The efficacy of topical, oral and surgical interventions for the treatment of tungiasis: A systematic review of the literature.

<h4>Background</h4>Tungiasis is a neglected disease caused by Tunga penetrans that can be complicated by secondary infections and local tissue destruction. Adequate treatment is important, especially in vulnerable populations; potential treatment options proposed range from surgical extr...
