Tuberculosis (TB) remains one of the deadliest infectious diseases responsible for millions of deaths annually across the world. In this paper we present a general overview of TB including the pathogenesis, diagnosis, and treatment guidelines. In preparation of this write up, we searched PubMed for relevant articles on TB. Additionally, we searched the websites of international institutions like the World Health Organisation (WHO) and the US Centres for Disease control and Prevention (CDC) for related reports and clinical guidelines. This paper has been written with the intention to offer general education to health professionals, policy makers, patients and the public.
