WHY HIV AIDS IS VERY DANGEROUS.

First of all we have understand about Hiv&Aids,Aids [acquird immune deficiency syndrome] is a condition caused by a virus colled HIV.This virus attacks the immune system the body security force ,that fights off infections .when the immune system breaks down you lose this protection and can develop many serious,often deadly infection and cancers.These are colled opportunistic infection {OIS} becouse they take advantage of the body weakned defences.You have heard it said that some one"died of Ads" This is not entirely accurate ,since it is the opportunistic infections that cause death,Aids is the condition that lets the OIS take hold.

And what is hiv is the virus like a flur or cold. A virus is really nothing but a set of instructions for making new viruses,wrapped up in some fact,protein and sugar,without living cells, a virus can not do any thing _its like a brain with no body inoder to make more viruses(and to do all of the other nastly thing that viruses do} a virus has to infect acell,HIV mostly infects T_cells,also, knows as CD4+CELLS or T_helper cells.

These cells are white blood cells that turn the immune system on to fight desease.Once inside the cells,all of the drugs marketed to treat HIV work by interfering with this process.There,that wasnt so hard, was it.coming to my pont above why HIVis very dangerous?
The immune system is agroup of cells and organs that protect your body by fighting deseases.the human immune system usually fuids and kills viruses fairly quickly.So if the body immune system attacks and kills viruses,what the problem?

Different viruses attack different parts of the body _some may attack the skin,other the lungs,and so on.The cmmon cold is caused by a virus,what makes HIV so dengarous is that it attacks the immune system itself_the very thing that would normally get rid of virus, it particularly attacks a special type of immune system cell known as aCD4lymphocyte.
HIV has a number of tricks that help it to evade the body diffences including very rapid motation.This means that once HIV has taken hold, the immune system can never fully get rid of it.

There is not any way to tell just by looking of some once been infected by HIV, infact a person infected with HIV may look and feel perfectly well for many years and may not know that they are infected.But as a persons immune system weakness they become increasingly vulnerable to illnesses,many of which they would previously have fought off easily.

The only reliable way to tell whether some one has HIV is for them to take a blood test, which can detect infection from a few weeks after the first entered the body
There fore the HIV AIDS is very dengarous according to the above points.
