Ebola Virus Infection is a rare but deadly virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes levels of blood-clotting cells to drop. This leads to severe, uncontrollable bleeding. The disease, also known as Ebola hemorrhagic fever or Ebola virus, kills up to 90% of people who are infected. Although movies and books describe major outbreaks of Ebola-like disease in the U.S., they\'re just fiction. So far serious Ebola cases have only shown up in Central and West Africa. It has strong safety measures in place for people who have Ebola. Ebola can spread from country to country when people travel. So it is possible for it to reach the U.S. if an infected person travels here. But there are ways to prevent people from coming to U.S. airports with the disease. Airline crews are trained to spot the symptoms of Ebola in passengers flying from places where the virus is found. Crews are told to quarantine anyone who looks infected. Ebola isnít as contagious as more common viruses like colds, influenza, or measles. It spreads to people by contact with the skin or bodily fluids of an infected animal, like a monkey, chimp, or fruit bat. Then it moves from person to person the same way. Those who care for a sick person or bury someone who has died from the disease often get it. Other ways to get Ebola include touching contaminated needles or surfaces. Infection of Ebola can be spread from air, water, or food. A person who has Ebola but has no symptoms canít spread the disease, either. Early on, Ebola can feel like the flu or other illnesses. Symptoms show up 2 to 21 days after infection and usually include: High fever, Headache, Joint and muscle aches, Sore throat, Weakness, Stomach pain, Lack of appetite, Blood vomiting. As the disease gets worse, it causes bleeding inside the body, as well as from the eyes, ears, and nose. Some people will vomit or cough up blood, have bloody diarrhea and get a rash. Sometimes it\'s hard to tell if a person has Ebola from the symptoms alone. Doctors may test to rule out other diseases like cholera or malaria. Tests of blood and tissues also can diagnose Ebola.
