Scabies: symptoms, diagnosis, and effective treatment

Definition and symptoms of scabies

Scabies, or sarcoptosis, is a skin disease caused by the mite Sarcoptes scabiei. The parasite burrows into the skin, laying eggs and causing itching, especially at night. Symptoms include itching, rashes, and possible skin tracks or areas of inflammation. The diagnosis of scabies is usually made based on clinical symptoms and microscopic examination of skin secretions to detect the mite or its eggs.

Etiology of scabies

Scabies is caused by the mite Sarcoptes scabiei, which infects human skin. This parasite spreads through direct contact with an infected person or through contaminated household items. The mites tend to infect skin folds, the spaces between fingers, wrists, and other areas with soft skin, where they can successfully reproduce and cause symptoms of scabies.

  • Contact with an infected person: Transmission of Sarcoptes scabiei occurs through direct contact with an infected individual.
  • Contaminated items: Scabies mites can be transmitted through contaminated clothing, bed linens, or household items on which they can survive.
  • Sexual contact: Scabies can also be transmitted sexually as a result of close contact with an infected partner.
  • Migration of mites: Sarcoptes scabiei mites are capable of migrating across the skin, so they can cause infection in various areas of the body.
  • Low hygiene standards: Poor hygiene practices and improper use of shared items can contribute to the spread of scabies infection.

Clinical picture of scabies

The appearance of scabies symptoms usually begins a few weeks after infection with the Sarcoptes scabiei mite. Characteristic manifestations include intense itching and skin rashes, especially in areas where mites tend to infect, such as the hands, elbows, sides of the torso, and intimate areas. The exacerbation of symptoms at night is associated with the activity of the mites and an increase in skin inflammatory reactions.

Patients with scabies may also experience insomnia due to intense itching, leading to psychological discomfort and a deterioration in quality of life. It is important to pay attention to skin changes and symptoms in patients suspected of developing scabies for timely diagnosis and effective treatment.

  • Intense itching: Characterized by severe itching that worsens at night and can lead to skin lesions from constant scratching.
  • Rashes and skin redness: The skin develops small blisters, vesicular rashes, papules, and areas of redness at the infection sites.
  • Localization of the rash: Scabies rashes are typically found on the fingers, elbows, forearms, waists, buttocks, genitals, and other skin folds.
  • Insomnia: Intense itching that increases at night can lead to insomnia, resulting in psychological and physical strain.
  • Psychological discomfort: Constant itching and deterioration in the appearance of the skin can cause discomfort and lower self-esteem in patients.

Specialists’ view on the treatment of scabies

Expert opinion on the treatment of scabies emphasizes the need for a combined approach, including the use of antiparasitic agents and adherence to preventive measures to control the infection of those around. Worldwide specialists underline the importance of an accurate diagnosis and the prescription of effective therapy to prevent further spread of the infection.

The main focus is on the use of appropriate medications, such as permethrin or ivermectin, as well as the need to treat clothing, bedding, and household items. Preventive measures, such as regular washing, maintaining hygiene standards, isolating infected individuals and their contacts, are key aspects of successful control and treatment of scabies according to expert recommendations.

Methods of diagnosing scabies

Diagnosis of scabies typically includes a skin examination by a doctor and a demographic history considering clinical symptoms such as the characteristic itch and rashes. To confirm the diagnosis, additional studies are conducted, including microscopic examination of skin scraps, skin biopsy with microscopic investigation, or a tape test to detect mites or their eggs.

Laboratory tests may be used to confirm the diagnosis of scabies, such as a skin scraping to identify mites or a DPP test (dermatest with cover) that can show the skin’s reaction to scabies mite antigens. It is important to conduct an accurate diagnosis to prescribe effective treatment and prevent the spread of the infection.

  • Clinical examination: The doctor examines the skin, paying attention to the characteristic symptoms of scabies, such as rashes and itching.
  • Microscopic examination of skin crusts: This method allows for the detection of mites and their eggs on a sample of skin crust under a microscope.
  • Skin biopsy: If necessary, the doctor may take a sample of skin for biopsy and subsequent microscopic examination.
  • Sticky tape test: A sticky tape test may be used to identify mites or their eggs on the skin.
  • Laboratory tests: Include skin scraping to detect mites or a DPP test to assess the skin’s reaction to scabies mite antigens.

Methods of treating scabies

Treatment of scabies usually includes the use of topical medications containing pyrethroids or silver nitrate to eliminate scabies mites. Patients may also be prescribed antihistamines to reduce itching and skin reactions. After treatment, it is recommended to wash and disinfect clothing, bedding, and household items to prevent reinfestation.

In cases of complications or associated infections, a doctor may prescribe systemic medications such as antibiotics or corticosteroids. It is important to follow all of the doctor’s recommendations, adhere to the prescribed treatment, and carry out all necessary environmental disinfection procedures for a complete and successful cure for scabies.

  • Use of topical medications: Treatment of scabies often includes the use of ointments or creams containing anti-scabies agents such as permethrin or lindane. These medications help kill scabies mites on the skin.
  • Antihistamines: To relieve itching and reduce skin reactions, antihistamines are often prescribed, which help improve the patient’s comfort during treatment.
  • Disinfection of clothing and household items: An important component of scabies treatment is thorough washing and disinfection of clothing, bed linens, and other items to kill any potential mites and prevent reinfestation.
  • Systemic medications: In some cases, when scabies is complicated or accompanied by other infections, a doctor may prescribe systemic medications such as antibiotics or corticosteroids for more effective treatment.
  • Following doctor’s recommendations: It is important to follow all the doctor’s instructions, complete the full course of treatment, carry out all disinfection procedures in the environment, and avoid re-contact with potential sources of infection to prevent recurrences of scabies.

Measures for the prevention of scabies

Prevention of scabies includes adherence to hygienic measures, such as regular hand washing with soap, especially after contact with infected individuals or contaminated surfaces. Avoiding direct contact with infected patients and household items also plays an important role in preventing the transmission of the scabies mite. Since clothing and bedding can serve as refuges for the mites, their regular washing at high temperatures will also help reduce the risk of infection.

For scabies prevention, it is also important to monitor public places and ensure that sanitary standards are being observed. Infrequent use of shared items, such as clothing or hygiene products, can help avoid potential transmission of the infection. At the first signs of scabies, one should immediately consult a doctor for diagnosis and necessary treatment to quickly halt the spread of the disease.

  • Hygiene adherence: Regular and thorough hand washing with soap can help prevent the transmission of scabies mites.
  • Avoiding contact: It is important to avoid direct contact with infected individuals and their personal belongings to prevent infection.
  • Cleaning efforts: Regular washing of clothes, bed linens, and household items at high temperatures helps eliminate potential mites.
  • Compliance with sanitary standards: It is important to maintain cleanliness in public places and ensure adherence to sanitary norms to prevent the transmission of infection.
  • Minimizing contact with shared items: Avoid using shared items, such as clothing or personal hygiene products, to reduce the risk of infection.

Amazing Aspects of Scabies

Although scabies is often associated with extremely itchy skin rashes, an interesting fact is that the incubation period of the infection can be quite lengthy, reaching up to several weeks. This means that the symptoms of scabies may not appear immediately after contact with an infected mite, complicating diagnosis and control of the disease.

Another interesting aspect is the ability of the scabies mite Sarcoptes scabiei to survive on the skin and outside the human body for a certain period of time. This makes it difficult to eliminate infected household items, such as clothing or bedding, and highlights the importance of proper disinfection and isolation to prevent the spread of scabies.
