Coronovirus can be very serious, at its worse,it can shut down your kidneys and kill you. Since it just leap to humans from animals, we have no natural immunity. China thinks this is serious. China have isolated a whole province... shut down businesses, schools, and travel which is not good for their economy. I'm glad the WHO is being proactive. It is a serious health threat right now mostly contained to China. But with our global travel, it is better to be vigilant. And yes, I know the flu kills a lot of people each year.
