Differential diagnosis

Malaria

Fever, headache, body aches, weakness and fatigue can look the same early on.

Typhoid fever

Fever, headache, weakness and abdominal or digestive symptoms can overlap.

Meningitis

Fever, severe headache, weakness and confusion can resemble Ebola symptoms.

Fever, abdominal pain and diarrhoea can resemble Ebola's gastrointestinal phase.
