Abstract: This paper reports the diagnosis and treatment process of a patient with severe anemia caused by hookworm and Ascaris lumbricoides co⁃infections, so as to provide insights into clinical diagnosis and treatment and avoid misdiagnosis and underdiagnosis of parasitic infections. Living parasites were found by endoscopy, which were morphologically identified as hookworm and A. lumbricoides, and routine stool examinations detected hookworm and A. lumbricoides eggs. The patient was diagnosed with severe anemia caused by hookworm and A. lumbricoides co⁃infections by means of clinical symptoms, epidemiological history, endoscopic findings, and laboratory tests. Following blood transfusion, hemostasis, oral administration with albendazole, and symptomatic treatments, the patient showed remarkable symptomatic improvement and had a good prognosis.
