The novel coronavirus pneumonia (NCP, 新型冠状病毒肺炎) broke out in China that we have never seen before. It was first found in the Huanan Seafood Market in Wuhan, where some wild animals were on sale. Scientists have found that the virus likely came from bats and was then spread to humans from some wild animals. Bats can carry and spread more than 60 viruses that can infect humans including the world’s deadliest viruses, such as Ebola and SARS.But bats have special immune (免疫的) systems that allow them to live with viruses without getting sick. Other wild animals are also hosts of many viruses. There have been calls for people to stop eating wild animals. However, the danger is not just in eating them, but also in touching them. Keeping wild animals as pets or selling parts of their bodies as animal products also create risks for humans. Some wild animals were sold in Huanan Seafood Market.
