And in this manner we transform our helper T cell into a factory that produces viral proteins and viral RNA molecules that ultimately causes the cell to lyse. And when it licenses, when it breaks open it releases many, many HIV agents that go on to essentially infect other helper T cells of our body. And in this method, what HIV does is it essentially destroys our population of helper T cells in our body and that weakens our immune system and leads to the Choired Immune Deficiency Syndrome. And because we have the acquired Immune Deficiency Syndrome we have a very, very weak immune system. Any type of infection that enters our body can essentially kill us off. And that includes the common cold.
