Closer examination of the worm (100x and 400x magnification) revealed a small spiked proboscis:

Is that D shaped egg for Enterobius vermicularis?
Looks like a case of acanthocephaliasis! Egg and adult seem to both resemble Moniliformis moniliformis.
agree with Malassezia, the probocis gives away its acanthocephalan identity and the morphology, size and the gross anatomy of the egg suggests M. moniliformis. The kid likely consumed a beetle or cockroach intermediate host to get infected. Nice unusual case!
in the last picture the devoloping cercarie looks like Schistosoma.
