Question
(Pathogens evolve and cause emergent diseases)
Provide a SPECIFIC example of an emergent disease, including its most probable original source.
Solution
One specific example of an emergent disease is the Ebola virus disease. The most probable original source of the Ebola virus is believed to be fruit bats, specifically the species Hypsignathus monstrosus, Epomops franqueti, and Myonycteris torquata. These bats are considered natural Ebola virus hosts.
Ebola was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of Congo. Since then, outbreaks have appeared sporadically in Africa. The 2014–2016 outbreak in West Africa was the largest and most complex Ebola outbreak since the virus was first discovered. It also spread between countries, starting in Guinea then moving across land borders to Sierra Leone and Liberia.
The disease is severe and often fatal in humans. It can affect people and nonhuman primates (monkeys, gorillas, and chimpanzees). It is caused by an infection with one of five known Ebola virus species, four of which can cause disease in humans.
