  • What Is the Prognosis? With proper treatment, children fully recover from ascariasis. Prevention Reinfection is common. Keep your child away from soil that could be contaminated with human feces.[healthychildren.org]
  • Treatment and prognosis Treatment with oral administration of a single 400 mg dose of albendazole is usually successful. In the presence of bowel obstruction, surgery is usually indicated. Promoted articles (advertising)[radiopaedia.org]
  • Prognosis [ 5 ] Uncomplicated infections respond well to treatment with anthelmintics. Left untreated, some infections will resolve spontaneously and adult worms usually cause little pathology if they remain in the small intestine.[patient.info]


  • This syndrome has been related to the group of disorders characterized by eosinophilia and pulmonary changes which include Löffler's syndrome 2 and tropical eosinophilia. 3 The etiologic basis of this syndrome has not been proved, but it has been assumed[jamanetwork.com]
