Description

Strongyloidiasis is caused by parasitic nematodes (roundworms) of the genus Strongyloides and is considered to be one of the most neglected of the neglected tropical diseases (NTDs). There are two main Strongyloides species that cause human infection; S. stercoralis and S. fuelleborni. In Australia, S. stercoralis is the infecting species that disproportionately affects remote Indigenous communities, with the prevalence ranging from 10-60%. The lifecycle and transmission is complex with both a parasitic cycle and a free-living cycle. This is further complicated by autoinfection and the possibility of zoonotic transmission– recent genetic evidence suggests the possibility of a dog reservoir. These factors coupled with less than ideal diagnostics and treatment options (Ivermectin and Albendazole) where there is evidence of treatment failures, the spectre of emerging resistance and their inability to prevent reinfection, all have implications for control and elimination efforts. It is our central thesis that strongyloidiasis is a zoonotic neglected tropical disease of public health importance in Australia and that an integrated interdisciplinary “One Health” approach is required for its elimination.
