The media isn't scaring the heck out of people. It is to get people to act appropriately given the lack of information. It is 10x deadlier than the flu right now, there is insufficient testing in the U.S. to determine the extent of the spread, and for some population, it is much deadlier.
Sure, we could just not care and the vast majority of the population will actually be OK. However, you would be sacrificing the vast majority of those with compromised immune systems, those with respiratory issues, and those over the age of 70.
If you want to blame people for causing the hysteria, blame 1.) The government for not developing and providing enough testing; 2.) The hoarders (I'm not talking about the common folk), but those who deliberately went shop to shop to purchase all of the masks/santiation materials to deliberately sell at huge markups on
amazon/eBay; and 3.) The business owners who did not react by instituting rationing measures.
