I think it is Ascaris, not Stringlyloides. The symptoms could be explained by Loeffler syndrome, caused by Ascaris larva migration. Ascaris is transmitted through fecal oral route, so ingestion of feces contaminated soil could cause the problem. Per FA, Strongylides is transmitted by larva penetrating skin.

Its Ascaris. Fecal oral transmission -> Larvae penitrate GIT -> Blood Stream -> Lung {Maturation, Respiratory Symptom} -> Coughed up and swallowing -> Adult Warm in GIT -> Egg release -> Egg in stool.

Didn't the stem mention that roundwarm larvae were found? I thought Ascaris is diagnosed by bile coated eggs in feces?

I actually think @cassdawg is right. Its strongyloides. They found larvae in the feces (you find eggs in feces with ascaris) you can get pulmonary sx in both. Ascaris is also usually fecal oral transmission so its more likely to come from someone making food with contaminated hands. Strongyloides is transmitted through soil or sand and the larvae penetrate your feet so this makes more sense.

You can find this is FA 2020 Pg 159. Also if you look at the table strongyloides is assoc. with pulmonary sx. However I think its both cause according to sketchy micro ascaris presents with respiratory sx

Although Strongyloides nematode worm infections are not overly common in the United States, the Appalachian area of the Southeast have reported cases.
Ascaris lumbricoides is a common parasitic infection in Asia, Africa, and South America. Most cases in the United States arise in travelers to these regions.
Loeffler syndrome can be caused by Strongyloides and Ascaris.
Ascar:Stool microscopy reveals an oval egg with a thick outer shell and a single interior ovum
Strongyloides:rhabditiform larvae seen in feces under microscope
so.I think this is Strongyloides.If I make a mistake,please correct me.

I think is ascaris lumbricoides also due to the size of the larva. UW Q 15549

Definitive diagnosis of toxocariasis is larvae in stool. It definitely makes more sense than Strongyloides, which is found in the soil but PE found no abnormalities. So skin puncture is unlikely. Ascaris is fecal-oral but is more likely to be in contaminated food and is largely asymptomatic. Also, Ascaris would show eggs in feces, not larvae.

I think this is Strongyloides stercoralis (threadworm) is a roundworm whose larvae live in soil and who can cause pulmonary disease. It has the ability to penetrate skin from the soil but can also be obtained by ingesting feces contaminates soil (FA2020 p159) https://www.cdc.gov/parasites/strongyloides/gen_info/faqs.html
Most intestinal roundworms are fecal-oral route except strongyloides which can also penetrate skin, hookworm (necator americanus) which only penetrates skin, and trichinella which can come from undercooked meats (especially pork) but whose symptoms do not match that of the patient. Trichinella larvae enter the blood stream and infect muscle and can also cause trichinosis with fever, nausea, vomiting, periorbital edema, and myalgia.
