Ebola Virus Disease is caused by infection with one of the Ebola virus strains. Symptoms may include fever, headache, joint and muscle aches, weakness, diarrhea, vomiting, stomach pain, lack of appetite. In some patients, the symptoms may include: a rash, red eyes, hiccups, cough, sore throat, chest pain, difficulty breathing, difficulty swallowing, and bleeding inside and outside of the body.
Transmission is usually through direct contact with the blood, sweat, vomit, feces and other body secretions of an infected person, contact with an infected animal in the affected countries, or exposure to objects (such as needles) that have been contaminated with infected secretions. Patients with Ebola Virus Disease who are not showing symptoms are not infectious.
