"Some of the most common travelers illnesses include heatstroke, sunburn, diarrhea, giardia, cuts and bites.
Diarrhea
Diarrhea strikes many a first time traveler in developing countries. Those traveling from extremely clean environments or who have not traveled widely may react to bacteria, even harmless bacteria, in developing countries like Ghana.
Alternatively, water-borne diseases like Giardia can also cause diarrhea, but the symptoms are usually much more severe. Giardia symptoms include painful abdominal cramps, smelly gas and diarrhea. Giardia, like typhoid, is treated with a course of cipro.
