The Hidden Killers: Deadly Viruses
Military Uses


The Marburg virus and the Ebola virus are rather nasty viruses. One might kill an infected person and one will kill. There is no known cure for either. The information is interesting and brief. Students will read and then compare and contrast the two viruses. Printing out the directions will be helpful. This is a GED activity.

    • What is the fatality rate of each virus?
    • In what country did each virus originally appear?
    • After what was each virus named?
    • To what kind of exposure was each virus linked?
    • How many people were infected with each virus?
    • How many died?
    • What is the shape of each virus?
    • How are these viruses transmitted?
    • What are the symptoms for each virus?
    • What is the cure for each virus?
    • What is the treatment for each virus?
  • Write a short essay comparing and contrasting the Marburg virus and the Ebola virus.
    • Introduce both viruses. Use the lists you made from the questions. The reader needs to know which virus is which. Label them, by name, most of the time to be clear. Do not be concerned with the number of words this time. Just write how the Marburg and Ebola viruses are the same and how they are different. The information is already in the lists. Just write the information in sentences and paragraphs. You will do a great job!

Now everyone is prepared for pulling everything together. Watch Outbreak.
