There are over 46,000 species of mites, but all of them do not bite. The species that bite include Northerm Fowl Mite, Tropical Rat Mite and Itch Mite/Scabies Mite. Chiggers are the most common mite bites are reported from chiggers – insects too small to be seen with naked eyes and are usually groom during the late spring and summer in grass, weeds, wild berry, patches and woodland underbrush in damp. While, some mites can come in contact with human body from animals/pets, a few others are either transmitted from one human to other or from unhygienic spaces.
Is Scabies Mite Bite Dangerous?
Scabies mite (Sarcoptes Scabiei) is one of the most dangerous mites that can lead to sever itching and appearance of red, raised pimple-like spots on human skin. The symptoms last for couple of weeks after scabies is completely cured. Also, scabies infestation require proper medical treatment course which must be administered strictly in accordance with guidelines given by doctors.
Who is vulnerable to scabies mite bite?
S. scabiei mite either come in contact with human skin either from pets and domestic animals or they found in highly crowded, unhygienic living spaces in third world nations. Also, people in community shelters, nursing homes and similar institutions have greater chances of falling victim to scabies mite.
Why S.scabiei bite is dangerous?
S.scabiei infestation is common in a number of mammals including dogs, canids, horses, cattle, cats etc. Female mite tunnels into the epidermis (uppermost layer of skin) and lays eggs beneath it, which produce an intensely pruitic dermatitis with hyperkeatosis and alopecia. When hatched, eggs produce six-legged larvae.
Symptoms of Scabies
As allergic reaction to the entry of the mite inside human skin, infested body part develops highly pruitic lesions that often become causes of self mutilation due to excess scratching. Red, pimple like elevations appear on skin that either remains confined to a particular part or may spread to other parts of the body too. When put under hot water, itching in the infested part become intense. Another typical symptom of scabies is that itching increases during night as the mite is more active when temperature is above 20 degree Celsius.
Medical Treatment Course
Scabies is completely curable disease. Infested host/person must visit a doctor, who will prescribe a course of topical treatment – permethrin 5%. Patient is required to apply it twice a week so that under-skin mites and their eggs could be destroyed. There are other scabicides that a doctor could prescribe if permethrin fails to eradicate infestation.
Guidelines for Administration
Most important guidelines include applying of lotion with brush instead of cotton/wool. The lotion must reach the mite so that it could kill it. Normal pesticide-based lotions or those meant to cure similar skin conditions are not effective against scabies.
Scabies is highly contagious owing to mite’s ability to survive outside human skin for a couple of days. The mite can hide itself in bedding, cloths, or anything that comes in contact with the infested person. Therefore, a doctor will prescribe full scabies treatment course to all family members or any other who is sharing space with the infected person. Itching and red pimples could remain even after complete cure due to body’s allergic reaction to dead mite, its feces and dead eggs.
Scabies treatment failure must be considered only if symptoms continue to appear after month of last application of scabicide. The most common causes of scabies treatment failure are wrongly administered scabicides and poor adherence to guidelines. Often, first course of permethrin 5% succeed in killing the mite but fails to destroy eggs. When these eggs hatch, the symptoms of scabies re-appear and person is required to repeat the same medical treatment course.
