What is the biggest economic threat related to coronavirus?

The the economy depends on supply and demand. The coronavirus has shrunk demand in most sectors therefore there is an over abundance of certain supply that people are not buying. Additionally, fear has impacted the economy especially when certain governments enact shelter in place orders that reduce the demand of consumers.

Explanation:

I also believe that fear is a major economic impact because of the increased risk of death with this virus and how virulent this virus is.

This is all related to the fact that this coronavirus is novel, which means new. It has never been studied and thus increases fear.
