The treatment of uncinariasis may be considered under three headings: First, the prophylactic treatment, or that directed toward the prevention of infection by the hook-worm; second, the means used to cause the expulsion of the parasite; third, the treatment of the anemia and debility resulting from the infection.
Prophylaxis is of very great importance, and is a subject which requires careful consideration. It seems probable that infection takes place chiefly through the mouth, either in infected water or food, or through contaminated hands, which carry the parasite to the mouth. Looss, however, has apparently proven that the larvæ may penetrate the skin. A possible entrance through the air passages has also been suggested, but does not seem probable.
A most important fact, and one which greatly simplifies the treatment of uncinariasis, is that there is no increase in the number of parasites in the intestinal tract of the victim. Each
