Many are familiar with fleas on their dogs and cats. In ages past, fleas caused plague and typhus, killing millions. Bubonic plague has started to spread again in the world, starting in Ankasina, Madagascar's capital. As of December 2014 there have been more than 126 cases and 47 deaths. Most of the people from Madagascar, the large island off Africa, died from the bubonic form of plague. They contracted it after being bitten by a rat flea that had contracted the bacteria from the rodents. Each year, the World Health Organization (WHO) receives reports of 1,000 to 2,000 cases. Between 1900 and 2010, there were 999 "confirmed or probable" cases in the US. Not many have heard of it since Ebola has captured the attention of the world. But sylvatic (occurring in wildlife) plague occurs in small numbers every year.
The Origin and "Discovery" of the Flea
Among the "creeping things" God created in Genesis 1:24–25 are countless forms of insects, including fleas.
We tend to think of them as repulsive pests, but they were created with good purposes and reveal creative diversity, design, wisdom, and the glory of God just as clearly as the fearfully and wonderfully designed human body. The ability to leap or jump is an awesome testimony of elegantly engineered, multifaceted design. They were most likely created as plant eaters to help with the recycling of leafy organic matter and detritus as flea larvae do today.
