In this article, we will explore the early signs and symptoms of scabies so that you can identify it and seek proper treatment. So if you’ve noticed any strange rashes or intense itching lately, read on to learn more about what scabies start like and how to deal with it effectively.

Overview of Scabies Infection

Scabies is a contagious skin infection caused by the infestation of the human itch mite. It is a common skin condition that can affect people of all ages, genders, and socioeconomic backgrounds. Scabies is characterized by intense itching and a distinctive rash, which may lead to discomfort and distress if left untreated. This article aims to provide a comprehensive understanding of scabies, including its definition, causes, transmission, risk factors, symptoms, diagnosis, treatment options, prevention strategies, when to seek medical help, and managing scabies in specific settings.

Definition of Scabies

Scabies is a parasitic skin infection caused by the Sarcoptes scabiei mite, also known as the human itch mite. These microscopic mites burrow into the skin and lay eggs, resulting in a range of symptoms that can significantly impact an individual’s quality of life. Scabies is highly contagious and can easily spread through close physical contact with an infected person, or by sharing personal items such as clothing or bedding.

Causes of Scabies

The primary cause of scabies is the infestation of the human itch mite. This mite is typically transmitted through direct skin-to-skin contact with an infected individual. However, scabies can also be acquired indirectly through the sharing of contaminated personal items, such as clothing, towels, or bedding. It is important to note that scabies is not a reflection of poor hygiene; anyone can contract scabies, regardless of their cleanliness or living environment.

Transmission of Scabies

Scabies is most commonly transmitted through prolonged, skin-to-skin contact with an infected person. This includes activities like hugging, sexual contact, or sleeping in the same bed. The mites can also be spread indirectly when personal items, such as clothing or towels, are shared with an infested individual. It is important to take precautions to prevent the spread of scabies, especially in crowded or close-contact environments.

Risk Factors for Scabies

Certain factors may increase the risk of contracting scabies. These include living in crowded or close-contact environments, such as nursing homes, schools, or daycare centers. People with weakened immune systems, such as those living with HIV/AIDS or undergoing chemotherapy, are also more susceptible to scabies. Additionally, individuals who frequently engage in close physical contact, such as healthcare workers or individuals living in homeless shelters, may have an increased risk of acquiring scabies.

Initial Symptoms of Scabies

The early stages of scabies are often marked by specific symptoms that can help in its identification and diagnosis. The most common initial symptom of scabies is intense itching, particularly at night. This itching is often caused by the mites burrowing into the skin and laying eggs. Alongside itching, a red, bumpy rash may develop, with small raised bumps or blisters. Another characteristic sign of scabies is the presence of burrows, which are thin, wavy, thread-like lines on the skin where the mites have burrowed.

One of the primary symptoms of scabies is a persistent and intense itching sensation. The itching is usually worse at night and can be particularly bothersome, interfering with sleep and daily activities. Scratching the affected areas can provide temporary relief but may exacerbate the symptoms and potentially lead to secondary skin infections if the skin is broken.


A red, bumpy rash is a common symptom of scabies. This rash often appears as small raised bumps or blisters and can be found in various parts of the body, including the finger webs, wrists, elbows, waistline, and genital areas. The rash may be more widespread in infants, young children, or individuals with a weaker immune system.


One of the hallmark signs of scabies is the presence of burrows. These are small, thread-like lines on the skin, often found between the fingers, on the wrists, elbows, or any other warm and moist areas of the body. Burrows are created by the female mite as she tunnels under the skin to lay her eggs. These burrows may appear as thin, grayish, or silver-colored lines and are a significant diagnostic feature of scabies.

Commonly Affected Areas

Scabies can affect various parts of the body, and the distribution of the infection can vary depending on age and gender. In adults and older children, scabies often clusters in areas such as the wrists, elbows, armpits, waistline, buttocks, nipples, and genitalia. On the other hand, infants and young children may have scabies lesions on their scalp, face, neck, palms, and soles of the feet.

Difference Between Scabies and Other Skin Conditions

While scabies has characteristic symptoms, it can sometimes be confused with other skin conditions. Understanding the differences can help in proper diagnosis and appropriate treatment. Here are some common differentiating factors between scabies and other skin conditions:


Eczema is a chronic skin condition characterized by red, itchy, and inflamed patches of skin. It often appears in different areas of the body, such as the face, hands, behind the knees, and inside the elbows. Unlike scabies, eczema is not contagious and is commonly caused by a combination of genetic and environmental factors.

Contact Dermatitis

Contact dermatitis is an allergic reaction that occurs when the skin comes into direct contact with an irritant or allergen. It leads to redness, itching, and sometimes blisters or a rash. While contact dermatitis may be mistaken for scabies initially, it is not caused by mites and is not contagious.

Bed Bug Bites

Bed bug bites can often resemble scabies symptoms, with itchy red bumps or welts on the skin. However, bed bug bites are usually in a linear or clustered pattern and tend to occur on exposed areas during sleep. Unlike scabies, bed bug infestations have no burrows on the skin.


Hives, also known as urticaria, are itchy, raised, and red welts that appear suddenly on the skin. They can be triggered by allergens, medications, or infections. Hives are not contagious and typically disappear within a few hours or days.

Diagnosing Scabies

Diagnosing scabies usually requires a combination of clinical assessment, physical examination, and laboratory tests. While the signs and symptoms can be indicative, healthcare professionals often employ specific diagnostic methods to confirm the presence of scabies. These may include:

Physical Examination

During a physical examination, a healthcare provider will inspect the skin for characteristic signs of scabies, such as burrows, rash, or blisters. They may also ask about symptoms, medical history, and potential exposure to scabies.

Microscopic Examination

In some cases, a healthcare provider may perform a microscopic examination of skin scrapings taken from suspicious areas. By placing the skin scrapings under a microscope, the presence of mites, eggs, or fecal matter can be observed, providing definitive evidence of scabies infestation.

Burrow Ink Test

The burrow ink test involves applying ink or a topical medication to a suspected scabies burrow. After gently wiping away the excess ink or medication, the burrow lines remain visible, confirming the presence of scabies.

Skin Scraping

Skin scraping is another diagnostic technique where a healthcare provider gently scrapes the surface of the skin to collect samples for laboratory analysis. The samples are then examined under a microscope to identify the mites, eggs, or fecal matter.

Complications of Untreated Scabies

If left untreated, scabies can lead to various complications and secondary infections. Some possible complications of untreated scabies include:

Secondary Skin Infections

Constant scratching of the skin due to the intense itching can lead to breaks in the skin, creating openings for bacteria to enter and cause infections. Common secondary skin infections associated with scabies include impetigo and cellulitis.


Impetigo is a highly contagious bacterial skin infection characterized by red sores or blisters that ooze and form a yellowish-brown crust. It often occurs in areas where the skin is cracked or broken, such as around scabies lesions. Prompt treatment for scabies can help prevent the development of impetigo.


Cellulitis is a bacterial infection of the deeper layers of the skin. It typically causes redness, swelling, pain, and warmth in the affected area. If scabies leads to cellulitis, it can rapidly spread and potentially cause serious complications if not treated promptly.

Crusted Scabies

Crusted scabies, also known as Norwegian scabies, is a severe and highly contagious form of scabies. It is characterized by a thick, crusted rash that contains large numbers of mites, eggs, and fecal matter. Crusted scabies is more common in individuals with weakened immune systems, such as those with HIV/AIDS or undergoing immunosuppressive treatment.

Treatment Options for Scabies

Scabies is a treatable condition, and various treatment options are available to eradicate the mites and relieve the symptoms. The most common treatment measures for scabies include:

Topical Medications

Topical medications are commonly prescribed to treat scabies. These medications usually contain permethrin or lindane, which kill the mites and their eggs. The topical creams or lotions are applied to the entire body, from the neck down, and left on for a specific duration before being washed off. It is crucial to follow the instructions provided by healthcare professionals and complete the treatment regimen to ensure complete eradication of the mites.

Oral Medications

In more severe cases or when topical treatments are ineffective, oral medications may be prescribed. One commonly used oral medication is ivermectin, which effectively kills the mites. Oral medications are often administered in a single dose or as multiple doses spread over a few weeks, depending on the severity of the infestation.

Home Remedies

While prescription medications are the most effective treatment for scabies, certain home remedies may help relieve symptoms and serve as adjunctive measures. These include applying cool compresses to alleviate itching, taking oatmeal baths to soothe the skin, and practicing good hygiene to prevent reinfection.

Treatment for Close Contacts

It is crucial to treat all close contacts of an individual diagnosed with scabies, even if they do not present with symptoms. This prevents the spread of scabies and potential reinfection. Close contacts, such as family members, sexual partners, or roommates, may need to undergo the same treatment regimen as the affected individual.

Preventing Scabies

Taking preventive measures can help reduce the risk of scabies transmission and infestation. Some effective ways to prevent scabies include:

Maintaining Good Hygiene

Practicing good hygiene is essential in preventing scabies. Regularly washing your hands with soap and water, especially after coming into contact with an infested individual or their personal items, can minimize the risk of transmission. Additionally, keeping your skin clean, dry, and moisturized may aid in preventing scabies infection.

Avoiding prolonged, close physical contact with an infested individual is crucial in preventing scabies transmission. This includes refraining from sharing personal items such as clothing, bedding, towels, or brushes. If you suspect you have come into contact with scabies, it is essential to seek prompt medical attention for diagnosis and treatment.

Washing and Drying Clothes Properly

To eliminate scabies mites from clothing and bedding, it is important to wash them in hot water and dry them using high heat. This helps kill the mites and prevents reinfection. If washing facilities are not available, storing infested items in a sealed plastic bag for at least 72 hours can also help in mite elimination.

Cleaning and Vacuuming Living Spaces

Regularly cleaning and vacuuming the living spaces can help remove any mites that may be present. Pay particular attention to areas where skin contact is frequent, such as couches, chairs, and mattresses. Vacuuming the carpets and rugs can also minimize the risk of infestation or reinfestation.

When to Seek Medical Help

While scabies can often be treated effectively at home, several situations warrant seeking medical help. Some instances where medical assistance should be sought include:

Persistent Itching

If the itching persists or worsens despite home care measures and treatment, it is advisable to consult a healthcare professional. Persistent itching may indicate an incomplete response to treatment or the possibility of a secondary skin infection.

Worsening of Symptoms

If the symptoms worsen after initiating treatment, it is essential to seek medical help. This includes the development of new lesions, spreading of the rash to different areas, or the appearance of more intense itching.

Development of Crusted Scabies

The development of crusted scabies requires immediate medical attention. Crusted scabies can be highly contagious and may indicate a more severe infestation requiring aggressive treatment approaches.

Spreading of Infection

If other individuals in close contact with an infested person begin experiencing symptoms, it is important to seek medical help. Early diagnosis and treatment can prevent the further spread of scabies.

Managing Scabies in Specific Settings

Scabies infestations can pose unique challenges in specific settings, such as nursing homes, schools, daycare centers, and homeless shelters. Proper management and preventive measures are crucial to preventing outbreaks and reducing the risk of transmission. Here are some considerations for managing scabies in specific settings:
