I think I had it in the beginning of the month before my state was testing. Had a BAD respiratory virus, but I had albuterol inhalers, hot tea, and was a little active (being a mom). I think not laying around helps the lungs.
Also, my diet is rich in Zinc -- I eat a lot of eggs, beans, peas, etc... so it probably helped me, however, I still have "something".....
I may go get evaluated for a sinus infection or at least track down this random fever. I just hate going to the doctor because I often pick up something else while I'm there.
