Feer Disease, also known as Feer syndrome or trombiculiasis, is a rare and specific form of trombiculid mite infestation that affects humans and animals. The disease derives its name from the French entomologist, Jules Pierre Evariste Feer, who first identified and described the condition in the early 20th century.
Feer Disease is caused by the bites of the larvae of certain species of trombiculid mites, commonly referred to as chiggers or harvest mites. These minuscule mites are found in grassy and wooded areas, particularly during warm and humid seasons. When in contact with the skin, the larvae attach themselves and ingest the host's tissue fluids by piercing the dermis with their mouthparts, causing intense itching and discomfort.
The characteristic symptoms of Feer Disease include relentless itching, localized redness, and the formation of small red papules, which may resemble a rash or hives. The affected areas are typically found on skin regions in close contact with grass, such as ankles, thighs, and waist.
Although the symptoms of Feer Disease are not life-threatening, they can significantly affect the quality of life due to the persistent itchiness, discomfort, and potential complications from scratching, such as secondary bacterial infections.
Treatment usually involves managing the symptoms, such as alleviating itching with antihistamines, applying topical corticosteroids to reduce inflammation, and practicing good hygiene to prevent infections. Preventive measures, such as wearing protective clothing, applying insect repellents, and avoiding areas known for mite infestations, can reduce the risk of contracting Feer Disease.
