B90: Sequelae of tuberculosis

Sequelae of tuberculosis refers to the long-term health problems that can occur as a result of tuberculosis (TB), a bacterial infection that primarily affects the lungs but can impact other systems of the body as well. This happens when the TB bacteria, transmitted through droplets in the air from a cough or sneeze from someone with the active disease, invade and damage tissues in the body. Once the acute phase of TB is over, some people may experience complications, collectively known as the sequelae of tuberculosis. These can range from minor functional impairments to severe lung damage, and may include persistent cough, breathing difficulties, chest pain and even long-term damage to other organs that were involved during the active disease phase. These sequelae can occur irrespective of whether the TB was fully treated or not, and they can sometimes appear years after the active infection has been cured. They can cause significant impairment in daily activities and overall quality of life. The aim of treatment is to manage these sequelae and help alleviate symptoms.
