Ebola Hemorrhagic Fever (EHF) should be suspected if one or more of the following case definitions are met.
Case definition 1 – both of the following:
(1) presence of fever
(2) presence of bleeding (from gums, from nose, from gastrointestinal tract, purpura, bloody vomitus, hemorrhagic conjunctivitis)
Case definition 2 – both of the following:
(1) presence of fever with or without bleeding
(2) contact with a person with EHF
Case definition 3 – both of the following:
(2) 3 or more of the following:
(3c) loss of appetite (anorexia)
(3e) severe fatigue or weakness
(3f) abdominal pain
(3g) generalized muscle or joint pain
(3h) difficulty swallowing
(3i) difficulty breathing
Case definition 4:
(1) an unexplained death in an area with cases of EHF
• Case definition 3 appears to be nonspecific for EHF.
• It is important to exclude alternative diagnoses and infections. For example, radiation poisoning could present with many of these findings.
• All of these definitions are presumptive. Definitive testing should be performed to establish the diagnosis.
