Its' the worst flu we haven't seen and don't want to see.
Whatever the recent cold/flu/bug that is going around the west coast is also going around Ohio and Florida.
People never really seem to get over it, it merely hibernates, incubates, and returns after 2-3 weeks.
Most people we know are on the 3rd to 4th run, each time making its presence known for about 2-3 wks with post nasal drip and sinus congestion. We first got it in Feb and are now wrapping up a 3rd comeback.
Those who have had it five times believe it peters out about then.
