Causes and Symptoms of Ebola


The virus belongs to the viral family Filoviridae. The origin of the virus is likely from African fruit bats. Since the virus is transmitted from animals to humans, the virus is also called as zootic virus. The virus can also be transmitted from one human to another.
The following animals can transmit the Ebola virus:
  • Chimpanzees
  • Forest antelopes
  • Gorillas
  • Monkeys
  • Porcupines
Since people may come in contact with these animals, the virus can get transmitted from the blood or any body fluid of these animals. Point to be considered is that the virus gets transmitted only by coming in direct contact with the body fluids of someone who has the virus and not by air or touch alone.
Bodily fluids that may carry the virus may be through:
  • blood
  • diarrhea
  • breast milk
  • feces
  • saliva
  • semen
  • sweat
  • urine
  • vomit
Virus transmission can take place through eyes, nose, broken skin, mouth or sexual contact. Workers working in healthcare centers often deal with bodily fluids and blood and hence are at a high risk for getting the infection
As per the Centers for Disease Control and Prevention (CDC), the symptoms of Ebola typically appear within 8-10 days after being exposed. However, it may take 2 to 21 days for the symptoms to show up. Initially, Ebola can feel like a flu. First and the most noticeable symptom of Ebola is extreme fatigue. Other symptoms include:
  • High fever
  • Headache
  • Joint and muscle aches
  • Sore throat
  • Weakness
  • Stomach Pain
  • Lack of appetite
  • Unexplained bleeding or bruising
  • Diarrhea
  • Vomiting

Diagnosis of Ebola

It is very difficult to diagnose Ebola in a person who has been infected by the virus for only a few days. The reason is that the early symptoms like fever are non-specific and are often observed in patients with more common diseases like malaria and typhoid fever. However, once a person has been diagnosed with early symptoms of Ebola, the person should be isolated and it is very important to notify the public health authorities about the case. If a person has come in direct contact with: Bodily fluids or blood of an Ebola infected person who has died Items that were handled by an Ebola infected person and are contaminated with the blood or body fluids of the sick person Semen from a man who has just recovered from Ebola To confirm infection, samples from the patient can be taken and tested. For the symptoms to reach detectable levels, it may take up to three days after the onset of symptoms. Only after the onset of symptoms, most prominent being fever, is the Ebola virus detec...

Ebola virus Disease Progression

Ebola is a disease caused by the Ebola virus. Ebola virus belongs to the family Filoviridae . Filoviridae is the only virus family about which scientists know very less. Knowledge about the pathogenesis, the diseases caused by this virus family and the detailed virology is still very less. The recent epidemics have provided a considerable amount of understanding about the filoviruses. The first encounter of biomedical science with virus family Filoviridae took place in 1967 when Marburg virus appeared. Similar course of events were presaged by this virus for Ebola virus. On an average, the incubation period for Ebola Virus disease in humans lasts for 5-9 days though the overall incubation period of Ebola Virus disease in humans ranges from 2 to 21 days. There are three distinct phases in the course of the disease: Generalization phase, early organ phase, late organ phase or convalescence phase depending upon the result of the infection. Generalization phase : This phase begins wit...

Treatment and recovery from ebola

Ebola virus causes Ebola virus disease (EVD), also known as Ebola haemorrhagic fever or Ebola. The disease caused by the virus is often fatal. The virus gets spread by direct contact with bodily fluids or blood of an infected person or infected animal. The symptoms of the disease are not very clear and the disease initially feels like flu. The symptoms include stomach pain, muscle aches, vomit, diarrhea, unexplained bleeding or bruising and fatigue. As of now, there is no known medication or vaccine which is effective. The scientists are still in the early stages of understanding how the infection caused by Ebola virus can be treated. There are a number of experimental treatments that are being considered for use in cases of Ebola outbreaks. The experimental treatments are under clinical trials. As there is no cure for Ebola and research is still going on for finding one, the experimental treatment carried out by the doctors include a serum that is said to destroy the infected cell...
