Why do adults get nematodes?

Pinworms are roundworms in daily life. Pinworm disease is a typical parasitic infection. People with pinworm disease usually experience unbearable itching around the anus, indigestion, and teeth grinding at night. Children are the main patients of pinworm infection because they usually do not pay attention to personal hygiene. However, adults also have a high chance of contracting pinworm disease. So what are the causes and treatment methods for pinworm disease in adults?

1. Causes

1. Contact infection

People with pinworms are the only source of infection. The main ways of infection are direct infection through the anus, hands, mouth and contact between people. Occasionally, larvae incubated around the anus crawl back into the anus and cause retrograde infection. The disease is easily spread and often causes epidemics in collective institutions or families.

2. Bad hygiene habits

Many people do not have good hygiene habits, which makes it easy for them to be infected. For example, food and toys contaminated with insect eggs may be contagious.

3. Pathogenesis

The pathogenic effects of pinworms are multifaceted, mainly mechanical or chemical stimulation, nutritional consumption and complications caused by the loss of worms, which lead to corresponding clinical symptoms. Pinworms at different developmental stages in the host's intestines exert a certain degree of mechanical and chemical stimulation on the nerve endings of the intestinal wall, and can reflexively cause neurological and gastrointestinal dysfunction. The head of the adult worm drills into the intestinal mucosa to absorb nutrients from the host. It can also swallow intestinal contents and trace amounts of blood. If the number of pinworms is large, it can affect the nutritional absorption and physical development of children. The female worms lay eggs around the anus, which can irritate the skin and cause local itching, inflammation or local eczema, bleeding and secondary infection.

2. Countermeasures

1. Pinworm disease is closely related to the patient's living habits. Therefore, you should pay more attention to your diet. Diseases enter the body through the mouth. The food you eat should be hygienic. Do not eat raw or cold food, especially meat. There are many parasites in raw meat.

2. Patients with pinworm disease should pay attention to eating light food, mainly green vegetables, eat more fresh fruits and vegetables, try to supplement more vitamins, and eat more protein foods. Vegetables, especially fruits, should be washed before eating, so as to reduce bacteria.
