The main carriers of this disease are Tunga penetrans that are better known as the burrowing flea or chigger flea. Their most targetted body part is the feet. The fleas anchor themselves into the skin then burrows into the layers of the skin through the epidermis. 

These are mostly found in tropical regions or deserts. Therefore, people are generally advised to wear shoes while walking on the sand so that they can not affect you. 


 Murine Typhus

Murine Typhus is a type of bacteria that is found in the feces of the fleas. Bugs bite and defecate at the same time, and that is when they transmit this harmful disease into the human system. The bacteria enter the body either through the bite wound or due to scratching done over the bitten area. 

Headache, nausea, fever, and body aches indicate the presence of this disease in your body.
