What is Ebola?
• Q: What is Ebola?
• A: Ebola virus is the cause of a
viral haemorrhagic fever disease.
Symptoms include: fever,
headache, joint and muscle aches,
weakness, diarrhoea, vomiting,
stomach pain, lack of appetite,
and abnormal bleeding.
Symptoms may appear anywhere
from 2 to 21 days after exposure
to Ebola virus although 8-10 days
is most common.
Transmission
•
Q: How is Ebola transmitted?
•
A: Ebola is transmitted through direct contact with
–
–
–
–
Blood
Secretions
Organs
Other bodily fluids. And
Through indirect contact with;
–
Environments contaminated with such fluid
• Transmission through sexual contact may be possible for up to 7 weeks after clinical recovery.
•
Q: Can I get Ebola from a person who is infected but doesn’t have any symptoms?
•
A: No. Individuals who are not symptomatic are not contagious. In order for the virus to be transmitted, an individual
would have to have direct contact with an individual who is experiencing symptoms.
Signs and Symptoms to watch for
• Sudden onset of symptoms
–
–
–
–
–
Influenza like illness
Fever > 38°C
Myalgia
Fatigue
Headache
• 2nd stage
–
–
–
–
GIT – Vomiting, diarrhoea
Neuro – headaches, confusion
Vascular cutaneous – maculopapular rash
Respiratory – sore throat, cough
• Additionally
– Septic shock-like syndrome
– Multi organ failure
– Profuse internal and external bleeding
Questions for Triage
Patients presenting to ED with fever >=38°C
1.
Have you been travelling outside Australia in the last 21 days?
2.
If YES, did you travel to Africa?
3.
If YES, did you visit any of the following countries
–

IF YES then take IMMEDIATE ACTION!

2)
Admit patient immediately to ISOLATION (Resus 3 – negative pressure) and commence Contact &
Droplet precautions as designated
3)

Part 2
5.
Isolate Ambulance entrance - Hospital to go on Bypass (is this necessary at TNH??)
6.
Transfer to RMH as soon as safe to do so.
7.
ONLY if clinically indicated and ONLY after notification to Department of Health should Pathology
tests be taken.
8.
DO NOT under any circumstances use a Blood Gas Machine for pathology testing
General principles for managing EVD
1)
If patient’s condition requires immediate intervention to preserve life then manage in isolation in
Emergency with an aim of stabilisation for transport.
2)
If the patient is clinically stable arrange immediate transfer to Royal Melbourne Hospital. (we do not
have appropriate Critical Care isolation rooms)
