Part 4 - Virions, Prions, and Viruses

Learning Target:  I can compare and contrast viroids, prions, and viruses. Step 1: Use a sampling of the Web sites below to learn about prions, the diseases they cause, and the steps that the United States has taken to help prevent the spread of prion-related diseases. Take notes to help you remember what you learn. The united states setup an organization called The National Prion Disease Pathology Surveillance Center . Step 2: Use this information to evaluate whether we are safe from the prion that has been linked to prion diseases found in animals. Describe how you would propose protecting the public from prion diseases. Prion diseases are rare but most of the time fatal. Step 3: Prions are unusual disease agents. Explain exactly how they cause disease? What can be done to stop the spread of prion diseases? What are the types of prion diseases found in animals and in humans?  How are they similar and different?
