Ebola is a rare but severe and often fatal viral disease that affects the blood vessels and causes severe inflammation and tissue damage throughout the body. It is characterised by initial symptoms such as fever, fatigue, muscle pain, and headache, followed by gastrointestinal issues and impaired kidney and liver functions. The high fever and achy muscles associated with Ebola can be attributed to the virus's ability to cause severe inflammation and damage throughout the body, including to blood vessels, which can result in internal bleeding.

Ebola is a viral haemorrhagic fever that damages blood vessels
Ebola is a viral hemorrhagic fever that damages blood vessels. It is a rare but severe and often fatal disease that affects blood vessels and can cause severe inflammation and tissue damage throughout the body. Ebola is caused by a group of viruses known as ebolaviruses, which are highly contagious and lethal. The disease gets its name from the Ebola River in the Democratic Republic of Congo (formerly Zaire), where the virus was first discovered in 1976.
Ebola symptoms typically start between two and 21 days after infection, with the first symptoms usually being fever, sore throat, muscle pain, and headaches. These initial symptoms are often followed by gastrointestinal issues such as vomiting and diarrhoea, as well as decreased liver and kidney function. Some patients may also experience internal and external bleeding, including blood in vomit and faeces, bleeding from the nose, gums, and vagina, and oozing from venipuncture sites.
The high fever associated with Ebola is one of the most common initial symptoms of the disease. Fever is characterised by an elevated body temperature, which can be a response to infection or other ailments. In the case of Ebola, the fever is caused by the virus infecting and damaging blood vessels, leading to severe inflammation and tissue damage. This damage can disrupt the body's ability to regulate temperature, resulting in a raised body temperature or fever.
The achy muscles associated with Ebola are also a common early symptom of the disease. This muscle pain, or myalgia, is likely caused by the same mechanisms that lead to severe inflammation and tissue damage throughout the body. The virus damages blood vessels and surrounding tissues, resulting in pain and discomfort in the affected areas. This pain can be widespread, affecting multiple muscle groups, and can be quite debilitating for those infected.
The fatality rate of Ebola has varied from 25% to 90% in past outbreaks, with an average fatality rate of around 50%. The high fever and achy muscles caused by Ebola are not directly responsible for these fatalities. However, they are often the first warning signs of the disease, prompting individuals to seek medical attention. Early detection and treatment of Ebola are crucial for improving survival rates.

The disease causes severe inflammation and tissue damage throughout the body
Ebola is a serious and potentially fatal disease that affects blood vessels and causes severe inflammation and tissue damage throughout the body. It is a viral haemorrhagic fever that damages the blood vessels and causes problems with the clotting system, leading to internal bleeding. This is because the virus causes blood to leak from small blood vessels.
The symptoms of Ebola include fever, fatigue, malaise, muscle pain, headache, and sore throat. These are followed by gastrointestinal issues such as vomiting, diarrhoea, and abdominal pain. The disease can also cause a rash and symptoms of impaired kidney and liver function. Some patients may experience internal and external bleeding, including blood in vomit and faeces, bleeding from the nose, gums, and vagina, and bleeding at the sites of needle punctures.
The early symptoms of Ebola are non-specific and can be easily confused with other illnesses such as malaria, influenza, typhoid fever, or meningitis. The non-specific symptoms are known as "dry" symptoms and include fever, weakness, and fatigue. After four to five days, patients can progress to "wet" symptoms, which include diarrhoea and vomiting.
The high fever and achy muscles associated with Ebola are caused by the severe inflammation and tissue damage that the disease inflicts throughout the body. The fever is a common initial symptom, and muscle pain is also an early symptom. The virus can cause severe pain and discomfort, impacting the patient's quality of life and ability to perform daily tasks.
The fatality rate of Ebola is high, ranging from 25% to 90% in past outbreaks, with an average mortality rate of around 50%. Early treatment and supportive care, including rehydration and symptom management, are crucial for improving survival rates. Ebola is spread through direct contact with bodily fluids or contaminated objects and can remain in bodily fluids like semen or breast milk for several weeks to months after recovery.

Symptoms of Ebola include fever, muscle pain, headache, and sore throat
Ebola is a rare but severe and often fatal viral illness in humans. It is caused by viruses that belong to the Orthoebolavirus genus of the filoviridae family. The disease gets its name from the Ebola River in what is now the Democratic Republic of Congo, where the virus was first discovered in 1976.
In addition to the symptoms mentioned above, Ebola can also cause red eyes, rash, hiccups, seizures, and neurologic symptoms such as confusion and aggression. Bleeding is a less common symptom, occurring in less than 50% of cases, and usually appears later in the disease. However, it can be severe and even fatal, as Ebola can cause problems with the clotting system of the body, leading to internal bleeding.
Due to its nonspecific early symptoms, Ebola can be difficult to diagnose and may be confused with other illnesses such as malaria, typhoid fever, meningitis, cholera, or dengue fever. If you believe you may have been exposed to Ebola and are experiencing symptoms, it is important to seek immediate medical attention.

Ebola is transmitted through direct contact with bodily fluids
Ebola is a severe, often fatal viral haemorrhagic fever that damages blood vessels. It is caused by viruses that belong to the Orthoebolavirus genus of the filoviridae family. The disease was first discovered in 1976 in two simultaneous outbreaks in what is now South Sudan and the Democratic Republic of Congo. The latter occurred near the Ebola River, hence the name.
Bodily fluids that may contain Ebola viruses include saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine, and semen. The World Health Organization (WHO) states that only people who are very sick are able to spread Ebola through saliva, and there have been no reported cases of transmission through sweat. Most people spread the virus through blood, faeces, and vomit.
It is important to note that Ebola cannot be transmitted through casual contact, food, water, or air. The virus enters the body through specific entry points, such as the nose, mouth, eyes, open wounds, cuts, and abrasions. Therefore, it is crucial to avoid direct contact with the bodily fluids of infected individuals and to maintain proper hygiene practices to prevent the spread of the disease.
Healthcare providers, caregivers, and family members who come into close contact with infected individuals are at the highest risk of contracting Ebola. It is recommended that they wear proper protective equipment, practice good hand hygiene, and take the necessary precautions to minimise the risk of exposure to bodily fluids.

Treatment for Ebola is supportive and focuses on treating symptoms
Ebola is a rare but severe and often fatal illness that affects blood vessels. The symptoms of Ebola include fever, fatigue, malaise, muscle pain, headache, and sore throat. These are followed by vomiting, diarrhoea, abdominal pain, rash, and symptoms of impaired kidney and liver functions.
Early intensive supportive care with rehydration and the treatment of symptoms improves survival rates considerably. Seeking early care can be lifesaving. Approved vaccines and treatments are only available for one of the viruses (the Ebola virus) and are under development for the others. Outbreak control relies on a package of interventions, including intensive supportive care of patients, infection prevention and control, disease surveillance, and contact tracing.

Frequently asked questions
Ebola is a viral hemorrhagic fever that damages blood vessels and causes severe inflammation and tissue damage throughout the body. The virus can lead to problems with the clotting system, resulting in internal bleeding as blood leaks from small blood vessels. The fever and muscle pain are caused by the body's immune response to the virus, as it tries to fight off the infection.
Early symptoms of Ebola are non-specific and flu-like, including fever, fatigue, muscle and joint pain, headache, sore throat, weakness, and loss of appetite. These typically appear 2-21 days after exposure to the virus, with an average onset of 8-10 days.
Ebola is transmitted through direct contact with the bodily fluids of infected humans or other animals, such as blood, saliva, sweat, urine, or semen. It can also be spread by touching contaminated objects or surfaces.
Ebola is a severe and often fatal disease, with an average case fatality rate of around 50%. In past outbreaks, fatality rates have ranged from 25% to 90%. Death usually occurs between 6 and 16 days after the first symptoms appear.
There is no approved cure for Ebola as of 2019. Treatment focuses on providing intensive supportive care, including rehydration and management of symptoms, to improve survival rates. Two monoclonal antibody treatments, Ebanga and Inmazeb, have shown improved outcomes. A vaccine for Ebola was approved by the FDA in December 2019.
