Mange in dogs, is it contagious to humans?

by admin

As we discussed in the previous article, there are two main types of mange in dogs ; We have already talked about demodectic mange , today it is the turn of sarcoptic mange in dogs .

What is sarcoptic mange?

It  is a disease caused by a mite called Sarcoptes scabiei . The mite lives in the upper layers of the dog’s skin, where it burrows into tunnels and lays its eggs to reproduce. The clinical symptoms of this disease are due to the irritation caused by this activity, and in some cases to a hypersensitivity reaction (allergy) of the dog against mites. Sarcoptic mange or scabies affects dogs of all ages and breeds, although it is more common in young dogs. Due to this excavation of tunnels by the mite, the dog will present a very intense itching (pruritus) , this being the main symptom and the one that will cause the rest of these; since, being itchy, the dog will be scratching continuously causing self-injury. These lesions are erythemas, papules, excorations, ulcerations, scabs, and scaling. The distribution is usually generalized , although they are more intense in the ears and elbows .

How is msarcoptic ange diagnosed?

Unlike demodectic mange, sarcoptic mange is more difficult to detect . The vet can look for sarcoptic mange with a skin scraping, but it is very difficult to find it; In fact, it is said that in more than 50% of a sample from a dog with sarcoptic mange, it is not detected under a microscope. Another option for its diagnosis is, in the event that it is suspected due to the symptoms, treating the patient directly with an acaricide; if the disease disappears, there is evidence that it was mites that were causing this process. In any case, care must be taken with this type of diagnosis, since exposing the animal to acaricides free of charge is not very reasonable. Finally, there are serological tests on the market that detect the presence of antigens against this scabies and therefore tell us whether or not it is in the patient. In any case, if you notice that your dog does not stop scratching and that this is causing it to self-harm, take it to the vet . In the consultation they will make the diagnosis, and once the cause is detected, the treatment is very simple and effective. Imagine that this mite is like a microscopic spider that is dedicated to digging tunnels through the skin, it is evident how annoying and itchy it can cause, your dog will thank you for taking it to the vet. Finally, we answer the question we asked at the beginning and in the previous article:

Can dog mange affect my family?

The demodectic mange that we talked about in the previous article is NOT contagious to people , unlike scabies or sarcoptic mange, which CAN be spread from dogs to humans ; however, the consequences are minimal. The mite can pass through contact from the dog to the person, once in the person it can begin its action by digging the microtunnels, but the process is self-limiting since it will not be able to reproduce on our skin, so in the end it ends up dying and disappearing . Of course, while it is on our skin, it can cause itching and characteristic lesions. In any case, it is treated with the same active ingredient as in dogs and it is easy to eliminate. In any case, it is better to prevent and take care and extreme hygiene, and use antiparasitics with acaricide effect , to avoid the infection of these mites in our dog and in ourselves.
