Strongyloides hyperinfection in Ethiopian immigrants in Israel.

We report four cases of Strongyloides hyperinfection among Ethiopian immigrants, of which three were fatal. Many immigrants from countries in which Strongyloides is endemic settle in developed countries. A high index of suspicion will lead to earlier diagnosis and treatment of this disease. Testing for Strongyloides infestation in this susceptible population by enzyme-linked immunosorbent assay serology, stool testing or duodenal aspiration may prevent the fatal complications of hyperinfection.
