lefttopBats Viral Hosting Capacity and their defence systemBats are recognized as the only flying animal. For centuries now, they have been associated with contagious infections. They have led to the outbreak of emerging viral infections such as Hendra, Nipah, COVID-19, and Ebola. These viruses have adverse effects on human beings, as evidenced by the COVID-19 pandemic that led to the death of more than 1.6 million people as of 21st December 2020. Humans acquire viruses from bats because they are in constant contact with them due to anthropogenic alteration of their natural habitats. The alteration triggers them to find other alternatives, which increases frequent interaction with humans. The connection between bats and viruses is interesting because they exhibit no or very few clinical symptoms even when high viral titres are found in tissue or sera, indicating that they are resistant to viral infections. These startling discoveries have triggered the need to study the bats' viral hosting capacity and defence system. Bats Viral Hosting CapacityBats' reservoir for viruses has been studied for decades. Initial studies discovered SARS-related coronaviruses in bats and established that they were rich harbors of genetically diverse coronaviruses. Further, New and re-emerging researchers have documented
