Adults are also at risk for ascariasis. Adults are also susceptible to ascariasis, but the infection rate is higher in children than in adults, with the highest rate in preschool children. Ascariasis is infectious and is mainly transmitted through the fecal-oral route; the eggs of the roundworms can be excreted in the feces and then enter the human body through the mouth through contaminated soil, vegetables, fruits and melons, etc. The disease is caused by a worm-like nematode called Ascaris lumbricoides. Ascariasis is a chronic infectious disease caused by earthworm-like roundworm nematodes parasitized in the small intestine or other organs of the human body. The patient may not have obvious symptoms, or there may be nausea, vomiting, abdominal distension, diarrhea, loss of appetite and other symptoms. Ascariasis is usually treated with anthelmintic drugs, including mebendazole and albendazole. If the patient has the above symptoms, we need to consult the doctor in time and follow the doctor’s instructions for treatment, do not blindly self-medication.
