Main description:

Coronavirus disease 2019 (COVID-19) first identified in Wuhan City in December 2019 spread throughout Hubei Province and other parts of China After causing significant morbidity and mortality in China, by February 2020, it had spread to numerous other countries, infecting millions people and caused a large number of deaths across the world and is therefore considered a global pandemic.

The outbreak of Covid 19 pandemic put in a burden on almost all the areas including health-care systems, education, life style, aviation throughout the world. This outbreak revealed the world's poor health system and has had a negative influence on healthcare personnel in every way. Because they came into touch with infected people on a regular basis, became more prone to COVID-19 infection than the general population. The virus is able to attack not only the respiratory tract, but almost all the organs including brain. Impacts on gut biota have also been noticed. This caused both morbidity and mortality in humans without any geographical, cultural, religious barriers. The emergence of new variants due to mutations in the virus has aggravated the problem. Whereas delta variant brought in second wave was very disastrous killing a large number of people due to various factors such as lowering of saturated oxygen in blood and other physiological emergencies. The omicron variant has proved to be less lethal. Though the pandemic has subsided, the emergence of sub variants BA1 and BA2 and now their hybrid have started giving horror feelings in many countries. The increase in the number of cases at exponential level has forced many states in China to impose lockdown. As the conditions laid down to combat the pandemic have been relaxed, and movements from one part of the globe to the other have started, the virus may reach other countries and the make people to suffer with pandemic forcing those countries to resort to lockdown again.

Covid 19 sparked the minds of scientific community to make all out efforts to delineate the structure and functions and its mechanistic approach to cause disease in humans. Besides, attempts to develop new drugs, they made sincere efforts to repurpose the available drugs to be used against the virus and develop a series of vaccines in a shortest period, not possible in the normal times. The mild effect of omicron might have been due to the extensive vaccination programmes carried out in various countries. There is, however genuine fear that the new emerging variants may evade the immune system and cause damage to the body.

The rapidly growing demand on health facilities and health care employees threatened to overburden some health systems and render them unable to function properly. This had a direct impact on health care professionals. All the energies in the nations world over focused on controlling the transmission and curtailing morbidity and mortality due to the pandemic. Despite all the complexities and hardships that health care employees faced, they continued to put in their best efforts in serving the community and society at a large.

The present book highlights the impact of covid 19on science, health and health care system. The chapters included in the volume are hard work of dedicated experts in the field. These include the description of insight of the evolution, structure and mode of infection as well as strategies to attack various organs in the body. A separate chapter explains the emergence of various strains of virus. The preparedness of hospitals and health care workers as well as different agencies such as DRDO to face the challenges posed by virus have also been discussed. The way scientists and technologists developed new techniques to detect and control the virus have also been highlighted. It also includes the chapter on the development of vaccines to control the pandemic.

This book will be compendium for students,teachers,medical personnel, administrators and public as whole.
