Ebola is actually a group of viruses that appear to be spread by bats to humans and other primates such as apes and chimpanzees. It is transmitted through bodily fluids, including blood, poop, vomit, urine, breast milk, and semen. It can enter a person's body through cuts in the skin, or through mucous membranes—tissues that line the eyes, nose, mouth, urethra, and vagina. At first, Ebola may seem like the common flu. Symptoms include exhaustion, aches and pains, vision problems, and stomach pain. But in most patients, Ebola quickly escalates to a full-blown hemorrhagic fever, which leads to bleeding, organ failure, and in many cases, death.
