Scabies is a contagious skin infection caused by mite Sarcoptes scabies. Scabies Mites are very tiny microscopic parasite that burrows under the skin of their human host, causing intense allergic itching.
The scabies infection in animals is caused by a different but related species of mites known as the Sarcoptic Mange. In the absent of animals like the dogs and cats, these Sarcoptic Mange mites will bite and suck on human blood. Crusted scabies mites also known as the Norwegian scabies. Those with a weaker immune system are fertile breeding ground for the crusted scabies mites. Sufferers of crusted scabies mites exhibit scaly rashes and thick crusts of skin that contain thousands of mites making it harder to eradicates them.
Scabies Mites depend on humans and animals blood for food and for their breeding process. Scabies Mites are transmitted by direct skin to skin contact, infected clothing, beddings and seats. These mites can spread quickly in family, child care centers, schools, hotels and nursing homes. If someone in a family has scabies mites infection, it is advisable to treat the entire family or contact group to eliminate the mites.
Initial Scabies Mites infections require some 4 to 6 weeks to become symptomatic. However
reinfection of these mites may manifest symptoms within 24 hours. Signs and symptoms of Scabies mites include itching which is often severe and it get worse at night. These mites burrows into skin with thin, irregular burrow tracks which is made up of tiny blisters and bumps on the skin.
The burrows or tracks of Scabies Mites appears in folds of the skin. They are found between fingers, in armpits, around the waist, around breasts, along the insides of wrists, on inner elbows, soles of feet, around genital areas, on buttock, knees and around shoulder blade areas. Scabies mites can also be found on scalp, face and neck.
The female scabies mites feed on blood of the host, lay and deposit their eggs in the burrows. The eggs hatch into larvae in about two to three days and make their way to the surface of the skin. This movement will cause the host irritation and scratching. Scabies mites will thereby be picked up under the fingernails and hence the infection is spread to other areas of the host or passed on to their contacts by hand shakes and physical body contact. Scabies mites can also be spread through contact with other objects such as clothing, bedding, furniture, car seats and safety belts of vehicles.
