Coronaviruses are a family of viruses. Coronaviruses are zoonotic (first develop in animals before developing in humans). virus transmission from animals to humans due to close contact with an animal that carries the infection. Coronaviruses can be spread from person to person through respiratory droplets( wet stuff that moves through the air when you cough or sneeze). The viral material hangs out in these droplets and can be breathed into the respiratory tract (your windpipe and lungs)leading to infection. Researchers believe that possibly the virus may have been transmitted to humans via bats to another animal — either snakes or pangolins. This transmission likely occurred in the open food market in Wuhan, China, or may have been engineered by a lab in Wuhan.
