Ebola disease - including symptoms, treatment and prevention

If you get unwell within 21 days of arriving in Australia from the Democratic Republic of the Congo or Uganda:

  • call your healthcare professional immediately — tell them about your symptoms and travel history.
  • do not visit a clinic or hospital in person without calling ahead — they might take extra steps to protect others.
  • dial 000 in an emergency and tell them about your symptoms and travel history.

Ebola disease is caused by an Ebola virus, of which there are five species. Ebola disease is also known as Ebola, and was previously called Ebola haemorrhagic fever.

Ebola disease is a type of viral haemorrhagic fever (VHF), which are life threatening infections whose symptoms can include fever and bleeding.

Ebola disease is a notifiable condition1

Outbreaks of Ebola disease in humans have occurred only in Africa, specifically in, the Democratic Republic of Congo, Gabon, the Sudan, South Sudan, Uganda, Guinea, Sierra Leone, Liberia and Nigeria. There has never been a case in Australia.

How Ebola disease is spread

Many VHF viruses are found naturally amongst wild animals, such as bats, rodents (for example, rats and mice), monkeys and apes. Occasionally these viruses break through into the human population and cause outbreaks, then usually disappear for many years.

The natural animal host of Ebola virus is unknown. It is likely the first patient in a cluster or outbreak becomes infected with Ebola virus through contact with an infected animal.

Ebola disease can be transmitted from person to person via:

  • contact with blood or body fluids (for example, urine, saliva, faeces and vomit) from an infected person (living or deceased)
  • contact with an area contaminated with blood or body fluids of an infected person
  • sexual transmission.

Signs and symptoms of Ebola disease

Initial symptoms are flu-like and may include:

  • sudden onset of fever
  • muscle aches and pains
  • tiredness
  • headaches.

Illness then progresses with symptoms such as:

  • diarrhoea and vomiting
  • headaches and confusion
  • rash
  • sore throat and cough
  • extreme tiredness and collapse.

Some people go on to develop bleeding problems, multi-organ failure and death. Bleeding problems may include bleeding from the nose or gums, vomiting or coughing blood, bruising, rashes and internal bleeding.

The death rate of Ebola  disease depends on the species. For Zaire species of Ebola virus it is estimated to be between 50% and 90%.

Diagnosis of Ebola disease

Cases are diagnosed by PCR on a blood specimen.

Incubation period

(time between becoming infected and developing symptoms)

From 2 to 21 days, most commonly 8 to 10 days.

Infectious period

(time during which an infected person can infect others)

People are not infectious until the onset of symptoms. People are infectious as long as blood and secretions contain virus.

Treatment for Ebola disease

People with any symptoms of Ebola disease who have been in contact with someone with Ebola disease (or their blood or body fluids) should go to a hospital, preferably by ambulance, (and tell the ambulance and hospital staff of their exposure) to get treatment and avoid spreading the disease to others.

Prevention of Ebola virus disease

  • Individuals with suspected or confirmed Ebola disease need to be isolated and excluded from childcare, preschool, school and work until cleared to return by a doctor
  • health care workers who care for a patient with suspected or confirmed Ebola disease should use hand hygiene and appropriate personal protective equipment
  • for at least several months after recovery and until advised otherwise by a doctor, males who have had Ebola  disease should use a condom when engaging in sexual intercourse
  • those who visit an area where Ebola disease occurs should not eat raw or undercooked ‘bush meat’ including ape, monkey or bat.
  • People should not have contact (or eat) with blood, meat or body fluids of animals which show signs of Ebola disease.
