Ebola spreads through direct contact with infected bodily fluids or tissue.
Even after a person has died, the virus persists.
At the time of death, a patient can have one billion copies of the virus in one cubic centimeter of blood. In comparison, HIV, a similar virus, has the same rate at the time of death. But unlike HIV, which only infects two types of immune cells, Ebola first infects white blood cells that disable the body’s ability to destroy foreign substances, then seizes nearly every cell type.
