Tungiasis: imported disease

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.

A case of imported tungiasis in Scotland initially mimicking verrucae vulgaris

A case is described of Tunga penetrans infection in the feet of a tourist returning from South America to Scotland. The condition had initially mimicked verrucae vulgaris, but microscopic examination of the lesions together with the travel history allowed the diagnosis of tungiasis to be made. This is the first case reported in Scotland.

Tungiasis: report of one case and review of the 14 reported cases in the United States

Tungiasis is a cutaneous parasitic infestation by the fertilized female sand flea Tunga penetrans. It is prevalent in tropical Africa and in Central and South America. Despite increasing air travel to and from these countries, surprisingly the disease is rarely reported in the United States. This report describes another case of tungiasis and reviews the 14 previously reported cases in the United States. Clinical features, differential diagnosis, treatment, and prophylaxis of tungiasis are discussed.
