The reasons for this situation are easily identified in some cases as associated with treatment modalities (permissive use of antibiotics), the industrial use of antibiotics, demographic changes, societal behavior patterns, changes in ecology, global warming, the inability to deliver minimal health care and the neglect

Why is tuberculosis a re emerging disease?
Tuberculosis a re-emerging disease. Two billion people, nearly one-third of the population worldwide, are infected by M. tuberculosis. Moreover, the large use of TNF inhibitors has created a new risk group for the disease, highlighting the need for tougher screening practices to reduce new cases of severe TB.
What are the challenges in combating emerging and reemerging diseases?
But despite considerable progress, infectious diseases continue to present significant challenges as new microbial threats emerge and reemerge. HIV/AIDS, malaria, tuberculosis, influenza, SARS, West Nile virus, Marburg virus, and bioterrorism are examples of some of the emerging and reemerging threats.
