After various delays and setbacks, a new, less toxic, short-course tuberculosis preventive therapy called 3HP is finally being launched in six districts in South Africa. Tiyese Jeranji reports.
While likely millions of people in South Africa have latent tuberculosis (TB) infection, only between three and 10% of these people ever fall ill with TB. Cutting-edge research conducted in South Africa has now taken us a significant step closer to a test that can predict who will and who will not fall ill with TB. Such a test, if simple and affordable, could potentially revolutionise TB prevention efforts.
