時事新試用 Kre New Coronavirus Lisa Elmer CIDRAP News Feb. 10, 2020 The new Coronavirus (Covid-19) hit China at the end of December 2019. The virus first appeared at a market in Wuhan. So far, there are 40,000 cases and 910 deaths all over the world. That means the Covid-19 killed more people than SARS in 2002 and 2003. Coronaviruses are a large group of viruses, and infections are common in animals. Scientists think that bats might be hosts for viruses, and then the viruses jumped to other animals and people. After people ate the animals, they started to get sick. The early sign of the infections is having a fever. Then, like the common cold, people spread the virus by coughing and touching. Because it is a new virus, there is no vaccine or medicine to treat it, and few scientists know ways to stop Covid-19 from making more people sick. To slow the spread of infections, we had better put the following into practice. First, wash our hands often and for at least 20 seconds. Second, wear a face mask when you go to the hospital. Third, cover your mouth and nose when you cough. Finally, stay home if you're sick. virus is infection 1 host a spread 散布 vaccine
