What is active tuberculosis?
Active tuberculosis is a multiorgan disease caused by primary infection or as a reactivation of latent tuberculosis. Accordingly, active tuberculosis could be primary tuberculosis or reactivation tuberculosis. Primary tuberculosis occurs when the immune system is unable to defend against the Mycobacterium tuberculosis bacterium (MTB) infection. Reactivation tuberculosis, as the name suggests, is the reactivation of contained mycobacterial infection. Reactivation Tb is the most common form of active tuberculosis, representing 90% of the cases. The lung is the most commonly involved organ, other organ systems commonly affected include the gastrointestinal system, the musculoskeletal system, the lymphoreticular system, skin, liver, and the reproductive system.[1]

The World Health Organization estimates that, annually, around 8 million people develop active tuberculosis globally, and nearly 2 million people die from the disease. Of every 10 people infected with M. tuberculosis, one may develop an active infection sometime in their lifetime. After infection, the risk of developing active tuberculosis is highest in the first year, but the active disease usually occurs many years later in most patients. This activity outlines the evaluation and management of active tuberculosis and highlights the role of the interprofessional team in evaluating and treating patients with this condition.
