Tuberculosis (TB) persists as a global health challenge, especially in low- and middle-income countries. Despite historical advancements, TB remains one of the top causes of death worldwide, claiming 1.5 million lives in 2020 alone. Tuberculosis (TB) is an infectious disease that most often affects the lungs. TB is caused by a type of bacteria called Mycobacterium tuberculosis. It spreads through the air when infected people cough, sneeze or spit.
TB primarily affects the lungs, causing symptoms such as a persistent cough, chest pain, and weight loss. However, it can also target other parts of the body, presenting with a range of symptoms depending on the affected area. Diagnosis involves imaging tests and microbiological examinations, with treatment requiring a multi-drug regimen over several months.
Prevention strategies include vaccination with the BCG vaccine, infection control measures like proper ventilation, and addressing social determinants such as poverty and access to healthcare. Treating latent TB infection is also crucial in preventing its progression to active disease.
The rise of drug-resistant TB strains, such as multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB), poses significant challenges to effective treatment. Strict adherence to treatment protocols and the development of new drugs are essential in combating these resistant forms.
The WHO’s End TB Strategy aims to reduce TB deaths by 95% and new cases by 90% by 2035, providing a framework for global action. Advancements in research and a focus on equitable healthcare access are critical components of this strategy.
TB’s enduring impact highlights the ongoing need for comprehensive approaches to public health. By addressing social disparities, investing in healthcare infrastructure, and advancing research, we can move closer to a world where TB no longer poses a significant threat. It is through sustained efforts and global collaboration that we can envision a future free from the burden of tuberculosis.
