Society is fragile and could very easily collapse. There are many evil thugs who would love the opportunity to take your stuff and/or harm you. Consider the riots and looting that occur after a natural disaster or court case that didn't go the way some wanted it to.
If the food really runs short, it could get nasty. It's not the virus I fear; it's people.
