Scabies, scientifically known as Sarcoptes scabiei, is a contagious skin infestation caused by microscopic mites. These tiny parasites burrow into the skin and cause intense itching and a characteristic skin rash. Scabies is primarily transmitted through prolonged skin-to-skin contact and can affect anyone, regardless of age or sex. To fully understand the nature of scabies, it is essential to break down the life cycle of these tiny pests.

Scabies Lifecycle:

  1. Infestation: Scabies infestation occurs when a fertilized female mite penetrates the outer layer of the skin, known as the epidermis.
  2. Burrowing: Once inside the skin, the female mite creates a network of tunnels, or burrows, in which she deposits her eggs.
  3. Egg development: The eggs hatch in 3 or 4 days, giving rise to larvae that then mature into nymphs.
  4. Mating: Adult male and female mites mate on the surface of the skin before the males die.
  5. New generation: Female mites continue to burrow deeper into the skin, feeding and laying more eggs, perpetuating the cycle.

The most common symptom of scabies is intense, incessant itching, which intensifies at night. This itching is the result of the body’s immune system reacting to the mite’s saliva, droppings, and eggs. The initial infestation may take several weeks to develop noticeable symptoms, especially in individuals who have not previously been exposed to scabies. It is important to recognize the characteristic signs of scabies to seek timely treatment and prevent the infestation from further spreading. Although scabies is highly contagious, it can be successfully treated with various antiparasitic medications prescribed by healthcare professionals.

Understanding Scabies: Causes, Symptoms, and Diagnosis

The main mode of transmission of scabies is direct skin-to-skin contact with an infected person. The mite can also be transmitted indirectly by sharing contaminated clothing, bedding, or furniture. The tiny mite penetrates the outer layer of the skin and lays its eggs, causing an allergic reaction and the formation of red, raised, itchy bumps known as a scabies rash.

Common Symptoms of Scabies:

  • Intense itching, especially at night
  • Rash with small grayish-white or skin-colored bumps
  • Burrows (thin, gray, thread-like lines) in the skin
  • Grai n-like irritations or sores

Note: It is important to keep in mind that the symptoms of scabies may take several weeks to appear in individuals who have never been infested before. However, in individuals who have previously had, the symptoms can develop in a few days. An adequate diagnosis and rapid treatment are essential to prevent the spread of scabies and relieve the inconvenience associated with this disease.

The diagnosis of scabies usually implies a physical examination carried out by a healthcare professional, which can look for characteristic signs such as burrows or eruptions. The healthcare professional can also collect skin samples or scrape the affected area to identify mite, eggs or microscope mite feces. In some cases, an increase lens known as dermatoscope can be used to help diagnosis.

Causes of Scabies

DIRECT CONTACT: The most common form of spreading scabies is direct and prolonged contact with an infected person. This can occur during activities such as hugs, sexual contact or by sharing bedding or bedding. Save mites can survive outside the human body for a brief period of time, so it is possible to contract infestation through contaminated objects.

Note: Save can also be transmitted by indirect contact, although it is less frequent. Indirect contact implies exposure to objects or surfaces with which an infected person has recently been in contact, such as furniture, towels or clothing. However, mites do not usually survive much time without a human guest.

  • Narrow living conditions: scabies is more frequent in overcrowded areas, such as nursing homes, prisons and nurseries. These environments are ideal for mites to spread from one person to another.
  • Bad personal hygiene: people who do not maintain good personal hygiene practices can be more susceptible to scabies infestation. The presence of dirt, sweat and fat in the skin can create a favorable environment for mites to thrive and multiply.
  1. Weakened immune system: People with a weakened immune system, such as those suffering from HIV/AIDS or undergo chemotherapy, run a greater risk of developing scabies. The weakened immune response makes the body more difficult to fight mites and their infestation.
  2. Personal habits: Certain personal habits, such as sharing bed or dressing with an infected person, can increase the probability of scabies transmission. In addition, narrow physical contact with infected people, for example in intimate relationships or sports activities, can also contribute to the spread of scabies.

To effectively prevent and control scabies, it is important to know the causes and risk factors associated with infestation. The spread of scabies can be minimized by applying adequate hygienic practices, avoiding direct contact with infected people or their belongings, and quickly looking for medical treatment.

Symptoms of Scabies

1. Picor: One of the main symptoms of scabies is intense itching, which can get worse at night. The itching is because mites are introduced into the skin and put eggs. It is important to note that it is possible that a person not experienced itching immediately after being infested with scabies, since the organism may take several weeks to develop an allergic reaction to mites. However, once the itching begins, it tends to persist and can become more intense over time.

“The itching caused by scabies is usually more intense at night.”

2. Cutaneous eruption: Another common symptom of scabies is the appearance of an eruption in the skin. The eruption usually appears in the form of small red protuberances or ampoules and can be accompanied by high gray white lines. These lines are the burrows that make the females of the mites when they move and put eggs under the skin. The eruption can appear in various parts of the body, such as hands, dolls, elbows, armpits, genitals and buttocks.

  • The eruption caused by scabies can be more pronounced in certain people, such as those who have a weakened immune system or older adults.
  • The appearance and severity of the eruption can vary from one person to another.

3. Secondary infections: In some cases, scabies can lead to secondary infections, especially if the affected person scratches the areas with itching excessively. Scratch can break the skin, creating an entry point for bacteria, which can lead to infections such as IMPETIGO or cellulite. These secondary infections can cause additional symptoms, such as redness, swelling and pain in the affected area.

  1. It is important to avoid scratching areas with itching to reduce the risk of secondary infections.
  2. Adequate hygienic practices, such as washing your hands regularly and keeping affected areas clean, can help prevent secondary infections.

In general, scabies can cause significant discomfort and distress due to its intense itching and characteristic rash. If you suspect that you or someone else may have scabies, it is crucial to seek medical attention for proper diagnosis and treatment to prevent the spread of the disease.

Diagnosing Scabies

1. Patient History: The first step in diagnosing scabies is to gather information about the patient’s medical history. The healthcare professional will ask about symptoms, their duration, and any recent contact with people who have been diagnosed with scabies. It is important that patients provide accurate and detailed information to aid in diagnosis.

Important information: Patients should mention if they have recently traveled to regions known for their high prevalence of scabies, as this may be a risk factor.

2. 2. Physical examination: A thorough physical examination is crucial to diagnose scabies. The healthcare professional will carefully inspect the patient’s skin, looking for characteristic signs of scabies infestation, such as burrows, a rash, and the presence of nodules or pustules. The skin folds and the areas between the fingers, toes and genitals are often affected.

3. Visual confirmation: In some cases, visual confirmation of the scabies mite or its eggs may be necessary to confirm the diagnosis. To aid in identification, a small scraping of skin can be taken from the affected area using a scalpel or blunt-edged blade. This sample is examined under a microscope. The presence of the mite, its eggs, or fecal pellets (scybala) can provide definitive evidence of the presence of scabies.

  1. Important note: The mite is usually not visible to the naked eye and requires magnification for accurate identification.
Characteristic signs Differentiating factors
Burrows Fine, slightly raised, wavy, grayish or skin-colored lines
Rash Severe itching, small red bumps or blisters
Commonly affected areas Skin folds, webs of fingers, toes, and genitals

How to Treat Scabies: Medications and Home Remedies

Medicines for scabies

  1. Topical creams and lotions: Prescription creams containing permethrin, benzyl benzoate, or sulfur are commonly used to kill mites and their eggs. These creams should be applied all over the body, from the neck down, and left on for a certain amount of time before rinsing them off thoroughly.
  2. Oral medications: In severe cases or when topical treatments are not effective, oral medications such as ivermectin may be prescribed. Ivermectin works by paralyzing and killing mites.

Home remedies for scabies:

  • Hot water treatment: immersing yourself in a bathtub full of hot water for at least 15 minutes can relieve itching and kill skin mites. Adding a cup of Neem oil, tea tree oil or downs to the bathtub can increase its effectiveness.
  • Washing and drying: All clothes, bedding and towels used by the affected person must be washed in hot water and dry over high heat to kill any mite or egg present. Ironing these garments can also help eliminate any remaining mite.
  • Cleaning of the environment: aspiring the house, especially upholstered furniture and carpets, and then discard the bag of the vacuum can help eliminate mites that may have detached from the skin. In addition, sealing the rarely frequent use items in plastic bags for a few days can hunger to mites.

It is important to consult a healthcare professional to obtain an accurate diagnosis and an appropriate treatment plan for scabies. Although home remedies can provide temporary relief, they may not completely eradicate infestation. In addition, all people who have had narrow and prolonged contact with the affected person must also be examined and treated to avoid reinfestation.

Medical Treatments for Scabies

1. Topical treatments:

Topical treatments are the main medical intervention against scabies. These medications apply directly to the skin and act on mites and their eggs. Among the most prescribed topical treatments are included:

  • Permetrin: This synthetic pyrethroid is the treatment of choice for scabies. It acts by paralyzing and killing mites and their eggs. Permetrine cream usually applies from the neck down and is allowed to act for a certain time before washed. It is usually well tolerated, even by young children and pregnant women.
  • Ivermectin: This oral medicine is another effective option to treat scabies. It acts interfering with the nervous system of mites, causing their paralysis and subsequent death. Ivermectin is usually prescribed in cases of severe or resistant scabies or when topical treatments cannot be used.

It is important to follow the prescribed treatment regime according to the indications of the healthcare professional to guarantee the complete eradication of mites and prevent reinstatement.

2. Environmental measures:

In addition to topical treatments, environmental measures are crucial to control scabies. These measures are intended to eliminate mites that may be present in the environment and avoid reinstatement. Some important environmental measures are:

  1. Washing and drying: All clothes, bedding and towels used by the infested individual must be washed in hot water and dry over high heat. This helps kill mites and their eggs.
  2. Aspirate: aspirate regularly and thoroughly clean the inhabited areas, furniture and vehicles can help eliminate mites that may have fallen from the infested individual.
  3. Isolation: Infused individuals should avoid close contact with other people up to at least 24 hours after starting treatment. This helps prevent transmission to other people.

It is essential to treat all nearby contacts and household members, even if they do not show symptoms, to avoid the propagation of scabies and a possible reinstatement.

  3. Cortese and limit your nails regularly to minimize the chances of mites hiding and spreading under their nails.

2. Avoid close and prolonged contact

Save is propagated through prolonged skin with skin, so narrow physical contact is an important risk factor. It is important to avoid sharing personal objects that are in close contact with other people to prevent the transmission of mites of scabies.

IMPORTANT: Avoid direct skin with skin with people who have a confirmed infestation of scabies, especially in busy places or during intimate encounters.

In addition, it is advisable to refrain from using the personal objects of an infected person, such as clothes, towels and bedding. Sharing these objects greatly increases the chances of contracting scabies.

3. Practice good environmental hygiene

Save mites can survive outside the human body for a brief period of time. Practicing good environmental hygiene helps limit the risk of infestation.

  • Regularly aspiring carpets, upholstery and mattresses, since scabies can live outside the human guest up to 72 hours.
  • Wash and dry infested clothes, bedding and other fabric items at high temperatures to kill any mite or egg.
  • Avoid narrow contact with infested furniture and clean and disinfect any potentially contaminated surface.

Following these preventive measures, people can minimize the risk of scabies and maintain good skin health. It is important to consult a healthcare professional in the face of any symptom or concern.

Scabies Prevention in High-Risk Environments

Personal hygiene and education: the promotion of good personal hygiene practices is key to preventing scabies in hig h-risk environments. Encourage people to wash their hands regularly with soap and water can help minimize the risk of transmission. In addition, an adequate education about scabies, their signs and symptoms, and preventive measures, to raise awareness and promote early detection, should be provided to all people of these environments.
