Interesting to hear that it's so highly contagious. Makes me wonder if I simply caught it a couple of months ago from my father, who developed pneumonia during his visit. Or I gave him pneumonia...
If I got it from him, this would make it less likely that the cause of my cough etc years back was the Mpn. Same with the MS.
When reading up on Cpn I saw that it has to be droplet infection, i.e. breathing the same air is not enough.
I know the prevalence of Mpn to be aroun 1/140 in the US.
Does anybody have rough figures for the prevalence of Cpn?
