| In 1948 BC, ancient text by the Babylonian monarch Hammurabi mentions a chronic lung disease that is likely TB (Herzog, 1998). Next, Famous Greek physician Hippocrates (460-370 BC), proposed the concept of pulmonary phthisis (tuberculosis) as a common disease that usually leads to death, however he believed that it was hereditary.

| The world health organization defines TB as one of the top ten causes of death worldwide. All age groups are at risk of contracting the disease notably, individuals who are HIV positive are 20 to 30 times more likely to develop the active form of TB thus speeding the progression of both diseases. Approximately one quarter of the world's population has latent TB, these individuals have a 5-15% risk of developing active TB (WHO, 2018). The majority of cases and deaths are in developing countries although cases occur in every part of the world. India and China account for 40% of the total global TB cases. This is because TB is usually unrecognized till symptoms show additionally, the route of transmission via air particles is undetected. In spite of this, the global incidence of TB is decreasing by 2% each year (WHO, 2018). | The world health organization defines TB as one of the top ten causes of death worldwide.
