Sarcoptes scabiei: Scabies-causing parasite (microscope image)

Which is

Scabies, also known as scabies, is a skin infection produced by a parasite that digs tunnels under the most superficial layers of the skin, causing irritation with its waste. These mites are transmitted through contact with infected people.


The most frequent scabies transmitter is the female of the parasite Sarcoptes scabiei, a white and black rounded arachnid less than 0.05 cm in size.

The mite penetrates the thinner regions of the skin, such as the interdigital and genital membranes, but can spread throughout the body.

This arachnid lives for about six weeks and lays its eggs in the skin tunnels. Every three weeks a new generation is born.

Itching Caused

The intense itching that characterizes this disease begins one month after the initial infection and can lead to secondary bacterial infections.


Treatment is based on the use of topical lotions prescribed by the doctor. After the cure of this infection, the patient becomes more sensitive, having a faster reaction to a new occurrence. It is important to treat all members of the same family to avoid a new infection.
