How often children should be given roundworm shots needs to be determined on a case-by-case basis and should be analyzed on a problem-by-problem basis, not as a generalization. In general, children over two weeks of age can take roundworm deworming medication orally. If the child does not show obvious symptoms such as abdominal discomfort, malnutrition, anemia and emaciation, it is sufficient to take roundworm repellent medication once a year, and it is recommended to take it in autumn for the best deworming effect. If the child is diagnosed with roundworm disease, he or she needs to follow the doctor’s prescription for roundworm treatment, generally using broad-spectrum, high-efficiency and low-toxicity drugs, and children under two years old can be treated with pagoda sugar. Severe infections require multiple courses of treatment, the number of which varies from person to person. In daily life, parents should pay attention to avoiding their children from sucking their fingers after crawling on the floor, and develop the good habit of washing hands regularly before and after meals. In addition, the diet needs to be handled separately from raw food and cooked food.
