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.

Which of the following statements concerning antigenic drift in influenza viruses is correct?
A-It results in major antigenic changes
B-It affects predominantly the matrix protein
C-It is exhibited by only influenza A viruses
D-It is due to frame shift mutations in viral genes
E-It results in new sub types over time
Compare and contrast antigenic drift and antigenic shift in influenza viruses.
