Antischistosomal drugs inhibit egg-laying by adult worms. Therefore, patients’ stool and urine should be tested for 6 months after treatment. Treatment is repeated for those excreting eggs. If symptoms recur, hematuria occurs, or eosinophilia is noted, repeat parasite investigation should be performed. However, serology can remain positive for years.
