How roundworms are infected, and will roundworm infections cause recurrent infections? How can I pre

Adult roundworms live in the small intestine of humans or other animals, most commonly in the jejunum, and feed on semi-digested food. After the female and male adults mate, the female lays eggs, and the eggs are excreted with the feces, polluting the environment, and the fertilized eggs are in shade, moist, oxygen-sufficient and suitable for the fertilized eggs of roundworms.

At a suitable temperature (21 30), after 2 weeks, the egg cells in it develop into the first stage larvae, and after another week, after the first molt in the egg, it develops into infected eggs. During the infected stage, the eggs are swallowed by the human body and the larvae hatch in the small intestine. The larvae can secrete hyaluronidase and protease, invade the mucosa and submucosa of the small intestine, burrow into the small veins or lymphatic vessels of the intestinal wall, enter the liver through the veins, and then pass through the right heart to the lungs, penetrate the capillaries into the alveoli, where the second and third molts are performed, and then migrate along the bronchi and trachea to the pharynx, swallowed by the host, through the esophagus, stomach to the small intestine, and develop into adult worms after several weeks after the fourth molt in the small intestine.

It takes about 2 months from the time the eggs enter the human body during the infection stage to the time when the female begins to lay eggs, and the adult worm lives for about 1 year.

Mainly through the mouth, eat food and water that is contaminated by insect eggs and have not been processed and cooked, or other things that are contaminated, such as children who like to eat hands, dishes and chopsticks, etc., if there is insect egg pollution, it will also be infected.

The above does not consider extreme situations, such as those female celebrities eating roundworms or something.

The oral route of infection is soil-based.

Diseases and insects, of course, come from the mouth.

The lifespan of roundworms is only l 2 years, if you are infected with roundworms without any **, as long as you do not repeat the infection, then after l 2 years roundworms will be eliminated by themselves. Conversely, if a child with ascariasis does not pay attention to hygiene after effective deworming, adult roundworms will reappear in the intestine after two months due to the presence of re-infected roundworm eggs. Therefore, the key to preventing ascariasis is to make the "disease from the mouth" pass, and the following points should be done

l) Teach children to wash their hands before eating and after using the toilet. When washing hands with a basin, there should not be too little water, and it is best to rinse directly with tap water. (2) Fruits and vegetables should be washed thoroughly, fruits should be milled and peeled, and raw tomatoes should be washed and scalded with boiling water before eating.

3) Teach children not to play on the ground as much as possible, such as playing, pinball, shuttlecock kicking, etc. Wash your hands and toys after playing. (4) Cut your nails frequently, and don't bite your nails.

Handkerchiefs should be washed every day, kept in clean pockets, preferably with napkins. (5) Eliminate flies and cockroaches, and do not eat food that has been stung by them. (6) Teach children not to drink raw water and not to defecate anywhere.

For pediatric ascariasis, a sufficient amount of anthelmintic drugs should be given according to age under the guidance of a doctor, and adult worms must be seen to be excreted from the body to be truly effective. If the dosage is too small, the roundworm cannot be beaten; If the dose is too large, it is easy to produce *** and even poisoning. Taking the anthelmintic drugs currently used is not as good as avoiding the mouth.

Generally, it is best to choose the time of taking the medicine before going to bed, which can reduce ***. If there are more deworms after deworming, it is necessary to confirm whether it has been expelled, and a laboratory test for stool concentration to find eggs can be done after a month, if you can't find the eggs, don't do it again. After taking anthelmintic drugs, no adult worms are discharged, and it is possible that the worms are small and wrapped in the stool and cannot be seen by the naked eye.

If the clinical symptoms improve, the abdominal pain disappears, the complexion turns red, and the appetite increases, you can observe the stool for a period of time to determine whether to continue the medication. Some children have roundworms discharged, there are still irregular abdominal pain, stool 2 3 times a day, this is a digestive disorder, can be treated with traditional Chinese medicine, so that the child can recover health as soon as possible. Deworming must be under the guidance of a doctor, do not deworm the baby privately, because if the baby is dewormed when the baby has abdominal pain, it may cause roundworms to run around in the abdomen, causing serious complications.

Pediatrics (roundworms) 20 raw pumpkin seeds, shelled and mashed, add brown sugar before meals to take in the air, eat it once, and the worms can be excreted with the stool the next day. Avoid greasy.

It will be caused, so in ordinary life, you should drink cold and white, and eat cooked food, never eat raw, usually pay more attention to hygiene and cleanliness, wash your hands before eating, and be clean enough when cooking.

It can be recurred. We must pay attention to the hygiene of the diet, pay attention to the hygiene of the living environment, flies and cockroaches must pay special attention, and they need to be eliminated immediately, so that infection can be avoided to a great extent.

Of course, there will be repeated infections, at this time we must eliminate the nearby source of infection, ensure that the surrounding environment is clean, when eating food, we must wash it, you can also soak it in salt water for a while before eating, you must pay attention to rest, and the usual diet should be kept light, do not eat some spicy and greasy food.

Such patients will be repeatedly infected if they do not pay attention to protection, and they must be washed when eating vegetables and fruits, and soaked in baking soda and salt for a while before eating, which will effectively avoid the production of roundworms.
