Acquired Immuno-Deficiency Syndrome (AIDS)
AIDS stands for acquired immunodeficiency syndrome. caused by the retrovirus HIV, resulting in a defect in cell-mediated immune response that is manifested by increased susceptibility to opportunistic infections and to certain rare cancers, especially Kaposi's sarcoma. It generally occurs when the CD4 count is below 200/mL and is characterized by the appearance of opportunistic infections. These are infections that take advantage of a weakened immune system. It is very easily transmitted by exposure to contaminated body fluids, especially blood and semen.
The main cause of AIDS is the HIV virus. It attacks and destroys certain types of cells that are part of the immune system and leaves the body vulnerable to a variety of life-threatening illnesses and cancers. The immune system consists of all those cells, tissues, and substances that protect the body from infection by foreign bodies, such as bacteria.
The human immune system is immensely complex and there are many ways in which it can be affected by a retrovirus such as HIV. Furthermore, it is also not clear what role (if any) other factors - known as co-factors - may play in the development of immune damage. HIV is a highly contagious virus, but the way of transferring of this virus is not the same as is measles or chicken pox. It spreads from one person to other through may other ways like:
People suffering with HIV virus infection show different signs and symptoms as their infection progresses. Only a doctor can tell the exactly what are these signs and symptoms conveying. At first, many people with HIV have flu-like symptoms, followed by a period of no symptoms at all. The symptoms of AIDS are primarily the result of infections that do not normally develop in individuals with healthy immune systems. These are called "opportunistic infections."
Some of the Common Symptoms of AIDS may be:
In some other Severe cases there may also be:
Treatment for AIDS (Acquired Immuno-Deficiency Syndrome)
There is no cure for AIDS as such - so the only thing we can do is - prevent it from occuring. Combinations of antiviral drugs and drugs that boost the immune system have allowed many people with HIV to resist infections, stay healthy, and prolong their lives, but these medications are not a cure. Right now there is no vaccine to prevent HIV and AIDS, though reaserches are going on.
Primary therapy for HIV infection includes three different types of antiretroviral agents:
