Which of the following diseases is caused by the human itch mite?
Scabies
Understanding Diseases Caused by Human Itch Mites
The question asks to identify the disease caused by the human itch mite. Let's examine the given options to determine the correct association.
Analyzing the Options
- Measles: Measles is a highly contagious viral illness. It is caused by the measles virus, not a mite.
- Scabies: Scabies is an intensely itchy skin condition caused by a tiny burrowing mite called Sarcoptes scabiei, also known as the human itch mite. The mite burrows into the upper layer of the skin where it lays eggs. This causes a rash and intense itching.
- Herpes: Herpes is a viral infection caused by the herpes simplex virus (HSV). It is not caused by a mite.
- Rubella: Rubella, also known as German measles, is a viral infection caused by the rubella virus. It is not caused by a mite.
Identifying the Disease by Human Itch Mite
Based on the analysis of the options, Scabies is the disease directly caused by the human itch mite, Sarcoptes scabiei. The other options (Measles, Herpes, and Rubella) are all viral diseases and are not associated with mites or other parasites as their primary cause.
Therefore, the disease caused by the human itch mite is Scabies.
| Disease | Causative Agent | Type |
|---|---|---|
| Measles | Measles virus | Virus |
| Scabies | Sarcoptes scabiei (Human Itch Mite) | Mite (Parasite) |
| Herpes | Herpes simplex virus (HSV) | Virus |
| Rubella | Rubella virus | Virus |
Conclusion on Human Itch Mite Disease
The human itch mite, Sarcoptes scabiei, is responsible for causing the skin condition known as Scabies. The life cycle of the mite within the skin leads to the characteristic symptoms of severe itching, especially at night, and a pimple-like rash.

Additional Information on Scabies and Mites
Scabies is contagious and can spread through prolonged direct skin-to-skin contact. It is a global health issue and can affect people of all races, ages, and income levels. Treatment typically involves prescription creams or lotions that kill the mites and their eggs. It's important to treat all people who have had close contact with the infected person to prevent re-infestation.
The human itch mite is very small, typically less than 0.5 mm in length, making it barely visible to the naked eye. It burrows into the epidermis, the outermost layer of skin, creating tunnels.
