Consider the following statements about ebola virus -
1. Ebola virus and its genus were both originally named for Zaire (now the Democratic Republic of Congo), the country where it was first described,and was at first suspected to be a new "strain" of the closely related Marburg virus.
2. The virus was renamed "Ebola virus" in 2010 to avoid confusion. Ebola virus is the single member of the species Zaire ebolavirus, which is the type species for the genus Ebolavirus, family Filoviridae, order Mononegavirales.
3. The natural reservoir of Ebola virus is believed to be bats, particularly fruit bats,and it is primarily transmitted between humans and from animals to humans through body fluids.
4. The EBOV genome is a single-stranded RNA approximately 19,000 nucleotides long. It encodes seven structural proteins: nucleoprotein (NP), polymerase cofactor (VP35), (VP40), GP, transcription activator (VP30), VP24, and RNA-dependent RNA polymerase (L).
