Scientists do not know where Ebola virus comes from. However, based on the nature of similar viruses, they believe the virus is animal-borne, with bats or nonhuman primates (chimpanzees, apes, monkeys, etc.) being the most likely source.

Who found cure for Ebola?

A phase one trial started in December 2014. The drug was effective in Ebola-infected monkeys. Brincidofovir, an antiviral drug, has been granted an emergency FDA approval as an investigational new drug for the treatment of Ebola after it was found to be effective against Ebola virus in in vitro tests.

Why is Ebola only in Africa?

Most theories involve the country’s large forested areas, and the possibility that infected fruit bats—widely believed to be the primary reservoir animal for the disease—are common in the affected areas.

How did Ebola jump to humans?

Is Ebola a biological weapon?

The virus is already so capable of spreading from person to person via contact with bodily fluids that in its natural state it could do some serious damage. “Ebola is a very lethal pathogenic virus,” says virologist Robert Garry of Tulane University. “It’s basically weaponizing itself.”
