I have been warning here before that Ebola phishing attacks would be more and more prevalent, as a result of the mass-media spending increasing amounts of time covering this threat.
And sure enough, it was only a matter of time until you could see phishing and malware attacks using social engineering to trick users into clicking on links or opening attachments.
The US-CERT (United States Computer Emergency Readiness Team) has issued a warning about it, and they advise users to keep an eye out for fraudulent emails of this kind, in order to stay safe from malicious cyber campaigns.
I would use this CERT notification and send the link to your users. It's short, easy to understand, and it's official so it may make a bigger impression than normal.
Feel free to copy/paste/edit this blurb:
"I would like to alert you all of a recent increase in scams related to Ebola. Please double check anything you receive via email or see on social media related to Ebola, like emailed warnings, web-alerts, news updates and possibly even videos. The only way to get news about this is straight from a reputable source. Also, do not fall for fake websites that sollicit online donations for Ebola victims. Verify the site is legit before you donate anything. I have said it before and I am saying it again: "Think Before You Click!"
Here is an official message from the U.S. Government about Ebola scams:
