The incidence of emerging infectious diseases in humans has increased within the recent past or threatens to increase in the near future. Over 30 new infectious agents have been detected worldwide in the last three decades; 60 per cent of these are of zoonotic origin. Developing countries such as India suffer disproportionately from the burden of infectious diseases given the confluence of existing environmental, socio-economic, and demographic factors.

Emerging & re-emerging infections in India: An overview

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.

Except where otherwise stated, drug dosages and recommendations are for the non-pregnant adult who is not breastfeeding. The microbial world is complex, dynamic and constantly evolving. Infectious agents reproduce rapidly, mutate frequently, cross the species barrier between animal hosts and humans, and adapt with relative ease to their new environments. Because of these traits, infectious agents are able to alter their epidemiology, their virulence, and their susceptibility to anti-infective drugs.

Infectious diseases continue to impose unpredictable burdens on global health and economies, a subject that requires constant research and updates. The results show that wild animals mainly bats, birds and primates play an important role in the dissemination of etiological agents mainly viruses, as a new coronavirus called Novel Coronavirus in extensive geographic regions. Moreover, these wild animal organisms can act as the site for essential biotic synergy among several pathogenic microorganisms, promoting a higher rate of adaptation, mutation and even genetic recombination, with consequent stimulation of new strains and subtypes, inducing new infectious agents with unknown virulent potential. In conclusion, the monitoring of these diseases and adequate preparation for possible epidemics and pandemics are fundamental conditions for the mitigation of their future impact. The zoonotic threat of these etiological agents and the impact on public health can be enormous as shown by the ongoing epidemic of novel coronavirus nCoV infections.

Infectious viral diseases are the never-ending challenge that can emerge or re-emerge in unpredictable regions and at unpredictable times. Human beings are facing an intractable problem in unexpected time and place due to these viral diseases. Human, ecological, and viral related factors are the contributing factors in the emergence or re-emergence of viral infectious disease. Travel, mass gathering, urbanization, fragile or deteriorated health systems, weak disease surveillance system, limited laboratory diagnostic capacity, war, migration, poor hygienic practice, illegal animal trade, hunting and eating infected animals are among human-related factors that contribute in emergence or re-emergence of viral infectious disease. Deforestation, climate change, invasion of animal habitats, the building of dams and intensive agricultural practice are contributing factors to the emergence or re-emergence of viral infectious disease. The last but not least risk factor for emergence or re-emergence of infectious viral disease is the virus-related factors.

Emerging and re-emerging infectious diseases: a potential pandemic threat

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.
