2. Epidemiological Link: A history of exposure to the Marburg virus is crucial for diagnosis. This includes:
   - Recent travel to areas where MVD outbreaks have occurred, particularly in Africa.
   - Contact with infected individuals or animals, such as fruit bats or non-human primates, which are known reservoirs of the virus[3][4].

Laboratory Criteria

1. Viral Detection: Laboratory confirmation is essential for a definitive diagnosis. This can be achieved through:
   - Polymerase Chain Reaction (PCR): This test detects the genetic material of the Marburg virus in blood or other body fluids.
   - Serological Testing: Detection of antibodies against the Marburg virus can also support diagnosis, although this may not be effective in the early stages of the disease[5][6].

2. Isolation of the Virus: In some cases, isolating the virus from a clinical specimen can confirm the diagnosis, although this is typically performed in specialized laboratories due to the high risk associated with handling the virus[7].

   - Management of symptoms such as fever and pain is essential. Antipyretics and analgesics may be administered to alleviate discomfort. However, non-steroidal anti-inflammatory drugs (NSAIDs) should be used cautiously due to the risk of bleeding[2][9].

3. Nutritional Support:
   - Providing adequate nutrition is important, especially in severe cases where patients may be unable to eat. Nutritional support can help bolster the immune response and overall recovery[2][9].

Antiviral Treatments

While there are no specific antiviral treatments approved for Marburg virus disease, several investigational therapies have shown promise:

1. Monoclonal Antibodies:
   - Treatments such as mAb114, a monoclonal antibody targeting the Marburg virus, have demonstrated efficacy in preclinical and clinical studies. These therapies aim to neutralize the virus and improve survival rates[2][9].

2. Antiviral Agents:
   - Research is ongoing into the use of antiviral drugs, such as favipiravir and remdesivir, which have shown activity against other RNA viruses. However, their effectiveness specifically against Marburg virus is still under investigation[2][9].

Experimental Treatments

1. Vaccines:
   - While there is currently no licensed vaccine for Marburg virus, several candidates are in various stages of development. Vaccination could play a crucial role in outbreak control and prevention in high-risk populations[2][9].

2. Clinical Trials:
   - Patients may have the option to participate in clinical trials for new therapies. These trials are essential for advancing treatment options and understanding the disease better[2][9].

Infection Control Measures

In addition to direct treatment, strict infection control measures are vital in managing outbreaks of Marburg virus disease. This includes:

• Isolation of Patients: Infected individuals should be isolated to prevent transmission.
