President Jacob Zuma, in his World AIDS Day address, has committed government to raising the initiation threshold to 350, albeit only for pregnant women and those with tuberculosis. A Department of Health proposal to give access to all patients with a CD4 count less than 350 is currently being...
CD4 cellsare a subset of our immune system that are essential for the teamwork of all other immune cells. They help the other immune cells to launch a well-coordinated attack when there is an intruder such as a virus, bacterium, and the like. CD4s tell the other cells who the intruder...
A viral load test two to eight weeks after you start or change treatment helps your doctor decide how well the ART is working. A CD4 test will show whether the immune system is improving in response to ART. Then you should typically get a CD4 test every three to six months, or as oft...
HIV is a viral infection that slowly weakens your immune system. The virus kills a type of white blood cell called CD4. A normal CD4 count ranges from 500 to 2,000. You have HIV when your CD4 count ranges from 200 to 500. You have AIDS (acquired immune deficiency syndrome) when your...

The most objectively substantiated health-related reason for tanning is that it improves vitamin D status. The serum 25-hydroxyvitamin D concentration (25(OH)D) is the measure of vitamin D nutrition status. Human biology was probably optimized through natural selection for a sun-rich environment th...

CD4 cells, for example, are a kind of T cell which decline radically in patients with HIV. In people of normal health, the CD4 count is usually above 1,000, while AIDS patients have 200 or fewer CD4 cells in their blood tests. If a test reveals that a patient has an unusually low ...
