Ebola began in fruit bats native to Sub-Saharan Africa. As the years progressed, the virus mutated to be able to infect other mammals, like primates. This genetic variation allowed it to survive more easily, therefore leading the primate strains to produce offspring. (Reid, 2016)
Currently, there is no cure for Ebola. Rather than treating the disease itself, which may lead to Ebola becoming more resistant to medicine, scientists are developing treatments for individual symptoms. (CDC, 2015)
Though Ebola is not particularly contagious, it can be deadly. In 2014, a man died of Ebola in Dallas, which resulted in a massive social freakout.
