The Human Immunodeficiency Virus binds itself to the receptors of the CD4 or T-cells of the white blood cells and then goes on to inject its RNA to it once it gets inside a person's body. 


Taking advantage of the host cells, it then starts replicating and multiplying. The virus takes over the host cell and as a result, the quantity of CD4 cells lowers. 

 


The body's immune system never stops to fight off this virus and after five or so years,  the immune system starts to lose the war and the body becomes greatly at risk of several serious complications. 


The common signs and symptoms of HIV infection are:


Rash

Vomiting

Nausea

Headaches

Fever

Inflamed glands

Muscle ache

Oral thrush

Cough

Fatigue

Appetite loss

Weight loss

Diarrhea

Sore throat


If these symptoms are ignored, the disease can progress to AIDS, where a critical decrease in the lymphocytes contained in the blood occurs and the immunity of body is totally ruined, allowing it to be at risk of contracting other diseases and infections.


People with AIDS are in dangers of having Kaposi’s sarcoma, lymphoma, drastic weight loss, lesions all over mouth and tongue, pneumonia with night sweats, high fever, and intense fatigue.


So, to avoid all these, get an HIV test as soon as possible to receive the right treatment at the earliest chance.
