What does chegoe mean?
The chegoe is the chigoe flea, Tunga penetrans, the smallest known flea in the world and the only one that burrows permanently into its host's flesh. Found in tropical and subtropical regions of Central and South America, sub-Saharan Africa, and parts of Asia, the gravid female chegoe penetrates the skin — most often around the toenails, soles, or heels of people who walk barefoot — and remains embedded as her abdomen swells dramatically over one to two weeks. This produces an intensely itchy, painful nodule and, if untreated, can lead to secondary infection, ulceration, or loss of nails; the resulting condition is medically termed tungiasis. Removal requires careful extraction with a sterile needle, since rupturing the flea can cause serious infection. Though chiefly a technical or historical term today, "chegoe" appears frequently in travel writing, colonial-era accounts, and public-health literature about parasitic disease in the tropics.

"Medical workers in parts of Africa and South America treat infestations of the chegoe, which embeds itself in the skin between the toes."
Standard pluralization; the variant spelling "chigoe" takes the plural "chigoes".
"Barefoot children in the village were at constant risk of picking up chegoes."
The female chegoe flea burrows permanently into your skin and then swells to hundreds of times her original size — the only known insect that does so.

Etymology of chegoe
The word "chegoe" entered English in the late seventeenth century, borrowed through French or directly from a Caribbean source, reflecting the flea's presence in the West Indies when Europeans first encountered it there. It exists alongside numerous variant spellings, including "chigoe", "chigo", and "chega". The term is unrelated to "chigger", the North American name for the larvae of harvest mites, though the two words are frequently confused because of their similarity in sound and meaning.
How chegoe is actually used
"Chegoe" is one of several spellings (also "chigoe", "chigo", "chega") of a word most often encountered in medical, entomological, or historical writing about tropical regions. In everyday speech, the related terms "jigger" or "sand flea" are more common in some regions. The condition it causes is called tungiasis.
Easily confused with chegoe
A chigger is the larva of a harvest mite that causes itchy welts on the skin, whereas a chegoe (chigoe) is an actual flea that burrows into the flesh.
