INfluenza+Notes+BH

September 26, 2007

the virus locks on to the proteins of a cell and the virus injects itself into the cell.

The flu virus infects the cells in your lungs

there are protiens on the surface of the lung cell.

lock and key analogy. (virus has a key that only fits that cell and the cell only has a lock)

the cell copies the genetic material which spreads the virus. (it ends up killing the cells)

the antogenes will attack the cells that are effected.

3 reasons to get a flu vaccination

1. Prevents influenza related death--> 36,000 people die from flu every year. most are 65 or older

2. prevent severe illness. --> puts about 200,000 people in the hospital every year.

3. protects other people. --> get vaccinated if you live with or care for others that are at high risk at getting the flu.

swine pigs--> have the flu virus ( they can get the virus)

influenza A virus--> ducks, chickens, whales, pigs, horses, and whales

influenza B virus--> is fond in humans

most don't cause disease in humans.
