Great question, the short answer is worms live in the soil and soil can get warm... the worms lay eggs, the larvae hatch and move... they will seek conditions favorable for their survival. Aside from the CDC you may wish to consult the following website as they have more on this disease, complete with maps about the global soil distribution of this nematode (worm). http://www.infectionlandscapes.org/2012/03/strongyloidiasis.html
Thank you for your comment and Im hoping I can get just one more opinion from you if it's not too much trouble.Are theses horrible little things able to survive in a boarding kennel type environment given the right conditions? Say mid-summer, 85+degrees, no windows/ventilation, backed up open drainage system, etc? Just curious.
Your poor dog, for those of you unfamiliar with this beast, its a worm or more precisely approximately 40 different types of worms or nematodes that can infect a wide range of animals, including humans. It is principally transmitted through dirt as the free living larvae contact the skin, they penetrate and move their way through the animal. This parasite was first described by the French in the 19th century who were stationed in colonial Vietnam who were suffering from severe, persistent diarrhea. However, the principal presentation in people, is a localized pruritic (itching) red (erythematous) rash at the site of penetration by the worm. Some may develop a dry cough (tracheal irritation) as the wee beasties (larvae) migrate from lung up the throat where they are then swallowed resulting in what the French saw in colonial Vietnam (severe and persistent diarrhea). Good news today, for humans, we often don't know we are infected and thus have no symptoms, however, like the colonial French, some humans can become critically ill. The CDC (http://www.cdc.gov/parasites/strongyloides/) has great set of pictures with treatment options for people, with Ivermectin (200µg/kg (1-2 days) being the first line drug for both the acute and chronic forms of the disease. Your dog probably picked it up while being a dog. Playing and rolling in the dirt or burying bones is a prime risk factor of acquisition of the parasite. As to why after treatment no improvement? There is always the demon of resistance to drug, hypersensitivity to debris left by the dead parasite subsequent to treatment or even potentially re-infection. Your vet will be able to address such issues. Humans can protect themselves from infection by simply wearing shoes while interacting with potentially infested soils, as the worm is after all one of the unseen forms of life on our planet.
