Your probably talking about Nector americanus, which is a hookworm with
infection acquired through skin penetration of the filariform larvae
from the soil on the farm. 

Okay, are you ready to be really grossed out??? Here is what is

After skin penetration, the larvae is carried to the right heart and
then to the lungs and migrate from the bronchi to the trachea and
pharynx, then swallowed and reside in the small intestines. Ooooo, just
thinking about ... well, not a pleasant story! Anyways, the worm
attaches itself to the mucosal lining and lives there for up to 15
years. The female worm begins laying eggs about 5 months after
attachment, which end up in the stool and possibly infecting others if
they are not careful! 

Diseases that can result from this infection:

necrosis of intestinal tissue
blood loss
abdominal pain 
eosinophilia (certain type of wbc)
iron deficiency anemia
mental and physical retardation.

I hope your friends come through well with treatment. It can be a long
discouraging process to deal with!
