A potentially dangerous infectious disease that mostly affects the lungs is tuberculosis (TB). People can contract tuberculosis from one another by coughing or sneezing small droplets of bacteria into the air. Weight loss, fever, night sweats, and generalised sensations of sickness or weakness are all common signs of TB disease. TB progresses via 3 stages. They are latent and active disease, as well as exposure. The infection can be detected with a TB skin test or TB blood test. Learn more about it by looking through this PPT.
