I work in a diagnostic Virology lab and hate the thought of "Flu Season". Technically, Flu Season runs from Oct 1st to April 30 but as the years go by we are seeing the lines that define "Viral Seasons" blurring out of existence. Our "current" season is Enterovirus Season but it can mimic the symptoms of Influenza and/or the Parainfluenzas. And to our dismay, we have already seen positive Parainfluenza cultures this week. I hate flu season!
