Demodecosis is a dermatological disease caused by subcutaneous demodex tick. The parasite lives in the sebaceous glands, hair follicles. It feeds on particles of the epidermis, fat, hormones. It activates its vital activity while weakening the immune system. It manifests itself in skin rashes, allergies, conjunctivitis. Whether or not demodicosis is contagious, transmission routes, consequences are further in the article.
Features of the mite
Demodex is a conditionally pathogenic microorganism. In 90% of the world's population, ticks are present on the skin. However, not everyone has signs of the disease. Most people are carriers. Under the influence of certain factors, microorganisms become more active and begin to multiply actively.
Is localized subcutaneous tick on the face, the head, since it is there that a large number of hair follicles, sebaceous ducts are concentrated. The parasite feeds on particles of the epidermis, fat. All the time active reproduction of microorganisms, a person does not feel anything. After 20 days, the tick dies, begins to decompose, poison the cells. At this point, symptoms of demodicosis appear.
Important!
The first manifestations, experts call the presence of rosacea - acne. There are inflammations, pustules, redness of the skin, the vascular network, and the pores expand. Itching, a feeling of tightness of the skin on the face are worried. With a long course of the disease, complex forms of demodicosis, infection spreads to the chest, back. The elderly are often diagnosed demodicosis of the eyes with purulent discharge in the corners.
How is a subcutaneous tick transmitted?
According to experts, demodicosis is transmitted to infants from the mother on the seventh day after birth. Symptoms do not always appear. That the disease is transmitted from person to person has been repeatedly proven. There are several ways of infection, but close contact with the source of the disease is always necessary.
Demodecosis in people is transmitted through hugs, kisses, contact with infectious things, bedding, hygiene products, through hats, combs, towels, napkins. Demodecosis in humans is contagious even in the absence of vivid symptoms of the disease, with carriage.
Interesting!
The erroneous opinion that it is possible to get infected with Demodex tick from animals. Pets often suffer from this disease, but are not a source of infection for humans. A tick when it gets on people's skin dies after a while, does not live for a long time, does not breed, because the conditions are not suitable. He needs a coat that a person does not have.
