We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I have analyzed the above statement "Snopes says this story is false." and determined that it merits the rating "FALSE".
Snopes analyzes a fake photo which purports to be an x-ray showing a cockroach in someones chest cavity. They demonstrate that it was likely formed by 'shopping the cockroach image into an image of an x-ray that happens to be one of Marilyn Monroe's chest.
So what they declare to be "false" is the statement/story "An x-ray image shows a live cockroach in a patient's chest in Zimbabwe."
Our story above does not give us an x-ray image to debunk, and the soccer-star Matovu is said to have gone to Mulago hospital, which is not in Zimbabwe, but in Kampala Uganda.
Snopes does note "variations of this story have been circulating for several years." including a version from a joke compilation mentioning Ghana.
All of that said:
I do think this story if fake. With a sports star as internationally known as Matovu in a country with English-language press, if the story was true and leaked, or if Matovu had himself told it (whether as a joke or true) in a public forum or press interview, that would be searchable.
One of the things I've noted with Snopes -- for political stories that don't fit their world-view, they will find a straw-man version of the story to either "prove" (if it makes their opposition look bad) or "disprove" (if the canonical story makes their side look bad). So perhaps this is why I am predisposed to head right to the "claim" box on any Snopes article to discern whether the thing being marked "true" or "false" is actually what they intimate in the headline.
