Not everyone has the exact same effect. Depends on various circumstances. It’s a shot in the dark how pneumonia will affect someone. Can be very serious, but can be very easy, too.
Your right about varying degrees of pneumonia. Even though the term “walking pneumonia” can be misleading. I’m going by the fact that she was so weak she had to be helped to walk then fainted. Then a few hours later she’s outside telling reporters what a nice day it was. If she had pneumonia bad enough that she was fainting, couldn’t walk from weakness, she would be in the hospital getting IV antibiotics.
I don’t believe she has pneumonia.
