What are the dangers of mites to us? What are the dangers of mites

Mites are the most rampant human indoor pests after fleas and flies, and they rely on sucking people's tissue cells and glands to secrete oil. There are many kinds of mites, almost 500,000 species, which are hidden in the family and closely related to human health mainly dust mites, scabies mites, Demodex mites, powder mites, pamptail mites, fruit mites, sweet mites, etc., dark corners of the room, carpets, mattresses, pillows, sofas, air conditioners, etc., are places where mites breed. Experts say that mites can cause allergies, intestinal mites and lung mites, so regular removal of mites should be an important part of household cleaning.

Allergies: Dermatitis can occur when people come into contact with mites-contaminated objects. These mites can parasitize or bite almost all parts of the human body, especially children, and the most common parts are the tender and folded parts of the human body.

People with allergies can develop allergic asthma, allergic rhinitis, or atopic dermatitis when they are exposed to dust mites. The parts of the mites, their secretions, excretions, and the skin that has been shed are allergens. These substances fly in the air as beds are made, quilts are folded, and the floor is swept away.

When people inhale through breathing, they will have an uncomfortable reaction, which will seriously affect their life and work.

Mites can also enter the body's digestive tract or respiratory system through daily diet or breathing, causing intestinal mite disease and lung mite disease. The main symptoms of intestinal mite disease are diarrhea, vomiting, sometimes blood in the stool, and even intestinal ulcers. The mites that cause intestinal mite disease are mainly sweet fruit mites, carrot and some meal mites, which are mainly found in various foods, especially sweet foods, dried foods, sausages, medicinal herbs, grains and some other items that have been stored for a long time.

The symptoms of pulmonary mite disease are similar to those of diseases such as tuberculosis and bronchitis, with cough, sputum production, hemoptysis, wheezing, and chest tightness. In addition, mites can also cause urinary mite disease after entering the urethra and spinal mite disease after entering the spinal cord.

Acts as a vector: In addition to direct pathogenesis, it can also transmit various diseases such as qiangworm, epidemic haemorrhagic fever, murine spottings, typhoid, toxoplasmosis, rickettsial disease and rabies.

60% of people will have mites on their faces.

Our understanding of mites often starts with the face, because almost 60% of people will have mites on their faces. The pathophysiological process of acne is mainly manifested by abnormal keratinocyte keratinization in the hair follicle, and high levels of sebum secreted by patients with severe acne.

Due to hyperkeratinization of the sebaceous ductal epithelium, sebum drainage is not smooth, resulting in clinical comedones. The sebum trapped in the hair follicle can burst through the cyst wall and enter the surrounding tissues, triggering an inflammatory response that produces the initial inflammatory damage of acne. After acne formation, bacteria such as P. acnes overgrow, further aggravating the inflammatory damage of acne.

Therefore, the formation of ductal plugs in the sebaceous ducts of hair follicles and co-infection on this basis is the key to the pathogenesis of acne. In other words, almost 60% of people have a mite infection on their face, and 20% of them have acne, but this does not mean that acne is caused by mites.

Mites are too harmful, and it is not good to pay attention to.

The most common mite diseases are:Ear mites, scabies mites and Demodex mites。Ear mites are a kind of mites parasitic in the ear canal, which often cause local itching, ear shaking, and brown discharge in the ear canal visible to the naked eye. Scabies mites live in the epidermis and can cause severe itching, with surface flushing, rash-like nodules, thickening, and crusting, usually due to frequent scratching and hair loss.

Demodex mites usually live in sebaceous glands and hair follicles. Generally, it is more common on the face, limbs and armpits, and the affected part is red, scattered in the red rash, pustules can be formed after infection, and there is more body odor. The above cases can be controlled by a combination of internal and external**, but Demodex is difficult**.

After the patient is bitten by a mite, there will be an inflammatory reaction locally**, such as pimples accompanied by itching, and specific mites may cause blisters, eschars, etc. Some mites can also cause allergic diseases, such as eczema after exposure, nasal congestion, runny nose or asthma after inhalation. Some mites will parasitize in the human body, and after inhalation, the mites will parasitize in the bronchioles and lung parenchyma, and there will be pulmonary mite disease, respiratory symptoms such as cough and sputum production, and after eating, the mites will parasitize in the intestines, intestinal mite disease, abdominal pain, diarrhea and other digestive symptoms.

If an infant is exposed to dust mites, they will develop facial eczema, which appears as a red, edematous papule the size of a miliary grain, after which fluid may ooze and crust over. Adults often have eczema or become rough like lichen in delicate parts, such as the elbow fossa, axillary fossa and popliteal fossa.

If the patient is immunocompromised, has a severe systemic disease, severe diabetes, leukemia, or is on immunosuppressant drugs, after being attacked by scabies mites, Norway scabies may appear, which is manifested as eczema-like papules all over the body, and there may be extensive thick scabs, cracks, and hair may become dry.
