TEXTH BIEXXIAL REPORT. ^ i 1 cause was not understood until about the middle of tlie nineteenth century, when it was shown to be due to an intestinal parasite, AgcliyJostoma duodenale. Until 1S93 no authentic cases of this disease were recognized as such in the United States, hut between 1S03 and 1902 about thirty-five cases were diagnosed. In 1902 it was shown that a distinct hook-worm, Lnelnaria americamty infests man in this country, and this indicated very strongly that the disease must be present although not generally recognized. It is now established that in addition to the few cases of Old World hook-worm disease imported into the United States, we have in the Soiith an endemic uncinariasis due to a distinct cause, Uncinaria americana. This disease has been known for years in the South, and can be traced in medical writings as far back as ISOS,* but its nature was not understood. Some cases have been confused with" malaria, others have been attributed to dirt-eating. The hook-worms are about half an inch long. They live in the small intestine, where they suck blood, produce minute hemorrhages, and in all probability also produce a substance which acts as a poison. They lay eggs, which cannot develop to maturity in the intestine. These ova escape with the fteces and hatch in about twenty-four hours; the young worm sheds its skin twice, and then is ready to infect man. Infection takes place through the mouth, either by the hands soiled with larvje or by infected food. Infection through the drinking water may possibly occur. Finally, the larvae may enter the body through the skin and eventually reach the small intestine. Patients may be divided into light cases, in which the symptoms are very obscure; medium cases, in which the anjemia is more or less marked, and severe cases, represented by the dwarfed, edematous, anjemic dirt-eater. Infection occurs chiefly in rural sand districts. Above the frost line the symptoms are more severe in summer than ■in winter, and whites appear to be more severely affected than negroes. Persons who come in contact with damp earth are more commonly infected than others ; so that the disease is foimd chiefly among farmers, miners, and brickmakers. Severe cases are more common in women and children than in men over twent^'-five years of age. Uncinariasis is a disease which occiu'S in groups of cases, and if one case is found in a family the chances are that other members of the same family are infected. The testimony of patients severely infected is unreliable. Recalling that any one or more symptoms may be absent or subject to variation, it may be noted that the period of incubation fat least before the malady can be diagnosed by finding the eggs) i^^ from four to ten *An article by Dr. Pitt, who says that "along the Roanoke River. N. C.. malaria or dirt-eating prevails, mostly among poor white people and negroes and originates, in my opinion, from a deficiency of nourishment."—Ed.
