Sarcoptic mange! Yuck!!! The very word sends creepy crawling shivers up the backs of many people. I’m getting the “itchies” just sitting here typing the word!!! Mange, specifically sarcoptic mange (there are a couple of other varieties), is nothing more than an infection by a tiny mite called Sarcoptic scabiei. These mites are so small, you could put a hundred of them on the head of a pin. I see probably fifty or more cases of the disease in dogs every year. The hallmark sign of the disease is intense, skin-ripping, non-stop, puritis (itching.) It is easily confused with fleas and/or allergies.
In humans, this disease is called Scabies. (As an interesting aside, the word scabies comes from the Latin word “to scratch” (scabere). The disease occurs world wide.
Our dogs, and rarely cats, catch the disease by coming into intimate contact with another animal who has the disease. In just about every case of mange I see here in upstate New York, there is a history of the pet having contact with a fox in the previous six months. Humans catch the disease by a similar exposure or they get it from their infected pet. (Horses, cattle and pigs also can have mange.)
We are lucky in this modern age to have very effective and safe treatments for this disease. I use a drug originally made for fleas and heart worm prevention called Revolution™ to kill the mites internally. (It is important that a dog or cat be tested and is negative for heartworm disease before using Revolution.) In my practice, I also give a cortisone shot to provide the misfortunate animal with some relief from their relentless itching. Less commonly used, but widely available worldwide, are lime sulfur dips.
My two-legged clients I send to see their family physician. A very comprehensive article on human scabies and treatment can be found at http://en.wikipedia.org/wiki/Scabies
