Overview
Ebola causes a variety of symptoms which may include fever, chills vomiting, diarrhea, generalized pain or malaise, and sometimes internal and external bleeding, that follow an incubation period of 2-21 days. These symptoms are common to all species of Ebola virus, but the different species may present with differences in the severity of symptoms.
History
Ebola hemorrhagic fever should be suspected in patients with acute febrile illness, hemorrhagic symptoms, and a history of travel to an endemic area. The history of a patient with suspected Ebola virus infection requires a clear assessment of exposure. Travel to endemic countries particularly in West Africa including Sierra Leone, Liberia, Guinea, and Nigeria is important to note. Other exposure to Ebola virus including direct contact, or exposure to blood or body fluids of infected patients, processing blood or body fluids of a patient with suspected or confirmed Ebola virus infection, and contact with a dead body without appropriate personal protective equipment in an endemic country. Other important questions include: duration of fever, systemic manifestations, and appearance of any hemorrhagic symptoms.
Early Symptoms
Incubation period ranges from 2 to 21 days. The majority of symptomatic patients have fatal outcomes, often initially develop initially flu-like or malaria-like symptoms before multisystem organ failure and bleeding diasthesis take place.
Constitutional symptoms
- Fever and chills are the most common presenting features of Ebola virus infection
- Headache
Skin
- Characteristic maculopapular, non-pruritic rash with erythema. Skin rash typically appears within 5-7 days of disease onset and has a centripetal distribution.
- Desquamation
Musculoskeletal
- Arthralgia
- Myalgia
Respiratory
Gastrointestinal
- Abdominal pain
- Nausea
- Vomiting
- Diarrhea, which may be bloody even in the early phase of the disease
Ophthalmological
Hemorrhagic disease
- Epistaxis
- Mucosal bleeding
Late Symptoms
Respiratory
- Dyspnea
Cardiovascular
- Chest pain
Gastrointestinal
- Abdominal pain that may be related to pancreatitis, intestinal wall swelling, or mesenteric lymphadenopathy
- Abdominal distention
Neurological
- Hiccups, which classically herald worse outcomes and death
- Confusion
- Tinnitus
- Hearing loss
- Dysphagia
- Convulsions
- Coma
Hemorrhagic Disease
- Jaundice
- Petechiae
- Ecchymoses
- Epistaxis
- Mucosal bleeding
- Hematemesis
- Melena
- Hematuria
- Vaginal bleeding
- Uncontrolled bleeding from venipuncture sites
- Hemorrhagic shock
