HIV/AIDS
Introduction
HIV, also known and the human immunodeficiency virus attacks and destroys the CD4 cells, these cells also known as the T-lymphocytes are a type of white blood cell found in the immune system which have the role of preventing disease, when the level of the CD4 cell decreases the ability of the body to fight and prevent disease also reduces; at this stage the person is said to have acquired immunodeficiency syndrome (AIDs)
Epidemiology
According to the world health organisation (WHO) there were 35.3 million people living with HIV in 2012. In the same year WHO had reported that 1.6 million had died due AIDs associated illnesses. (WHO, 2014)
Development of HIV
During the early period of the infection the person experiences flu like symptoms. Symptoms include swollen glands, sore throat, rash, fatigue and headache. At this point the virus is reproducing rapidly and is using the CD4 cells to do this; in the process of the virus reproducing the CD4 calls are killed hence the level of these cells falls. Eventually an immune response will cause the level of the virus to decrease, this will allow the level of the CD4 cells to increase but the level of these cells doesn’t return to the original state. As the virus continues to develop within the body the person doesn’t really experience HIV-related symptoms, during this stage the virus is active but is replicating slowly. Once the immune system is fully damaged, the level of the CD4 cells rapidly decreases and the body becomes susceptible to diseases/infections when this happens the person is said to have AIDS.
