A Review COVID 19 : A Zoonotic Disease and a Relentless Widespread Global Pandemic

Abstract

A zoonosis or zoonotic disease is an infectious disease that is transmitted between species from animals to humans (or from humans to animals). Some don’t make the animal sick but will sicken a human. Zoonotic diseases range from minor short-term illness to a major life-changing illness. The zoonotic transmission may take place in any context in which there is contact of human with animals such as through consumption of animal meat or using animal products , through pets, farming, butchering, hunting , bushmeat or using animals in any kind of research context. Zoonoses can also be transmitted through the air or with contact of an infected animal through insect bites or animal bites. Many zoonotic diseases are very difficult to control and sometime uncontrollable. It is seen that the risk of becoming infected with a zoonotic disease is increased in person affected by immunosuppression from a preexisting disease or medication. In this review article the main objective is to study on the present pandemic that the world is facing Covid 19 SARS CoV 2 and which is already declared as a zoonotic disease by many researchers and scientists. It also aims that COVID -19 has zoonotic source. The focus is basically on the previous studies done related to the same (Zoonotic diseases and Covid 19 and their connection). It also aims upon the outlook of zoonotic diseases that varies on the types of diseases, pathogens, animals involved, mode of transmission and emergence. Taking the example of the highly pandemic zoonotic diseases such as Rabies, Swine influenza, West Nile fever, Zika fever, HIV, Ebola virus, SARS coronavirus, MERS coronavirus and Covid 19 SARS Cov 2 all are of great concern and need to be studied.
