Scabies mites are tiny, eight-legged parasites that cause a skin condition known as scabies. They are so small that they cannot be seen with the naked eye. These mites burrow into the outer layer of the skin, leading to intense itching and a rash. Scabies is highly contagious and can spread through close physical contact or sharing personal items. The life cycle of scabies mites involves laying eggs in the skin, which hatch and continue the cycle. Treatment typically includes topical medications that kill the mites and their eggs. It is important to treat all close contacts to prevent re-infestation.
