Flu virus: an example of variability

We will learn about the viral structure of influenza viruses and their replicative cycle. We will understand about changes and mutations are produced.

Influenza viruses are really interesting!

In the complex process of replication, viruses may make mistakes and progeny viruses are not the same as the parental viruses. After watching the video you will understand how and why these new viruses may potentially produce epidemics and pandemics.

Have your say

Now that you know about influenza viruses, you can compare them with the viruses studied in previous weeks. What differences in structure, genome and replication have you seen? Can you explain the differences between antigenic drift and antigenic shift? Discuss your opinions in the Comments with other learners.
