In this lecture, Professor Zach Murphy breaks down Influenza with a clear, high-yield approach focused on recognition, diagnosis, and management. This video builds a practical framework for understanding how influenza infects the respiratory tract and why it can progress from a mild illness to severe disease.
We begin with virology and transmission, including the segmented RNA genome and the roles of hemagglutinin and neuraminidase. Zach explains the differences between antigenic drift and antigenic shift, and how these mechanisms drive seasonal epidemics and pandemics.
Next, the lecture covers clinical presentation and risk stratification. You will learn to recognize classic symptoms and identify high-risk patients who are more likely to develop complications. The pathophysiology of respiratory epithelial damage and its role in disease severity are also emphasized.
The session then focuses on complications and diagnosis, including primary viral pneumonia and secondary bacterial pneumonia, along with how to differentiate them clinically and with imaging.
Finally, Zach reviews treatment and prevention, including when to initiate antivirals and key vaccination principles.
