COVID 19 is a virus which originated from the city of Wuhan, China. This virus is similar to the earlier SARS-COV and MERS. The present day scenario is considered as the third pandemic in this century as issued by the WHO. Till now COVID-19 has infected more than 50 lac people across the globe and more than 2.5 lac people died due to it.[4]However, despite the seemingly unpredictable nature of disease emergence, there are lessons to be learned from the origins of recently emerged diseases as well as those that have their origins in the more distant past, lessons that may offer clues as to how future infectious disease outbreaks and pandemics may be prevented. The challenge lies in using the accumulated, albeit incomplete, knowledge gained from emergent diseases of our past to identify practical solutions and strategies aimed at detecting and halting future threats. Here, we review the field's current understanding of the origins of infectious diseases and the factors that contribute to their emergence. We are also highlighting the importance of the zoonotic transmission of pathogenic agents from animals to humans, the favoured mechanism by which emergent diseases have come to afflict humans throughout history comparison of related epidemics/pandemics in the past and the economic implications faced by the world.[1, 2, 3] Despite the fact that most emerging diseases stem from the transmission of pathogenic agents from animals to humans, the factors that mediate this process are still ill defined. What is known, however, is that the interface between humans and animals is of paramount importance in the process. Improving our understanding of this interface will be crucial to future pandemic prevention efforts.
