The two most common diseases are Edema and Metabolic Bone Disease (MBD). Improper food, lighting or supplementation causes both of these diseases. Should you ever suspect something is wrong with your chameleon immediately seek a reptile vet, or better yet one with considerable experience with chameleons.

Chameleons may also catch mites, worms or other types of parasites. There are a few methods of dealing with them but seeking a vet is the only real advice one could give. I cannot discuss cures for any of these as it may be completely different from one vet to the next, also I lack the experience in this area.

Most wild caught chameleons contain high parasite numbers. It is best to take a fecal sample into the vet for a parasite check (usually floated) to see if any medicinal action should be taken. Many keepers automatically treat newly acquired wild caught animals with a dewormer to be safe. This requires a little experience and careful measuring as to not overdose.

All new animals should be quarantined for 30 days or more whether you are introducing them to an existing enclosure or even in the same room as other animals. Your quarantine enclosure should have all of the essentials aside from being as large as permanent quarters. Wash your hands and equipment thoroughly before touching or working in another animals enclosure. Diseases and parasites can easily spread, so quarantine can easily reduce the risk of infecting all of your animals.
