Adults are unlikely to get roundworm disease. Ascariasis is mainly caused by unclean eating and drinking, and its clinical manifestations are varied, which can be further treated by seeking medical advice to clarify the cause of the disease. Ascariasis is mainly caused by eating food or water containing roundworm eggs. Ascaris lumbricoides is mainly parasitized in the intestinal tract, and can be further transmitted by expelling the eggs from the body. Most of the patients have no obvious clinical manifestations after being infected with roundworm disease, while a few may manifest abdominal pain, fever, urticaria and other conditions, which may lead to loss of appetite, roundworm intestinal obstruction, etc., and even life-threatening in serious cases. The cause of the disease can be further clarified through stool examination, abdominal ultrasound, etc. Oral anthelmintics, such as albendazole, can be taken as prescribed by the doctor, and usually the prognosis of the disease is good, but a few can cause complications.
