Tungiasis: more than an exotic nuisance.
Tungiasis is a parasitic and zoonotic skin disease caused by the sand flea Tunga penetrans-also called the jigger flea, which burrows into human skin, usually on the feet. The ectoparasitosis occurs in many economically depressed communities in the Caribbean, South America and Africa, and affects sporadically travellers to endemic areas. Usually, only one or two lesions are found in travellers, whereas the local populations commonly harbour dozens, sometimes even hundreds of lesions, associated with severe morbidity. We review case reports of tungiasis in returned travellers in terms of history, epidemiological and clinical aspects, and the importance of the ectoparasitosis for travel medicine is discussed. It is concluded that tungiasis is more than merely an exotic nuisance, since it is an important health problem in endemic areas. Untrained dermatologists can diagnose and treat tungiasis properly; fleas should be extracted as early as possible to avoid secondary infections.
