In the last 20 years the number of new tuberculosis (TB) cases had tripled in high HIV prevalence countries, and at least a third of the world’s 33.2 million persons living with HIV/AIDS (PLWHA) are infected with TB. Approximately 80% of people with TB/HIV infections live in sub-Saharan Africa, where TB is the leading cause Read More
The central theme of this SACEMA Quarterly is the HIV/TB co-epidemic. From 1-4 June 2010 the 2nd TB conference was held in Durban, in which most of the presentations discussed TB in relation to HIV. A SACEMA affiliate presented a study concluding that intensified HIV testing and early initiation of antiretroviral therapy (ART) for women and men aged 25-40 would optimise the cost-effectiveness of applying the test-and-treat strategy in South Africa, as this would have the largest impact on TB as well. One of the main articles in this Quarterly discusses whether ART will help, and to what extend, in lowering TB incidence. Other articles focus on meaningful statistical modelling in public health, and the Zibambele programme (job creation and poverty alleviation) and it’s role in the battle against HIV/AIDS and TB. Finally, the new director of SACEMA is announced: Dr. Alex Welte.
A significant contributing factor to the high incidence rates of tuberculosis (TB) in countries such as South Africa is the phenomenon of reinfection leading to further disease episodes. Researchers of SACEMA explored the relationship between incidence of TB and reinfection further by constructing a model that simulates the epidemiology of a TB endemic. This article describes the results of this analysis and recommendations based on these.
