The hookworm larva lives in infected soil, particularly in tropical climates and coal mines where it thrives in warm earth where temperatures are over 18°C. They exist primarily in sandy or loamy soil, and cannot live in clay or muck.
The larva clings to the intestinal mucous membrane and develops into an adult hookworm, drawing its nourishment from the blood-vessels of their host, and as the parasites are found in hundreds in the body after death, the disorders of digestion, the increasing anaemia and the consequent oedema and other cachectic symptoms are easily explained.
