Abstract
Human health has been drastically affected due to the emergence of many new and deadly viral infections and also the older that persists, despite much wonderful progress in the area of Biomedical sciences. Some of the best examples which could be cited here is the newly evolving Corona virus (Covid-19) or the virus of 21st century and other several viruses which have been already evolved disturbing the existence of human kind such as Zika virus, Dengue virus [4]. Chikungunya virus, Influenza A virus, SARS, MERS which are known to be transferred in mankind through many arthropods, some animals and several other methods of communication, for this the better understanding of the host pathogen association and relationship with its environment is necessary for the vector control methods which would be used for the prevention of these arboreal infections and this has been proved to be effective in many aspects of controlling the effect of the virus. The main cause of evolution of such pathogenic viruses can be any among some of these such as changing climatic conditions, poor sanitization, increase in population rapidly, rampant construction, uncooked meats etc., and many new evolving anthropophilic vectors which transfer such diseases in humans. Many recent researches have been reported which have shown the immense effort of Medical sciences and scientist to cure various deadly diseases such as HIV, Hepatitis, Chikungunya etc. and to some extent these viruses have been overcome but the nature of viruses is unpredictable and could re-emerge any time in the history which would hamper the control and preventive measures.
Highlights
The advancement of mankind from early man to modern man is a great achievement in itself, but along with the transformation of human many other positive and negative interactions related to humans have evolved such as its environment, human lifestyle, way of sustenance, and various diseases and its disease-causing pathogens which limits the activity of humans and its functioning system i.e. its immune.As the progress in the human has occurred over time along with its new techniques and technologies such as the increase in number, density etc. along with which evolved certain number of diseases and its pathogens
The evidence of these pathogens, pathogenic diseases and all about human body has been studied by various researchers since pre-historic times which gives us the clear details about the development of human body over times along with its environment but more or less it has provided us the detail of Association and interaction of viruses and many other pathogens along with their resistant evolution and long lasting effect
Dated back since the evolution of Tobacco mosaic virus (1892) to the evolution of Foot and mouth disease virus (1898) and the virus of new world i.e. Corona virus (2020), it was Yellow fever virus (1901) which was first obtained in filtered form and from the study of viruses became a bit easier and with evolution of techniques with times we developed several vaccines and antibiotics related to evolving viruses and till date (21st century) the viruses have become the most highly evolved pathogen in much newer and efficient forms, Covid-19 can be cited as one of the examples, and many will keep on evolving along with the passage of time and with the level of human and environment evolution, being the rule of nature
Summary
The advancement of mankind from early man to modern man is a great achievement in itself, but along with the transformation of human many other positive and negative interactions related to humans have evolved such as its environment, human lifestyle, way of sustenance, and various diseases and its disease-causing pathogens which limits the activity of humans and its functioning system i.e. its immune. As the viruses are the highly evolved pathogen from time immemorial causing from simple cold and cough to a deadly Corona disease and many much to be evolved in near future. This Review paper deals with an approach to combine all the viruses attacking the human body and their diversity, the level of harm they could do to body and their distribution in India level and around the world. Shedding of scalp hair which increases with high frequency abnormally either through direct infection or by killing the cells of hair follicle This virus may show interference with the normal hair cycle through some mediators like cytokines. Spread by- Saliva, Nasal and throat discharge, stool, Respiratory droplet etc
