Hookworm dermatitis, also known as fecal contact, fecal toxicity, and ground itch rash, is a local inflammation caused by the burrowing of the duodenal hookworm or American hookworm into the skin. It usually invades the skin through hair follicles, sweat gland pores or thin skin areas, and then causes an acute inflammatory reaction at the site of burrowing. The hookworms secrete a hyaluronic acid that dissolves keratin, collagen and elastin, damaging the skin to penetrate the hair follicle. While using drugs to treat the condition, it is also important to pay attention to the diet and not to eat indiscriminately, otherwise it will aggravate the condition and cause other symptoms. Forbidden foods: 1. Milk and eggs. Milk and eggs play an important role in food allergies, and the number of patients allergic to these two foods is not only large, but most of them are in serious condition, and deaths due to allergies are common.

Compared with eggs and milk above, this group of food allergies is not common in China, which may be related to the Chinese people’s habit of eating meat or poultry after a long time of steaming.
