PRESENTATION OUTLINE
PHASE ONE
You go to the movie theatre with some friends. After you sit down, a guy sits behind you. Little do you know, he has the flu. He is continuously coughing and sneezing throughout the movie until one of his sneezes launches through the air and is now waiting to be inhaled so it can find a host.

PHASE TWO
The virus finds it's host, which, in this case, is you. The virus needs a warm area to survive, and it finds it's nearly ideal habitat in your nose. When the guy sneezed, the virus was launched through the air and within moments, you inhaled it and are now on your way to becoming infected. The virus is currently in your nose waiting to find your throat so it can further the damage.

PHASE THREE
This phase is when infiltration takes place. Although the virus is already in your nose, it needs an extra push to get it down the nasal passage where it can arrive and proceed with replication. This push happens when you inhale. After being caught up in your nose hairs (cilia) and mucus, an eventual sniff causes the virus to launch down your nasal passage. This is when the symptoms start, generally beginning in a fever.

PHASE FOUR
Now that the virus is in your throat it must find a suitable throat cell to try to gain access to. After finding one, the virus disguises itself as a harmless protein and the cell unknowingly allows the virus T
inside.

PHASE FIVE
Since the virus now has control of the cell, it begins the process of replication. The replication causes thousands of virus cells to be created, furthering your sickness. Eventually, the cell bursts.
