Tuberculosis (TB) is a curable disease that claims the lives of millions each year. TB is an airborne disease spread by inhaling droplets of the tubercle bacillus. There are two different types of TB related conditions; latent TB infection and active TB disease. During latent TB, an individual inhales droplets of tubercle bacillus but the immune system can fight off this infection. However, once droplets of tubercle bacillus penetrate the alveoli, and colonization of droplets multiply, latent TB transitions into active TB disease (Katanekwa & Dahlback, 2016, p. 9). TB is typically found in the lungs but can also develop in the brain, bone, or kidneys (Parmer, Allen, Walton, 2017, p. 27). According to the World Health Organization, TB is ranked as one of the top leading causes of death (WHO, 2018). While TB was discovered over two thousand years ago by Hippocrates, this disease continues to claim lives each year (Katanekwa & Dahlback, 2016, p.9). This poster will highlight the pathogenesis of TB, associated risk factors, signs and symptoms of TB, diagnostic testing, treatment, and nursing implications. Ultimately, by prompt diagnosis and treatment, prevention and eradication of TB can be accomplished. This poster intends to shed light on how to tackle and eliminate this deadly disease.
