The COVID-19 outbreak is currently going the world over. No specific therapeutics and vaccines are available for disease control, the epidemic of COVID-19 is posing a great threat for global public health.
Virology is broad segment that studies viruses and help in understanding about the infections, mechanism of viruses on the host cells and others. The understanding of the virology helps in preventing the epidemic of the diseases and designing the treatment for various diseases. The virology also helps in the drug formulation and development. In good health the human is colonized by bacteria on the skin and mucous surfaces, especially in the gastrointestinal tract, a number that is equal to the number of cells in our own body. Despite all these direct encounters, only a handful of bacterial species are known to spread into the body to produce serious infections.
Infectious disease is a leading cause of death, disability and social and economic disorder in millions of people worldwide. Poverty, poor access to health care, human migration, emerging disease agents and antibiotic resistance all contribute to the expanding effects of these diseases. The strategy for the prevention and treatment of infectious diseases is derived from an in-depth understanding of complex interactions between specific viral or bacterial pathogens and human (or animal) hosts.
The discoveries emanating from virology have been astonishing in the last 50 years, and some of them could have been predicted or even imagined based on prior knowledge. It is no accident that virologists have played a major role in the biological revolutions of the last century. Viral gene products attach to all important nodes of biology, ranging from atom to organism, and thus serve as ideal tools to dissect the most complex processes of life. Our joys and challenges are to identify and understand these biological nodes and find out from this information how viruses replicate, spread, and sometimes cause disease. We can say with certainty that virology will continue to prosper in the 21st century.
