Helminthiasis. Tips for getting rid of unwelcome guests

Helminthic parasites usually cause uncomplicated infections of the intestine. Complications can arise from nutritional competition between parasite and host, mechanical obstruction of the intestine or common bile duct (in ascariasis), and an overwhelming, fatal infection among immunocompromised hosts (in strongyloidiasis). Diagnosis is made by testing stool samples, except for Enterobius, which can often be seen in the perianal area. Treatment in uncomplicated cases is straightforward and easy. Several drugs are available, and the regimen depends on which parasites are present. However, none is safe for use in pregnant women.
