Number 2 on the Wikipedia Gross-Stuff-You-Catch list, although I'm starting to think it's not really in order of seriousness. TB?! T?! B!?
So, Dengue Fever. It's caused by a virus transmitted by a mosquito found in the tropics. This doozy begins with high fever, chills and aching bones, accompanied by sore throat and depression. That's a mixed bag if there ever was one. Could be malaria. Could be flu.
Then, you get a skin eruption (isn't it wonderful how medical books use such descriptive words!? - Andy) that starts on the hands and feet and spreads to the rest of the body. Maybe, if you're very unlucky, followed by desquamation (mmmm, skin peeling off).
If you're even unluckier and you catch the one variant you begin to bleed and bleed and bleed and bleed. And bleed. Luckily, most times it's not fatal because your doctor will top you up with a couple of pints (blood, that is) and the disease will heal over a period.
And if you weren't convinced about the popularity of this cretin. There's even a band!
They make music that's both familiar, yet eerily unique. Apparently. Visit their site here!
