Effects of nodulectomy in onchocerciasis in Ecuador.

Abstract

Nodulectomies were performed in a hypoendemic area on the Rio Santiago and in a hyperendemic area on the River Cayapas. All palpable nodules were removed. In the hypoendemic area the nodulectomies had a positive effect in reducing the intensity of infections and they contributed in the control of the advancement of the disease. In the hyperendemic area also a positive effect was observed but new nodules developed rapidly.
