Aha. The place that the pre-symptomatic contagiousness was noted has been removed from the website, but was originally found at
While that page no longer exists, it was, while it was up, cited by many other websites. If you google this phrase:
cdc-changes-criteria-for-ebola-transmission-admits-being-within-3-feet-or-in-same-room-can-cause-infection
which was basically the name of the page, you will find a host of reputable sites pointing to this page. So what happened? Was the original posting in error, and removed? Or was I removed for other (politically correct) reasons?

I Googled that phrase, and all that comes up are a bunch of conspiracy sites (which really don’t interest me). I did go to one, and it had a screenshot from the CDC, which supposedly showed something that the CDC later “hid” by removing that particular page. Since that one site had screenshotted the CDC web page, I looked at it and compared to what is currently posted on the CDC. The page was edited and rearranged, but the information there is identical.
Despite the supposed conspiracy and “admission” that Ebola is suspected to transmit through droplets—which has been suspected for decades, and so hardly is a new “admission”—I do not see anything on any page that contradicts anything I know about Ebola.
Every single medical journal article I have read says that Ebola is only transmissible when symptoms appear, and that it becomes more transmissible as symptoms worsen. It can remain infectious in certain compartmentalized fluids for weeks after infection, but will eventually clear.
