Scabies is best described as an itchy and highly communicable skin condition that is caused by the Sarcoptes scabei mite. These microscopic mites burrow into the surface of the skin where it thrives and lays eggs. The usual sites for infestation include the area in between the toes and fingers, around the knees, around the waist, around the shoulders, buttocks, neck, soles of the feet and palms of the hand.

The indicative symptoms of scabies include intense itchiness especially at night, irritation, rashes and sores due to scratching. The symptoms can take up to two months to manifest for those who are infested with scabies for the first time while an infected individual can still transmit the condition to others. Take note that scabies can be transmitted through direct skin contact, indirect transfer from clothing and sexual contact.
