This week Trending delves into one specific viral post. It's a list of supposed facts about the virus and what you can do to protect yourself. Some of the tips are true, some are false but relatively harmless, and some are potentially dangerous.

The list was first put on Facebook in early February and has since been dubbed the "uncle with master's" degree post, because of the alleged source of the information.

It hopped from Singapore to India to England and has been sent to us by listeners all around the world who are rightfully suspicious of its contents. Along the way it mutated - it has incorporated new and more dangerous false information, and has been translated into at least half a dozen languages.

So who's behind the post and how did it spread? We get to the bottom of this mystery. And we give some crucial pointers about how you can avoid spreading bad information.
