It’s a highly contagious disease which means it can travel from one person(Infected) to another person(healthy) however, its symptoms may vary. If not treated on time it can lead to death as well because infection spread very fast in the body affecting other organs such as liver, kidney, and lungs. Government organizes various drives to control it through doorstep visits to electronic mediums.  Most common diagnostic test for TB is a skin test where a small injection of PPD tuberculin, an extract of the TB bacterium, is made just below the inside forearm.

It is difficult to diagnose the latent TB due to the absence of abnormality in chest X-ray however, tuberculin skin test (TST) can be used to diagnose the latent TB. It’s a non-contagious disease but it can lead to immune system failure if not treated timely. Individual suffering through latent TB are prone to get infected by HIV as the immune system is not strong enough to protect the body from the infection or disease
