Chapter 26, Problem 2S
Summary Introduction
To find: The greater threat to human health among antigenic drift in influenza viruses or antigenic shift in influenza virus.
Introduction: The diseases caused by viral infections are categorized into acute or persistent infections. This classification is based on how the viruses are produced rapidly and frequently and on the appearance of the associated symptoms.

Students have asked these similar questions
Compare and contrast antigenic drift and antigenic shift in influenza viruses.
c) Discuss 'antigenic drift' and 'antigenic shift' in the influenza virus and explain how such
mutations can result in an epidemic.
Why might you expect an influenza epidemic to be more severe following an antigenic shift in the virus rather than after antigenic drift?

- Explain why a different influenza vaccine is necessary every year. How is this different from the development of pandemic versions? Please include in your answer the terms antigenic shift and antigenic drift.arrow_forwardViruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sitesarrow_forwardAnswer question 35arrow_forward

What is the specific antigen on the virus that the immune system recognizes? How does it spread? What are the symptoms? What causes the seasonality? How to prevent infection?arrow_forwardFrom: "Towards a universal flu vaccine" Researchers are trying to create a universal influenza vaccine - one that can confer immunity to all, or nearly all, strains of influenza virus. The universal vaccine will target a stable antigen that is present on all influenza viruses that does not readily mutate to different forms. The target researchers are focusing on as a universal stable antigen is on the... O The H spike head.

An additional 36 cases and 15 deaths were reported outside these 3 countries. This deadly disease urged the need for extensive research on Ebola to better understand and treat the disease and prevent future outbreaks. Ebola is a - SSRNA virus. What does this mean for how it is converted into proteins? Does this virus require additional machinery to be infectious?
