Aping Jane Goodall: insights into human lymphatic filariasis.
The relationship between infection and disease has been a subject of intense debate in human filariasis. Most patients with chronic disease such as lymphedema or elephantiasis are free of demonstrable current infection. Based on cross-sectional data and a few assumptions and presumptions, two models of natural history of filariasis have been in vogue during the past two decades. The only (but arduous) way to understand the sequence of events is to follow up subjects with and without patent infections over a period of several years. This article offers critical comments and highlights the insights acquired from such studies.
