After Your Return: What's that spot on my skin?
One of the commonest things travellers bring back are skin rashes – dots, spots, ulcers, etc. Most commonly, these are from insect bites – mosquitoes, sandflies, bedbugs, fleas, etc. However, a few skin rashes are instantly recognizable, by someone who has seen them before. Here are a few.
|This is the eschar from a tick bite, which is usually picked up in the game parks of southern Africa. If you have this, you may also have a fever, headache and aches and pains. See a doctor!|
|This is the winding/serpiginous rash of cutaneous larva migrans. This is acquired by walking or lying barefoot in areas where dogs have left there poop! It is treated with the drug albendazole. I suppose you could find it on any tropical beach. I have seen it most often from Jamaica and the Barbados.|
|This looks like just a bunch of bites. Not sure who did the biting!|
|This is a fairly innocent looking bump, which looks like a boil. But the lucky person hosting this larva probably feels as if there is something moving inside. This is myiasis, an infestation by a botfly. This one I see mostly in people who return from the rainforests of Belize. To see the dramatic removal of this larva, go to YouTube!

|This rash resembles a mild burn, sort of in a streaky pattern. It is called phytophotodermatitis, which means you have probably accidentally rubbed some of your lime onto your skin. A substance in the lime juice reacts with the sunlight to give this rash. It goes away on its own. Gin and tonic drinkers beware.|
