The HSRC explained that the prevalence indicator could be misleading as it does not reflect the positive trends, such as the fact that HIV/Aids patients are living longer as a result of anti-retroviral treatment and more people are becoming aware of their HIV/Aids status. Prevalence is measured according to the number of new HIV incidents reported and the mortality rate of HIV infected people or Aids patients. The HSRC indicated that in the Western Cape, TB forms part the Burden of Disease Programme, whereby HIV/Aids and TB are diagnosed and treated together. This has resulted in cost savings and improved diagnosis and treatment of HIV/Aids and TB. The HSRC were also of the opinion that the Western Cape model could possibly be implemented across the country.
