Jigger Facts:
1. Jiggers are parasites that are recognized by many names, including the Tunga penetrans, sand flea, chigoe flea, pique, and bicho-do-pe. Jiggers should not be confused with chiggers.
2. Jiggers are the world’s smallest fleas, measuring less than 1mm in length, but they can swell to over 1,000 times their size when feeding and laying eggs.
3. The first recorded case of jiggers dates back to the early 1500s, when jiggers wreaked havoc on the crewmen aboard Christopher Columbus’ Santa Maria when they became shipwrecked on Haiti.
4. The Thomas Mitchell ship is infamous for transporting jiggers to Africa in the late 19th century. The outbreak started in Angola around 1872 and by 1924 jiggers had invaded Uganda, Kenya, Malawi, Mozambique, Sudan, and Madagascar.
5. Jiggers thrive in warm, dry, and sandy climates such as beaches, deserts, and areas with lots of dirt or dust.
6. Unlike most fleas, Jiggers are not very good at jumping. On average they can jump only 8–15 inches, making feet their easiest target. Other areas of the body are susceptible to jiggers if an individual sleeps, sits, or crawls on the dusty ground.
7. The fertilized female jigger is responsible for burrowing into the skin of an unsuspecting host. She burrows her small head into the flesh, working her way deeper and deeper until she reaches a blood source to feed on.
8. She will feed and grow for up to 2 weeks, continuously laying eggs over the duration of her invasion.
