Brian Gerard Williams
HIV increases the likelihood that a person will develop TB. Starting them on anti-retroviral therapy (ART) reduces their risk of TB but not to the level in HIV negative people. Sin…
HIV, TB and ART: the CD4 enigma
Brian Williams, Eleanor Gouws
The concentration of CD4 T-lymphocytes (CD4 count), in a person's plasma is widely used to decide when to start HIV-positive people on anti-retroviral therapy (ART) and to predict…
Pre-exposure prophylaxis (PrEP) versus treatment-as-prevention (TasP) for the control of HIV: Where does the balance lie?
Brian G. Williams, Eleanor Gouws, John Hargrove +2
Anti-retroviral drugs can reduce the infectiousness of people living with HIV by about 96%--treatment as prevention or TasP--and can reduce the risk of being infected by an HIV pos…

In 2005 there was an outbreak of XDR (extensively drug resistant) TB in Tugela Ferry, which is served by the Church of Scotland Hospital (COSH), in the uMzinyathi District, KwaZulu…
The rate of decline of CD4 T-cells in people infected with HIV
Brian G. Williams, Eline L. Korenromp, Eleanor Gouws +1
In people infected with HIV the RNA viral load is a good predictor of the rate of loss of CD4 cells at a population level but there is still great variability in the rate of declin…
