2019-nCoV There is a new and famous disease in the world. Actually, it's a little bit scary when something tiny threaten millions of people. It's not an alien or a secret weapon, it's just a virus similar to others virus we have dealed with succesfully before. There are many people infected and several (more than one thousand) have died because of it. Is it a big number? I don't know. Traditional flu kills thousands of people in every country every year. Why are we worried about this? Probably because we don't know how long it's going to spread around the world for example. The death rate is about 2.1%, not very big but we are very sensitive and probably too fearful. Good luck for everyone.
