Rodent mite dermatitis is a skin condition caused by the infestation of mites that primarily live on rodents. These mites can occasionally infest humans, causing a range of skin symptoms.
Causes[edit]
Rodent mite dermatitis is caused by mites from the family Laelapidae and Myobiidae. These mites are ectoparasites, meaning they live on the surface of their host. They primarily infest rodents such as rats and mice, but can also infest humans if their primary host is not available.
Symptoms[edit]
The primary symptom of rodent mite dermatitis is pruritus, or intense itching. This is caused by the mite's bites and the subsequent allergic reaction in the skin. Other symptoms can include redness, swelling, and a rash. In severe cases, the constant scratching can lead to skin infections.
Diagnosis[edit]
Diagnosis of rodent mite dermatitis is often based on the presence of symptoms and a history of exposure to rodents. A skin scraping may be taken to identify the presence of mites. However, because the mites are often not present on the human host, diagnosis can be challenging.
Treatment[edit]
Treatment for rodent mite dermatitis involves addressing the symptoms and eliminating the source of the mites. Topical creams and oral antihistamines can be used to relieve itching. In severe cases, oral steroids may be prescribed. To eliminate the mites, it is necessary to remove any infested rodents and thoroughly clean the area.
Prevention[edit]
Prevention of rodent mite dermatitis involves controlling rodent populations and avoiding contact with infested areas. This can be achieved through pest control measures and maintaining clean living and working environments.
