WHAT IS SCABIES?DEFINITION AND OVERVIEWScabies is a highly transmissible skin infestation caused by the Sarcoptes scabies mite. These microscopic mites burrow into the upper layer of the skin, where they lay their eggs and cause an intense allergic reaction. Scabies spreads through close, prolonged skin-to-skin contact with an infested individual. HOW SCABIES SPREADSScabies spreads when the mites are transferred from one person to another through direct contact. It can also occur indirectly by sharing infested personal items such as clothing, bedding, or towels. Scabies mites can survive for a few days without a human host, increasing the chances of transmission. RISK FACTORSCertain factors increase the risk of contracting scabies, including:• Living in crowded or close-quartered environments such as nursing homes, dormitories, or prisons.• Engaging in prolonged skin contact with an infested person, such as during sexual activity or through close family contact.• Weakened immune system, as scabies can be more severe and persistent in individuals with compromised immunity. 2. RECOGNIZING THE SYMPTOMSITCHY SKIN RASHThe hallmark symptom of scabies is an intense itch, particularly at night. The itch is a result of the allergic reaction to the mites and their waste products. The rash typically appears as small red bumps, blisters, or burrows in the skin folds, such as between the fingers, on the wrists, elbows, armpits, buttocks, or genital area. COMMON SITES OF INFESTATIONScabies mites have specific preferences for certain areas of the body, including:• Between the fingers and toes• Wrists, elbows, and armpits• Nipples (in women)• Genital area (in men)• Buttocks and waistline• Soles of the feet OTHER SYMPTOMS AND COMPLICATIONSIn addition to the rash and itching, scabies can cause other symptoms and complications, such as:• Secondary bacterial infections due to scratching and skin breakdown.• Allergic reactions, leading to hives or eczema-like skin inflammation.• Pustules or crusted scabies (more severe forms) in individuals with weakened immune systems. 3. CAUSES AND TRANSMISSIONSARCOPTES SCABIEI MITESScabies is caused by the Sarcoptes scabiei mite, which is a tiny eight-legged parasite. Female mites burrow into the skin, where they lay their eggs and deposit feces. The eggs hatch into larvae, which mature into adult mites, perpetuating the infestation. HOW SCABIES SPREADSScabies spreads primarily through prolonged skin-to-skin contact with an infested individual. This includes activities like hugging, holding hands, or sexual contact. It can also spread indirectly through infested personal items, such as clothing, bedding, or towels. Infestation can occur even if the infested person does not show visible symptoms. RISK FACTORS FOR CONTRACTING SCABIESSeveral factors increase the likelihood of contracting scabies, including:• Living or spending time in crowded environments where close contact is common.• Sharing personal items or bedding with an infested person.• Having a weakened immune system, which can make it more difficult to fight off the infestation. 4. Diagnosis and AssessmentPhysical ExaminationDiagnosing scabies usually involves a thorough physical examination of the affected person’s skin. The doctor will look for characteristic signs such as the presence of burrows, rashes, or small bumps in the typical areas of infestation. In some cases, a magnifying glass or dermatoscope may be used to aid in identification. Skin Scraping and Microscopic ExaminationTo confirm the diagnosis, the doctor may perform a skin scraping. During this procedure, a small sample of the affected skin is gently scraped off and examined under a microscope. This allows for the detection of the mites, eggs, or fecal matter, confirming the presence of scabies. 5. Treatment OptionsTopical MedicationsThe primary treatment for scabies involves applying prescription topical medications directly to the skin. Commonly prescribed creams or lotions contain insecticides that kill the mites and their eggs. Permethrin and ivermectin are commonly used medications that effectively eliminate scabies infestations. Oral MedicationsIn severe cases of scabies or when topical treatments fail, oral medications may be prescribed. Oral ivermectin is an ant parasitic medication that can be highly effective in eradicating scabies. It works by interfering with the nervous system of the mites, leading to their paralysis and subsequent death. Environmental MeasuresTo prevent reindentation and ensure complete eradication, it is essential to take certain environmental measures. in which include all clothing washing, bedding, and towels in hot water and drying them on high heat. Vacuuming upholstered furniture and rugs can help remove any mites or eggs that may be present. 6. Preventive MeasuresPersonal HygieneMaintaining good personal hygiene is crucial in preventing the spread of scabies. Regularly washing hands with soap and water, especially after close contact with others, can minimize the risk of transmission. Avoid sharing all types of personal items such as clothing, towels, or bedding etc.
