HIV and AIDS #1: Understanding AIDS
You probably heard a lot of confusing talk about the disease known as AIDS. Sore throat exactly is it?
Alice W. Ko.
AIDS is a disease that represents the final stages of infection with incurable virus known as Human Immunodeficiency Virus or HIV. To understand how AIDS work it helps to have a grasp of HIV. Simply put HIV attacks and destroys cells in immune system much as an invading army might destroy a high wall that protects that protects the city. With a weakened immune system a person become less able to fight often infections before HIV can attack it has to get in HIV lives in bodily fluids like semen, vaginal secretions, blood and breast milk. A person who carries HIV can passed it another through any of this usually via sexually intercourse, breast feeding or the sharing of drug paraphernalia.
Rarely a person will contract HIV through blood transfusions and well it is highly unlike for people to acquire HIV through saliva it is possible to passed is through oral sex. Once the virus is transferred it attaches to it new host body CD for cells or T-cells which are integral parts of the immune system. Inside the T-cell HIV literally changes to become part of the bodies DNA or genetic code. At this point the body will be force to produce the virus because HIV lives the immune system everytime of form invader triggers it system to work. HIV is activated too. This means that one good T-cell fight for example the flue virus new HIV particle are forms during the first stage and weeks after person is infected with HIV he or she may experiences flue like symptoms such as a fever, fatigue and enlargement nodes. These symptoms generally disappear without treatment but as the body is force to create new HIV cells the immune system gets weaker. A progression that can take form several months to more than 10 years.
Eventually, untreated HIV leads to acquired immune deficiency syndrome of AIDS. The name is appropriate acquired means to obtain an infection, immune deficiency refers to weakness and immune system and syndrome is a group of problems that comprise a disease. AIDS is generally diagnose by a blood or saliva test that measures the CD for cells and a persons body. If a count drops below 200 the immune system is seriously damaged and unable to fight infections properly. A diagnosis of aids also occurs if a person get one of the 26 opportunistic infections, which are conditions coming in an advance HIV patients but rarely found in people with intact immune systems.
