

=== Vaccine development ===
{{main|Marburg vaccine}}
There are currently no [[Food and Drug Administration]]-approved [[vaccine]]s for the prevention of MVD.

=== Endemic zones ===
The natural maintenance hosts of marburgviruses remain to be identified unequivocally. However, the isolation of both MARV and RAVV from [[bat]]s and the association of several MVD outbreaks with bat-infested mines or caves strongly suggests that bats are involved in Marburg virus transmission to humans. Avoidance of contact with bats and abstaining from visits to caves is highly recommended, but may not be possible for those working in mines or people dependent on bats as a food source.{{citation needed|date=October 2017}}

=== During outbreaks ===
Since marburgviruses are not spread via aerosol, the most straightforward prevention method during MVD outbreaks is to avoid direct (skin-to-skin) contact with patients, their [[excretion]]s and [[body fluids]], and any possibly [[contamination|contaminated]] materials and utensils. Patients should be isolated, but still are safe to be visited by family members. Medical staff should be trained in and apply strict barrier nursing techniques (disposable face mask, gloves, goggles, and a gown at all times). Traditional [[burial]] rituals, especially those requiring [[embalming]] of bodies, should be discouraged or modified, ideally with the help of local [[traditional healer]]s.<ref>{{Cite book |last=Centers for Disease Control and Prevention and World Health Organization |url=https://www.cdc.gov/ncidod/dvrd/spb/mnpages/vhfmanual/entire.pdf |title=Infection Control for Viral Haemorrhagic Fevers in the African Health Care Setting |publisher=Centers for Disease Control and Prevention |year=1998 |location=Atlanta, Georgia, USA |ref=CITEREFCDCWHO1998 |access-date=2009-05-31 |archive-url=https://web.archive.org/web/20090507233051/http://www.cdc.gov/ncidod/dvrd/spb/mnpages/vhfmanual/entire.pdf |archive-date=2009-05-07}}</ref>

== Treatment ==
There is currently no effective marburgvirus-specific [[therapy]] for MVD. Treatment is primarily supportive in nature and includes minimizing invasive procedures, balancing fluids and [[electrolyte]]s to counter [[dehydration]], administration of [[anticoagulants]] early in infection to prevent or control [[disseminated intravascular coagulation]], administration of [[coagulation|procoagulants]] late in infection to control [[bleeding|hemorrhaging]], maintaining [[oxygen]] levels, [[pain management]], and administration of [[antibacterial|antibiotics]] or [[antifungal medication|antifungals]] to treat secondary infections.<ref>{{Cite journal |last=Bausch |first=D.

=== 1967 outbreak ===
{{main|1967 Marburg virus disease outbreak}}

MVD was first documented in 1967, when 31 people became ill in the [[Germany|German]] towns of [[Marburg]] and [[Frankfurt am Main]], and in [[Belgrade]], [[Socialist Federal Republic of Yugoslavia|Yugoslavia]]. The outbreak involved 25 primary MARV infections and seven deaths, and six nonlethal secondary cases. The outbreak was traced to infected [[grivet]]s (species ''Chlorocebus aethiops'') imported from an undisclosed location in [[Uganda]] and used in developing [[poliomyelitis]] [[vaccines]]. The monkeys were received by Behringwerke, a Marburg company founded by the first winner of the [[Nobel Prize in Medicine]], [[Emil von Behring]]. The company, which at the time was owned by [[Hoechst AG|Hoechst]], was originally set up to develop [[blood plasma|sera]] against [[tetanus]] and [[diphtheria]]. Primary infections occurred in Behringwerke [[laboratory]] staff while working with grivet tissues or tissue cultures without adequate [[personal protective equipment]]. Secondary cases involved two [[physician]]s, a [[nurse]], a post-mortem attendant, and the wife of a [[veterinarian]]. All secondary cases had direct contact, usually involving blood, with a primary case. Both physicians became infected through accidental skin pricks when drawing blood from patients.<ref name="Kissling1968">{{Cite journal |last=Kissling |first=R. E. |last2=Robinson |first2=R.

=== 2004–2005 outbreak ===
In early 2005, the [[World Health Organization]] (WHO) began investigating an outbreak of [[viral hemorrhagic fever]] in [[Angola]], which was centered in the northeastern [[Uíge Province]] but also affected many other provinces. The Angolan government had to ask for international assistance, as there were only approximately 1,200 doctors in the entire country and provinces that had few as two. Health care workers also complained about a shortage of basic [[personal protective equipment]]. [[Médecins Sans Frontières]] (MSF) reported that when their team arrived at the provincial hospital at the center of the outbreak, they found it operating without water and electricity. [[Contact tracing]] was complicated by the fact that the country's roads and other infrastructure were devastated after nearly three decades of [[Angolan War of Independence|civil war]] and the countryside remained littered with [[land mine]]s.<ref name="Roddy2010" />

Americo Boa Vida Hospital in the Angolan capital, [[Luanda]], set up a special isolation ward to treat patients from the countryside. Due to the high fatality rate of MVD, some people came to be suspicious of and hostile towards hospitals and medical workers. For instance, a specially-equipped isolation ward at the provincial hospital in Uíge was reported to be empty during much of the epidemic, even though the facility was at the center of the outbreak. WHO was forced to implement what it described as a "harm reduction strategy" by distributing disinfectants to affected families who refused hospital care. Of the 252 people who contracted MVD, 227 died.<ref name="Roddy2010">{{Cite journal |last=Roddy |first=P. |last2=Thomas |first2=S.

=== 2007 cases ===
In 2007, four [[miner]]s became infected with marburgviruses in [[Kamwenge District]], [[Uganda]]. The first case, a 29-year-old man, became symptomatic on July 4, 2007, was admitted to a hospital on July 7, and died on July 13. Contact tracing revealed that the man had had prolonged close contact with two colleagues (a 22-year-old man and a 23-year-old man), who experienced clinical signs of infection before his disease onset. Both men had been admitted to hospitals in June and survived their infections, which were proven to be due to MARV. A fourth, 25-year-old man, developed MVD clinical signs in September and was shown to be infected with RAVV. He also survived the infection.<ref name=Towner2009/><ref name="Adjemian2011">{{Cite journal |last=Adjemian |first=J. |last2=Farnon |first2=E. C. |last3=Tschioko |first3=F. |last4=Wamala |first4=J.
