Harm of intestinal parasitic diseases

There are four kinds of intestinal parasites parasitic on human body, roundworm, hookworm, whipworm and pinworm. Various parasites can cause many kinds of harm to human body: Ascaris mainly absorbs nutrients such as digested or semi-digested food in the intestine; Hookworm specially absorbs human intestinal blood, causing many ulcers and bleeding on the intestinal wall; The head of Trichinella spiralis penetrates into the intestinal mucosa and absorbs intestinal tissue fluid and blood, causing congestion and edema of the intestinal wall; Enterobius vermicularis often lays eggs in anus at night, causing inflammation of anal pruritus and perineum. In addition, the parasitism and stimulation of worms can still cause pain and diarrhea around umbilicus and upper abdomen; Repeated infections in children can cause malnutrition, anemia, stunting, mental retardation and other hazards; The toxins and excreta secreted by worms are toxic and allergenic to human body, which can lead to fidgety, insomnia, urticaria, asthma, children grinding their teeth at night, night terrors, eating raw rice, dirt and other phenomena. Severe infection with ascaris can cause intestinal obstruction, biliary ascariasis, ascaris appendicitis and so on. It's really bugs that do great harm.

Parasites lay eggs in human intestines, and eggs are discharged with feces to pollute soil and food. Healthy people are infected by eating vegetables, fruits and drinking water contaminated by eggs, children sucking contaminated fingers, working in farmland, and direct contact between hands and feet and soil contaminated by eggs in daily life.

In order to prevent parasitic infection, we should strengthen health education, put forward a high awareness of personal protection, develop good personal hygiene habits, wash our hands before and after meals, do not eat unclean fruits and vegetables, avoid direct contact between hands and feet, and advocate wearing shoes to work in the fields. In addition, feces management, no defecation, etc. , can prevent the spread of eggs.
