According to a new scientific paper by the University of Rochester, bats are immune to the Covid-19 virus. The research credits their ability to control body inflammation that gives them their rock-solid immunity. Bats are able to prevent the multiplication of the virus in their bodies, the report states. The research adds that their ability to fly gives them the perfect immuno-response. The mammals are able to get used to 'sudden ups and downs' and metabolism changes in their bodies. The researchers have also attributed their environment as a reason for their stronger immunity. Bats' immunities are at a 'never-ending' war with various viruses and pathogens that exist in the environment, say experts. The review was published in the journal Cell Metabolism.
