Your body actually has two lines of defense.  The first line of defense are positioned in cells that are in your nose, lungs and mouth.  They are able to detect foreign matter that has the ability to harm or disrupt your body.  You actually come into contact with well-known diseases on a daily basis, they are in the air you breathe yet your body’s natural form of defense is regularly able to fight off these microbes with little to no physical effects.  When your first line of defense is not strong enough to fight off the invasion, your body’s actual immune system is immediately activated and begins multiplying your white blood cells to help fight off the illness.  When your body is able to fight off an infection that it has naturally come into contact with, you are then immune to that particular strain of that virus for life.
