HIV vs. AIDS

Difference Between HIV and AIDS

There are differences between HIV and AIDS .

AIDS is a disease called Acquired Immune Deficiency Syndrome, which is caused by the HIV Virus (Human Immunodeficiency Virus). HIV virus destroys the cells in the human body that resist infections, thereby weakening it so that it is unable to resist infection. This disease is known as AIDS.

HIV

HIV (Human Immunodeficiency Virus), is so called because this virus attacks the healthy immune system of the humans and continues to weakens it until the person is unable to ward off common infections. Once a person acquires HIV, he becomes HIV positive and remains so all his life. This is the stage when the white blood cells count goes below 200 and the person develops one or more common infections which his immune system is unable to resist. This is the final stage of the disease and the person is said to be suffering from AIDS. The infections that may afflict a person who is HIV positive are memory loss, Pneumonia, Kaposi Sarcoma, weight loss, Tuberculosis etc. The symptoms of HIV are fever, headaches, sore Throat, muscle and joint pains, swollen lymph nodes, skin rashes. Some of the main reason of HIV is unprotected sex, sharing infected needles and infected mothers passing the virus to babies during pregnancy.

Reasons or causes of HIV

AIDS

AIDS is the advanced stage of HIV. It is a disease called Acquired Immune Deficiency Syndrome and a person who is with AIDS may have many diseases and infections. A person develops these over a long period of time due to a gradually weak immune system. As a result he becomes very weak, and develops infections which a normal person is able to resist easily. AIDS takes quite some time to develop and a person who is HIV+ may remain healthy for 2-10 years before he becomes an AIDS patient.
If some is HIV positive, it does not mean that he has AIDS. It takes many years for HIV to progress to AIDS. If treated properly, HIV can be kept under control.
