I've not watched this, but the picture reminds me very much of someone I saw in Little India, Singapore about 2 years ago, although they were not as severely deformed as the person in this story. Since then I've often hoped they were in Sigapore for treatment and not someone simply abandoned to their own fate by that wealthy nation.

This surely has to be a fake. I mean, how did the scammers get the sheep out of Australia? There are strict laws regarding the export of livestock, and I'm sure it would be equally difficult to get them into Japan too.
SMH and all the others reporting, you've been pwned!

Only 5 reasons? I'm sure there's many more that could be added, for instance here in Australia we have the Ross River and Barmah Forest viruses, both transmitted by mosquitoes. I've had Ross River virus and I can assure you that it's no fun at all.

Also there is increasing evidence that the Bairnsdale ulcer or Buruli ulcer is mosquito borne, this link has details, beware the pictures at the end of the page are not for the weak of stomach.
