Harm And Manifestation Of Ascariasis
Deprivation of nutrients
Worm infections can contribute to protein depletion. According to calculations in an experimental study in humans, in children infected with 13-40 worms lost about 4g of protein per day for a meal with 35-40g of protein. Dry form malnutrition is also associated with roundworm infection. Ascaris infection can contribute to a decrease in the amount of vitamin A and vitamin C. Children with night blindness recover quickly from eye symptoms after deworming
The moving worms can carry bacteria from the intestine to other places and it is hypothesized that the infection between roundworm and polio is related.
Many people infected with ascariasis have a sensitivity to the antigen of the roundworm and when the laboratory where the worm is operating is also sufficient to have conjunctivitis, urticaria and asthma. The skin of these patients is extremely sensitive to roundworm antigen at very small doses, they have immediate anaphylactic reactions, often manifested by itching and pink lesions
Most cases of roundworm infection usually do not have clinical manifestations, mild infections are often asymptomatic, but sometimes a single infection can cause liver abscess or shut down bile ducts. The acute symptoms correspond to the number of infected roundworms and severe symptoms may occur when the number of roundworms is in the hundreds.
Although reinfection can occur throughout life, it is possible to participate in reducing severe infections if immunization or exposure is reduced.
The incubation period starts from the time an egg is swallowed into the body until the egg begins to appear in the stool for 60-70 days. Lung symptoms due to larvae movement will appear on 4-16 days after infection.
Diseases caused by roundworm larvae
Pneumonia caused by roundworm larvae: during larval migration, pneumonia occurs on days 4 to 16 after being swallowed, symptoms include fever, cough, productive cough, and pulmonary infiltrates. Acute leukocyte (BCTT) is elevated and larvae can be found in sputum or in duodenal juice

.), eyelid edema or insomnia and gnashing of teeth at night. When the larvae stray to the brain, it causes granulomas, small nodules in the eye, retina or brain.
Disease caused by adult roundworm
In the intestinal tract: common symptoms of digestive disorders, enteritis and vomiting. If severe infection, manifested mainly by intestinal obstruction, usually occurs in children, there are cases of catching 100 roundworm in a patient
Outer intestine: caused by displaced worms: adult worms tend to move when their habitat is disturbed. Patients taking tetrachloroethylene, anesthetized or had a fever, moved and strayed into the bile ducts, Vater's balls, appendix, around the anus and the eustache tube. They can cause intestinal torsion and necrosis, intestinal perforation and peritonitis, acute pancreatitis, purulent bile duct inflammation, liver abscess, acute cholecystitis and obstructive jaundice.
Prevention is based on personal hygiene, hygienic handling, health education and treatment of infected people.
