Overview
Löffler syndrome is due to intestinal helminth infections with a pulmonary cycle which is distributed worldwide; nonetheless, parasitic infections such as Ancylostoma duodenale, Ascaris lumbricoides, Ascaris suum, Necator americanus, Strongyloides stercoralis are more prevalent in tropical areas particularly in communities with low socioeconomic status and poor sanitary conditions. In the United States, 20-67% of children in rural southern communities have been reported to suffer from ascariasis; Nevertheless, there are no specific statistics for the occurrence of Löffler syndrome. Globalization increased immigration, and travel warrants alertness of US physicians and the other health care works of developed countries, because an encounter with imported tropical diseases and thus the resulted Löffler syndrome could be more likely nowadays.
