What Can Be Mistaken for Scabies?

Scabies is a common skin condition caused by tiny mites known as Sarcoptes scabiei. It is characterized by intense itching and a characteristic rash. However, scabies can sometimes be confused with other skin conditions that share similar symptoms. In this article, we will explore the various conditions that can be mistaken for scabies and discuss how to distinguish between them.

1. Introduction

Skin conditions can be perplexing, and scabies is no exception. While scabies has its distinct features, several other skin conditions can mimic its symptoms, leading to misdiagnosis and unnecessary treatments. It is crucial to understand these conditions to ensure accurate diagnosis and appropriate management.

2. Understanding Scabies

Before delving into the conditions mistaken for scabies, let’s briefly understand scabies itself.

Definition and Causes

Scabies is a contagious skin infestation caused by the Sarcoptes scabiei mite. These microscopic mites burrow into the top layer of the skin, where they lay eggs, leading to an allergic reaction and the characteristic symptoms of scabies.

Signs and Symptoms

The primary symptom of scabies is intense itching, especially at night. The itching is often accompanied by a rash consisting of small red bumps or blisters. Common sites of infestation include the hands, wrists, elbows, armpits, genitals, and buttocks. It is important to note that scabies can affect anyone, regardless of age, gender, or hygiene.

Common Misconceptions about Scabies

Before discussing conditions mistaken for scabies, let’s address a few misconceptions associated with this condition:

  1. Scabies is caused by poor hygiene: Scabies can affect anyone, regardless of their personal hygiene. It spreads through close skin-to-skin contact, not through lack of cleanliness.
  2. Scabies only affects certain populations: While scabies outbreaks can occur in crowded places such as nursing homes or prisons, it can affect individuals in any setting.
  3. Scabies is a sexually transmitted infection: Although scabies can be transmitted through sexual contact, it can also spread through non-sexual physical contact.

Now that we have a better understanding of scabies, let’s explore the conditions that can be mistaken for it.

3. Conditions Mistaken for Scabies

Contact Dermatitis

Contact dermatitis is a skin condition caused by exposure to irritants or allergens. It shares similarities with scabies, as both conditions can cause itching and a rash. However, contact dermatitis is typically localized to the area of skin that came into contact with the irritant or allergen.


Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, and inflamed skin. Like scabies, eczema can cause intense itching and a rash. However, there are a few key differences. Eczema rashes are often more widespread, covering larger areas of the body, and they can appear in flexural areas such as the inner elbows and behind the knees.


Pruritus, commonly referred to as generalized itching, is a symptom rather than a specific skin condition. It can occur due to various underlying causes, such as dry skin, allergies, or internal diseases. The itching in pruritus may resemble scabies, but the absence of a rash or visible burrows helps distinguish it from scabies.

Folliculitis is an infection or inflammation of the hair follicles, typically caused by bacteria or fungi. It manifests as small red bumps or pustules that may be itchy or painful. While the appearance of folliculitis can resemble scabies, the absence of the characteristic burrows helps differentiate between the two conditions.

Allergic Reactions

Allergic reactions to certain substances, such as medications, cosmetics, or insect bites, can produce symptoms similar to scabies. These reactions often cause itching, redness, and swelling in the affected areas. However, unlike scabies, allergic reactions usually occur in response to a specific trigger and are not contagious.

4. Distinguishing Scabies from Other Conditions

While the above conditions may share some similarities with scabies, it is essential to properly differentiate between them for accurate diagnosis and treatment. Here are some methods used to distinguish scabies from other conditions:

Physical Examination

A thorough physical examination by a healthcare professional is crucial in identifying the characteristics of the skin condition. They will inspect the rash, looking for specific features like burrows or patterns that are indicative of scabies.

Skin Scraping and Microscopy

In cases where scabies is suspected, a skin scraping may be performed. The healthcare provider will gently scrape the skin to collect a sample, which is then examined under a microscope. The presence of mites, eggs, or fecal matter confirms the diagnosis of scabies.

Other Diagnostic Tests

In some instances, additional tests may be conducted to rule out other conditions and confirm scabies. These tests may include skin biopsies or blood tests to detect specific antibodies associated with scabies infestations.

5. Treatment and Prevention

Once a diagnosis of scabies is confirmed, appropriate treatment can be initiated. It typically involves the use of medicated creams or lotions that kill the mites and alleviate the symptoms. In addition to medical treatment, certain home remedies and self-care measures can provide relief, such as keeping the skin clean and moisturized.

To prevent scabies and reduce the risk of misdiagnosis, it is essential to practice good hygiene, avoid close contact with infected individuals, and wash clothes and bedding in hot water. Regularly cleaning and vacuuming the living environment can also help eliminate mites.

6. Frequently Asked Questions (FAQs)

  1. Can scabies be transmitted through clothing or bedding? Scabies mites can survive for a short period away from the human body, so transmission through clothing or bedding is possible but relatively uncommon.
  2. Can pets transmit scabies to humans? Pets, such as dogs and cats, can get a different type of scabies mite that does not infest humans. However, they can cause a temporary skin reaction in some individuals.
