Actually I don’t believe Pneumonia is contagious. There are various different forms and some are causes by a virus and some by bacteria.
And not, I don’t believe she has Pneumonia, but a pretty masterful stroke by her campaign. Basically gets her off the hook medically until after the election. Anything that happens will be blamed on the Pneumonia.

There is viral pneumonia and bacterial pneumonia and they are both contagious.
