tape worms eggs can spread all over the cage so it needs to be de-wormed and the cage sterilized. I would make sure you wash your hands after touching anything in the cage.. Anywheres that the iguana's body touches can basically be considered contaminated. There are a few medications for tapeworms.. one is praziquantel I cannot remember the others (and I probably spelled that wrong). Dosage size and use I have no idea.
I see very few people here from your region of the world post here..
I found a facebook organization called "PAWS Kuwait" if you have a facebook account I'd try there. Also might want to try contacting www.kspath.org/
