After penetrating the stratum corneum, they burrow into the stratum granulosum, with only their posterior ends exposed to the environment . The female fleas continue to feed and their abdomens extend up to about 1 cm. Females shed about 100 eggs over a two-week period, after which they die and are sloughed by the host's skin Tungiasis had been endemic in pre-Columbian Andean society for centuries before discovery of T. penetrans as native to the West Indies. The first case of tungiasis was described in 1526 by Gonzalo Fernández de Oviedo y Valdés , where he discussed the skin infection and its symptoms on crew members from Columbus's Santa Maria after they were shipwrecked on Haiti. [25 The data from before and after school holidays, whilst a small dataset, highlighted a number of findings that are significant and warrant replication in future. Not only did the overall prevalence of tungiasis increase after the holiday, there was also a significant increase in the number of manipulated lesions

Tungiasis is a tropical skin disease caused by the sand flea Tunga penetrans. It inflicts misery upon tens of millions of people, mostly children, across Central and South America and sub-Saharan Africa, and yet there is no globally accepted roadmap for its control. Here we review how research in the last 15 years has developed control methods and report on new grassroots and digital mapping. Tungiasis in humans was first reported in the years following 1500 AD, when sailors with Christopher Columbus suffered skin infections, after they were shipwrecked on an island of Haiti. Fleas responsible for tungiasis have limited jumping/flying abilities (<30 cm), and therefore most human lesions appear on the skin, below the waist, particularly on the legs
