Which parasite is known to cause scabies?

1. Fleas

2. Ticks

3. Itch mite

4. Lice

The correct answer is: Itch mite

The itch mite, also known scientifically as Sarcoptes scabiei, is the parasite responsible for causing scabies. This microscopic mite burrows into the upper layer of the skin, leading to intense itching and discomfort. The condition is highly contagious and can spread through close physical contact, making it a significant concern in settings where individuals are in close quarters. While fleas, ticks, and lice are all parasitic organisms, they are associated with different conditions and symptoms. Fleas primarily cause flea bites and can lead to allergic reactions or flea infestations, while ticks are known for transmitting diseases like Lyme disease through their bites. Lice, on the other hand, are most commonly associated with head lice or body lice infestations, which result in itching but are distinct from the burrowing behavior of the itch mite that characterizes scabies. Understanding the specific characteristics and behaviors of these parasites helps in accurately diagnosing and treating infections.
