Ebola virus disease (EVD), commonly known as Ebola hemorrhagic fever, is one of the deadliest viral infections known to humankind. With its origins traced back to 1976 in Sudan and the Democratic Republic of Congo, the virus spreads swiftly, causing severe internal bleeding, organ failure, and, in many cases, death. Although Ebola outbreaks have been largely confined to sub-Saharan Africa, the globalized world has made disease surveillance and rapid response critical in preventing widespread transmission.

What are the symptoms of Ebola virus?

Ebola virus symptoms typically appear within two to 21 days of exposure, starting with mild signs and progressing to more severe conditions. Early symptoms include fever, fatigue, muscle pain, and headaches, which can easily be mistaken for other illnesses. As the disease advances, individuals may experience vomiting, diarrhoea, and internal or external bleeding. In severe cases, multi-organ failure and shock may occur, often leading to fatality if left untreated. Prompt medical attention can help manage symptoms and improve survival rates.

How is the Ebola virus transmitted?

Ebola virus is primarily transmitted through direct contact with infected bodily fluids such as blood, saliva, urine, or sweat. This includes contact with contaminated surfaces, needles, or medical equipment. Human-to-human transmission occurs when broken skin or mucous membranes come into contact with the virus. Additionally, Ebola can spread through handling or consumption of infected animals like bats or primates, which are believed to be natural hosts of the virus. Airborne transmission has not been documented, but strict hygiene and protective measures are essential to contain outbreaks.

What are the main causes of Ebola virus?

Ebola outbreaks are triggered by exposure to the virus, often through human contact with infected wildlife or contaminated environments. The virus then spreads quickly in human populations, particularly in settings with limited medical resources.

  • Contact with infected wildlifeHandling or consuming infected animals, such as fruit bats or primates, can lead to the initial transmission of the virus to humans.
  • Human-to-human transmissionDirect exposure to bodily fluids of an infected person, including blood, vomit, or saliva, facilitates the rapid spread of the virus.
  • Poor hygiene and sanitationLack of proper hygiene practices, especially in healthcare settings, contributes to the spread of Ebola through contaminated surfaces or medical equipment.
  • Cultural practicesTraditional burial rituals involving physical contact with deceased individuals can also result in the transmission of the virus.

Understanding Ebola virus treatments and vaccines

Managing Ebola virus disease relies on supportive care and experimental treatments, as there is no definitive cure. Treatments focus on maintaining hydration, stabilising vital signs, and addressing complications like infections or organ failure. Antiviral medications, such as Remdesivir, have shown promise in reducing the severity of symptoms in some cases.

  • Supportive careRehydration with oral or intravenous fluids and oxygen therapy is crucial for improving patient outcomes.
  • Antiviral drugsExperimental drugs and therapies are being developed to target the Ebola virus and enhance recovery rates.
  • VaccinesPreventative vaccines, such as rVSV-ZEBOV, have been introduced to protect at-risk populations and healthcare workers in regions prone to outbreaks.
  • Experimental antibody therapiesMonoclonal antibodies, such as Inmazeb and Ebanga, have been approved for emergency use in treating Ebola patients, offering new hope in managing the disease.

By focusing on early diagnosis, effective treatments, and widespread vaccination, significant progress can be made in controlling and ultimately eradicating Ebola outbreaks.

Innovations in antiviral drugs and antibody therapies have significantly improved disease outcomes. But access to cutting-edge medical treatments can be expensive. Ensure your health insurance covers advanced treatments so you’re protected against evolving health threats.

Prevention tips for avoiding Ebola virus

Preventing the spread of the Ebola virus requires a combination of personal hygiene, safe practices, and community awareness. Effective prevention measures are especially crucial during an Ebola outbreak, as the virus is highly infectious and spreads rapidly through direct contact with infected individuals or contaminated environments. By following recommended precautions, individuals can minimise the risk of transmission and protect themselves and their communities.

  1. Practice proper hygieneWash your hands regularly with soap and water or use an alcohol-based hand sanitiser, especially after coming into contact with others or handling potentially contaminated items.
  2. Avoid contact with bodily fluidsRefrain from direct contact with blood, saliva, urine, sweat, or other bodily fluids of infected individuals.
  3. Handle animals safelyAvoid contact with bats, primates, and other wildlife, as they are natural hosts of the Ebola virus, particularly in outbreak-prone regions.
  4. Follow safe burial practicesAvoid direct contact with the bodies of individuals who have died from Ebola, and adhere to guidelines set by health authorities for burial procedures.
  5. Use protective equipmentHealthcare workers and caregivers should wear personal protective equipment (PPE), such as gloves, masks, and gowns, when treating or caring for Ebola patients.
