LOTS of flu here in MA, including my own son and husband. What I am noticing though, is there are still SO many people who say "I have the flu" but have not actually seen a doctor and been diagnosed with influenza. I have also had several parents say their kid had the flu, only to find out it was a GI bug that they were calling "The Flu". I even has a teacher come back after being out two days saying she was down and out with the flu. I asked her about symptoms, if she took Tamiflu, etc. and then she says "On I never went to the doctor and didn't have a fever, just threw up a few times".
I am sure there are several that had the "flu-like" illness that was not influenza, and several who had the flu who never got diagnosed...really hard to keep track around here.
