I must question how any agency keeps track of the cases of flu, colds, pneumonia or anything else. Doctors, maybe most Doctors, do not test for infections, they just treat the symptoms. It's been a month ago I was diagnosed with pnemonia. It was horrible, and I'm still recovering, but no tests were ever done to see what exactly I had or what caused the pneumonia. Was it the flu? A cold? Did I also have mono and/or strep throat? The symptoms are all the same. And while I was recovering, my wife came down with an awful cold or flu. She still has it. The Doctor prescribed a bag of medicines, but we'll never know what illness she actually had.
One person says he has a cold. The next person with identical symptoms says he has the flu. Maybe a feller has Legionnaires, Noro, Hanta, Ebola, or others. Mostly we never know. And then we have epidemics.
No matter what, a person can be quite miserable.
Get well!
