Emerging and re-emerging bacterial diseases in India

Abstract

There has been a remarkable progress in the prevention,control and even eradication of infectious diseases with improved hygiene and development of antimicrobials and vaccines. However,infectious diseases still remain a leading cause of global disease burden with high morbidity and mortality especially in the developing world. Furthermore, there have been threats of new diseases during the past three decades due to the evolution and adaptation of microbes and the re-emergence of old diseases due to the development of antimicrobial resistance and the capacity to spread to new geographic areas. The impact of the emerging and re-emerging diseases in India has been tremendous at socioeconomic and public health levels. Their control requires continuing surveillance,research and training,better diagnostic facilities and improved public health system. Emerging and reemerging zoonotic diseases, foodborne and waterborne diseases and diseases caused by multiresistant organisms constitute the major threats in India. This review of bacterial emerging and re-emerging diseases should be of critical importance to microbiologists,clinicians,public health personnel and policy makers in India.
