The viral material hangs out in these droplets and can be breathed into the respiratory tract (your windpipe and lungs), where the virus can then lead to an infection. The 2019 coronavirus hasn’t been definitively linked to a specific animal. Researchers believe that the virus may have been passed from bats to another animal — either snakes or pangolins — and then transmitted to humans. This transmission likely occurred in the open food market in Wuhan, China.
