Tuberculosis has been an illness that has been around since time immemorial. Even though the incidence of the disease may not be often heard of in our circles, it is far more common than we think. Unfortunately, it is also one of the most fatal diseases in the world, as has been revealed by the World Health Organisation (WHO). The illness, caused by the bacteria mycobacterium tuberculosis, is so dangerous that patients can lose their lives within a few months.
