As concerns over the new coronavirus spread around the world, people have to make basic health decisions. They are wondering how worried they should be about getting infected and what they should do about it.

Some decision can have unexpected results however. For example, because of fears over getting infected, large numbers of people have bought masks to cover their faces. This led United States Surgeon General Dr. Jerome Adams to write this message on Twitter: "Seriously people – STOP BUYING MASKS"

He noted that masks are not effective in protecting the general public. The masks should be kept available for those who really need them. He added that "if healthcare providers can't get them to care for sick patients, it puts them and our communities at risk!"

It is hard to know just how concerned people should be. Someone who lives near an area with many reported cases of coronavirus may be right to be more concerned than someone who does not.

But experts note that people do not only make decisions based on calculations.There are also emotional and psychological influences that play a part.
