Marburg and Crimea-Congo Hemorrhagic Fever There are over a dozen viral hemorrhagic fevers‚ and they are all divided into several different families of viruses. Some have no treatments and carry high death tolls‚ whereas others are easily treated and death easily avoided. Marburg and Crimea-Congo Hemorrhagic Fever are similar deadly viral diseases; however‚ they also have many differences as well. A hemorrhagic fever is a group of viral infections by insects‚ arachnids or rodents. (“Hemorrhagic

The Ebola Virus A virus is an ultramicroscopic infectious organism that‚ having no independent metabolic activity‚ can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid‚ either RNA or DNA‚ surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication‚ and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that

What is the Zika virus? The Zika virus comes from a daytime active Aedes mosquitoes. This virus was first identified in Uganda in 1947‚ first found in monkeys then later on found in humans in 1952. Zika had its first outbreak on an island in Yap in 2007‚ as of now we know that many countries are experiencing these same outbreaks. It’s found in mostly tropical climates which is why you can find it in Rio. This summer the olympics were held in Rio‚many of the Athletes didn’t travel and compete because

Measles Virus In the 1800’s the measles was a very dangerous disease‚ and when people who come in contact with it will die‚ if they have never been exposed to the virus before. The measles is transmitted through the air. The way that the virus is transmitted is that infected droplets are released by coughing‚ sneezing‚ and by talking. When the infected droplets that contain the measles are in the air‚ they are taken into the body through the mouth‚ nose and eyes of the potential person that

Period 7 Are Viruses Alive? For many years there have been numerous controversies over whether a virus should be classified as living or nonliving. It is believed that viruses are considered nonliving because they lack a substantial amount of qualities to be classified a form of life and they are incapable of carrying out all life processes. For example‚ some characteristics that would justify a virus being nonliving would be that they are acellular: they are not made up of cells nor do they contain
