caused by a bacterium called Vibrio Cholerae and usually lives in water whereas Influenza‚ more commonly known as the flu or grippe‚ is a disease cause by several different viruses so people can have it more than once. The differences between a virus and a bacterium are thus: * Bacteria are unicellular‚ Viruses have no cells. * Bacteria have DNA and RNA floating in cytoplasm‚ and a cell wall and membrane. Viruses have DNA or RNA enclosed in a protein coat. * Bacteria have Ribosomes

Ebola Virus Ebola virus (EBOV) is considered to be one of the most belligerent contagious agents and has an ability to cause highly fatal hemorrhagic fever syndrome that results in human and non-human primate’s death (NHPs) during the days of exposure. The first notification of the virus was mentioned in the Ebola River valley in Zaire for the time of an outburst in 1976. Moreover‚ the outbursts have appeared in Africa over the following 27 years‚ with death rates that differ from 50 to 90%. In
