Diva was diagnosed with a sinus infection. She has had body aches so I am sure she had the "flu" also. Now, we must realize that when someone says "Flu" (including me) it indicates flu-like symptoms. The medical field has a very different way of looking at this - it is NOT the flu but a virus in many many many cases. I saw difficult child's daycare provider today - haven't seen her in a long time. We caught up on difficult child and Diva. When I mentioned to her that Diva was very sick this week, she stated (and she is much more knowledgeable about these things than I am) that there is a nasty VIRUS going around that MIMICS the flu. This virus looks like the flu however usually turns into bronchitis, sinus infections, croup, whatever. That fits exactly with what Diva went through. She also stated that those who get the virus will be more susceptible to the real swine (sorry H1N1 for those medically correct) flu because their bodies have gotten so run down from the virus and the flu will make them even sicker. So those of you who are now sick, if you do not have the swine flu, be extra extra extra careful these next few months and through the winter - YOU can not afford to get the swine flu. It will be super nasty and if you have the virus like Diva, I know you will not want to be worse - nasty stuff! So, when to call the doctor? I would say by day 4 if there is no improvement CALL and talk to a nurse. Let them decide if you are at the point to be seen. However, if you have the virus that turns into croup, bronchitis, sinus infections, you will need to be seen ASAP to deal with that. So, if by day 2 or 3 you feel that something besides the flu is happening, call the doctor ASAP and for sure by day 4 if you are unable to control a fever. Everyone step up the hand cleansing - hand santitizers, encourage the kids to wash hands more often, teach kids how to sneeze into their elbow, ect. If you don't feel well, stay home and pamper yourself with lots of fluids and sleep. If you are not sure, go ahead and call a nurse or some people have an insurance help line or public health if you work with them. I heard it is hitting a population that is known to be healthier than others (like my 19 yr old diva) - those you would not expect to catch it so easily. Keep a close eyes on the infants - especially the newest ones.
