Abstract
Tuberculosis (TB) is still a leading cause of death worldwide. Almost a third of the world's population is infected with TB bacilli, and each year approximately 8 million people develop active tuberculosis and 2 million die as a result. However, there are few studies of long-term TB treatment outcomes from Directly Observed Therapy, Short-course (DOTS) programs in high-burden settings and particularly settings of high drug resistance. This study is a systematic review to evidence the incidence and prevalence of latent TB infection (LTBI) and disease and to evaluate the impact of various preventive strategies that have been attempted. To identify relevant studies, we searched electronic databases and journals, and contacted experts in the field. This review demonstrates that, various types of tuberculosis have different imaging findings, and typical computed tomography (CT) and magnetic resonance (MG) findings can suggest the diagnosis. Available evidence reinforces the need to design and implement simple, effective, and affordable tuberculosis infection-control programs in health-care facilities in our countries. With the revision of all the data's, we are able to conclude that the controlling of tuberculosis by human beings is yet not achieved. So, there is an urgency to develop awareness amongst the individuals and also a new drugs regimen for the proper treatment of tuberculosis.
