What are the 6 strains of Ebola?

The six known virus species are named for the region where each was originally identified: Bundibugyo ebolavirus, Reston ebolavirus, Sudan ebolavirus, Taï Forest ebolavirus (originally Côte d’Ivoire ebolavirus), Zaire ebolavirus, and Bombali ebolavirus.

What were the proposed non-human reservoirs of Ebola?

The fifth, Reston virus, causes Ebola in non-human primates, while the sixth, Bombali virus, is not known to cause disease. Scientists believe that fruit bats or primates, such as apes and monkeys, are the natural reservoir host of Ebola viruses, although this theory is yet to be confirmed.

What are the 4 types of Ebola?

About Ebola Virus Disease There are five identified Ebola virus species, four of which are known to cause disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus).

Is Ebola virus RNA or DNA?

Abstract. The virion nucleic acid of Ebola virus consists of a single-stranded RNA with a molecular weight of approximately 4.0 x 10(6).

Why do we believe that non-human primates such as chimpanzees are not a reservoir for Ebola virus?

2. Natural reservoir. Ebola is believed to be zoonotic, however, the natural reservoir is unknown, despite extensive investigations. Non-human primates have been a source of human infection, however, they are not thought to be the reservoir as they develop severe, fatal illness when infected.

How did Ebola enter humans?

Scientists think people are initially infected with Ebola virus through contact with an infected animal, such as a fruit bat or nonhuman primate. This is called a spillover event. After that, the virus spreads from person to person, potentially affecting a large number of people.

How did Ebola go from animals to humans?

Ebola virus disease is initially introduced into human populations through contact with infected wild animals to humans and is most likely associated with hunting, collection of sick or dead wild animals and handling or consumption of uncooked bush meat.
