I need a doctor for strongyloids?

Parasite: Human infection, strongyloidiasis, is chiefly caused by Strongyloides stercoralis, widespread in all tropical regions, or by Strongyloides fuelleborni, a parasite of primates in African and Asian tropics and humans in African tropics and New Guinea. Depending on what country you're in, you need to see a general practitioner familiar with local parasites or (in the USA), an infectious disease doc.

If you suffer from Strongyloides and live in the US, infectious disease doctors would likely be familiary with this.
