My husband had it a year ago, but none of the rest of us got it... now my 11-year-old son has it. He's been congested and headachy for a few days; then today he became tired. He reported feeling "dizzy" earlier today, too; that's the symptom that got me to take him in. I thought it was maybe a sinus infection, but they tested him as a precaution, and, voila.
