An Unreported Plague?

Saw this post on Instapundit, repeated in full:

THE PLAGUE YEARS: Local schools have been closed because of flu since Thursday. The Insta-Wife has flu. The Insta-Daughter is just over it. (I'm okay, but taking Tamiflu as a preventive measure, since I have a trip planned later this week.) My classes are notably empty, and many of the students who are there are hacking, coughing and looking miserable.

It's February.

This is astonishing. What are workplaces like? Can anyone who lives in KnoxVegas send in reports? How bad is it altogether? I'm surprised this isn't being reported on the news.
