Summary Introduction
To determine:
The reason that the antigenic shift event in the Influenza virus can lead to a catastrophic pandemic.
Introduction:
A virus is a smallest agent that can cause infection. The virus replicates inside the living cells of the host body. Influenza, commonly known as flu, is a respiratory illness caused by a virus. Symptoms can be mild to severe. Antigenic shift events are the minute changes that occur in the genes of the Influenza virus.
