What does AIDS stand for? What causes AIDS?

    AIDS stands for "acquired immunodeficiency syndrome." AIDS is introduced on by the hiv (HIV) and is the most innovative level of HIV disease.

10. Picture of HIV/AIDS

The virus is propagate through contact with contaminated blood or contaminated liquids such as sexual secretions (stage 1). Over time, the virus strikes the immune system, concentrating on unique tissues known as "CD4 cells" which are important in defending the body from strikes and malignancies, and the number of these tissues begins to drop (stage 2). Gradually, the CD4 cells drop to a critical level and/or the defense mechanisms is damaged so much that it can no longer battle off certain types of strikes and malignancies. This innovative level of disease (stage 3) with HIV is known as AIDS.

HIV is a very little virus that contains ribonucleic acid (RNA) as its genetic material. When HIV infects animal cells, it uses a unique enzyme, reverse transcriptase, to turn (transcribe) its RNA into DNA. (Viruses that use reverse transcriptase are sometimes termed as "retroviruses.") When HIV reproduces, it is vulnerable to making little genetic errors or strains, resulting in germs that differ a little bit from each other. This ability to create minimal modifications allows HIV to evade your immunologic resistance, basically resulting in long term disease, and has made it difficult to make an effective vaccine. The strains also allow HIV to become immune to medicines.
