"Shoo Fly Don't Bother Me"
Most tropical diseases can be easily avoided, but more than likely you may not know what are considered to be tropical diseases.
Believe it or not the best way to avoid tropical diseases is by avoiding coming into contact with foreign bugs, or bugs that can easily transmit diseases. The main culprit; the mosquito. Once a mosquito lands on you, he bites you sucking your blood and injecting his own type of venom into your blood stream. But think about how many other people he has done the same thing to.
Malaria and many other tropical diseases are transmitted through bugs that have the same way of transmitting blood from person to person. Mosquitoes are not the only culprit, but the way in which blood travels from person to person via insect puts people at a higher risk of contracting a tropical disease.
