Hi, Thanks for writing to HCM. Scabies is caused by a mite called Sarcoptes scabiei . It is an intensely itchy dermatosis. It is highly contagious. It spreads from person to person spread occurs via direct contact with the skin. The success of treatment is only by correct application of topical preparations. Scabies patients can be re-infested by untreated contacts. Also treatment failures have been reported, particularly resistance for the use of medication called permethrin. After effective treatment, itching and skin lesions generally subside within six weeks. Itching and skin lesions can appear on and off if secondary infection with bacteria Staphylococcus aureus. Hence, kindly consult Dermatologist and get properly evaluated for effective management. Hope the information provided would be helpful. All the best.
