Tropical Disease

Tropical Disease

Tropical diseases are diseases that are prevalent in or unique to tropical and subtropical regions. The diseases are less prevalent in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation. Insects such as mosquitoes and flies are by far the most common disease carrier, or vector. These insects may carry a parasite, bacterium or virus that is infectious to humans and animals. Most often disease is transmitted by an insect "bite", which causes transmission of the infectious agent through subcutaneous blood exchange. Vaccines are not available for any of the diseases listed here, and many do not have cures.

Human exploration of tropical rainforests, deforestation, rising immigration and increased international air travel and other tourism to tropical regions has led to an increased incidence of such diseases.

Famous quotes containing the words tropical and/or disease:

“Oh, you’ll love the sea. There’s something about it. The hot red dawn, the towering sails, the wake on a tropical night. Oh, you’ll love it all. It’s a glorious kind of world. I couldn’t live without it.”
—Charles Larkworthy. Denison Clift. Capt. Benjamin Briggs (Arthur Margetson)

“Perfect Scepticisme ... is a disease incurable, and a thing rather to be pitied or laughed at, then seriously opposed. For when a man is so fugitive and unsettled that he will not stand to the verdict of his own Faculties, one can no more fasten any thing upon him, than he can write in the water, or tye knots in the wind.”
—Henry More (1614–1687)
