The Scabies is caused by a skin parasite, Sarcoptes scabiei, a mite invisible to the naked eye that digs tunnels under the human skin and to lay its eggs.

How is it transmitted?

Through prolonged contact with an infected person with the parasite-infested bedding, with contaminated clothing.

What are the symptoms?

Itching, especially at night, is the most typical symptom. The discomfort is so unbearable that you end up injuring yourself scratching excessively.
On the skin, we assist to various types of lesions, such as papules (small raised red patches), vesicles and linear injuries, corresponding to the tunnels. There may be crusting or skin infections resulting from scratching. The most commonly affected areas are: the spaces between the fingers and toes, wrists, elbows, armpits, regions below the breasts, the abdomen, the male genitals and buttocks.

How is it diagnosed?

The diagnosis is made looking for a tunnel on the skin and looking for the parasite under a microscope, after taking a sample of a lesion.

How is it treated?

By applying specific (pyrethroid or other chemical substances) products on the infected skin. The therapy should be carried out following the instructions of the doctor to avoid recurrences.
Itching persists even after several weeks the parasite has been eradicated.

How to avoid spreading the disease?

If you come in contact with a person suffering from scabies it is recommended to:
- Carry out preventive treatment recommended by your doctor, after bathing or showering.
- Replace your own linens, sheets, pillowcases and towels after each application.
- Wash clothes in a washing machine at a temperature higher than 60 ° C.
- Put in a waterproof bag everything that can not be washed at high temperatures (blankets, pillows, woolen garments), closed for at least 48 hours and then expose it to air. The mite can not survive long away from human skin.
