EBOLA (EVD)


What is it?

Ebola virus disease (EVD) is a severe disease that causes haemorrhagic fever in humans and animals. Diseases that cause haemorrhagic fevers, such as Ebola, are often fatal as they affect the body's vascular system (how blood moves through the body). This can lead to significant internal bleeding and organ failure.
The current outbreak in West Africa, (first cases notified in March 2014), is the largest and most complex Ebola outbreak since the Ebola virus was first discovered in 1976. There have been more cases and deaths in this outbreak than all others combined.

As long as precautions are taken, there is low risk of contracting EVD in a country where the disease is present. For the most current updates on the outbreak in West Africa, go to World Health Organization’s website at, http://www.who.int/en/.

How is it spread?

The Ebola virus can enter the body through broken skin or unprotected mucous membranes (e.g., mouth, eyes, nose). It can spread through contact with blood or body fluids (feces, saliva, urine, vomit, and semen) or tissues of infected persons, contact with medical equipment, such as needles that have been contaminated with infected blood or body fluids, and contact with infected animals.

Exposure can occur in health care settings when staff do not wear appropriate protective equipment such as masks, eye protection gowns and gloves, or do not follow appropriate infection control practices. Ebola is not spread through the air or by water or food.

What do I look for?

Symptoms usually occur anywhere from 2 to 21 days after exposure. Initial symptoms include sore throat, fever, chills, headache, muscle pain, weakness, and stomach pains. Additional symptoms include rash, nausea, vomiting, diarrhea, and haemorrhaging (bleeding from inside and outside the body).

What to do if you become ill?

How is it treated?

There is currently no specific licensed treatment or vaccine for EVD. Patients are treated for their symptoms.
