What Is Ringworm?

Ringworm, or tinea, is a fungal infection of the skin, caused by dermatophytes, a type of fungi that thrives on keratin, a protein found in skin, hair, and nails. These fungi lead to various conditions named after the body part they affect, such as tinea pedis (athlete's foot), tinea capitis (scalp), tinea corporis (body), and tinea cruris (jock itch).

How Does Ringworm Spread?

Ringworm spreads through direct contact with infected people, animals, or objects. The fungus can also be contracted from soil. Sharing personal items like towels, clothing, or sports equipment can facilitate its transmission. Pets, particularly cats, are common carriers of the fungus.

Who Is at Risk?

Children, athletes, and pet owners are particularly susceptible to ringworm. The communal use of facilities and close physical contact in sports, schools, and homes provide ideal conditions for the spread of ringworm.

Symptoms and Diagnosis

Common Symptoms of Ringworm

Symptoms include a red, itchy, circular rash with clear skin in the middle, resembling a ring. On the scalp, it can cause bald patches, while on the foot, it leads to scaling and cracking of the skin. Nails infected by ringworm become discolored, thick, and may crumble.

How Is Ringworm Diagnosed?

Diagnosis typically involves a physical examination. A healthcare provider may use a Wood's lamp to examine the skin or collect a small skin sample for a KOH exam or culture test to detect the presence of fungi.

Treatment Options

Over-the-Counter Treatments

Common OTC antifungal creams, such as clotrimazole and miconazole, are effective for mild to moderate infections. These creams are applied directly to the affected areas as per the instructions on the packaging.

Prescription Medications

Severe cases of ringworm may require prescription-strength antifungals, either topical or oral. Oral antifungals like terbinafine or itraconazole are used for scalp ringworm or severe body infections. These medications can have side effects and should be taken under medical supervision.

Home Remedies and Natural Treatments

Some popular home remedies include tea tree oil, apple cider vinegar, and coconut oil, known for their antifungal properties. While these can provide symptom relief, their efficacy varies, and they should not replace medical treatments for persistent or severe infections.

Personal Hygiene

Maintain good personal hygiene by showering regularly and keeping your skin dry, especially in folds and between toes. Use separate towels for the body and hair, and don’t share personal items like clothing, hairbrushes, or sports gear. Antibacterial body wipes are another good product for those looking to avoid ringworm and enhance their personal hygiene. 

Environment Cleanliness

Frequently clean and disinfect your home, especially surfaces that come into contact with bare skin, like furniture and bedding. Use antifungal sprays or bleach solutions in areas prone to moisture, such as bathrooms and kitchens, to kill any lingering fungi.

Complications and Misconceptions

Potential Complications of Ringworm

If ringworm is left untreated, it can lead to more severe bacterial infections, especially in cases of excessive scratching that leads to broken skin. Signs that warrant a doctor's visit include worsening symptoms, spreading of the rash, or if the infection affects the scalp or nails.

Common Myths About Ringworm

  • Myth: Only dirty people get ringworm.
  • Truth: Ringworm can affect anyone, regardless of personal cleanliness, since it spreads through contact with fungi.
  • Myth: Ringworm is caused by a worm.
  • Truth: It is a fungal infection and has nothing to do with actual worms

ALL Frequently Asked Questions About Ringworm 

When Is Ringworm Not Contagious?

Ringworm remains contagious as long as the fungi are alive on the skin and, without treatment, can continue to be spread. It becomes significantly less contagious about 24-48 hours after starting antifungal treatment and once the infected areas start to show signs of improvement. Complete healing is necessary to ensure it's not contagious, as fragments of the fungus can still cause infection until fully eradicated.

How Ringworm Spreads

Ringworm spreads through direct contact with an infected person or animal. It can also spread by touching objects or surfaces that an infected person or animal has touched, such as towels, bedding, clothes, and grooming items. Additionally, contact with fungi in the soil can lead to ringworm. Activities that involve close skin contact or shared facilities (like sports) can increase the risk of transmission.

Can Ringworm Kill You?

Ringworm itself is not a life-threatening infection and is generally considered a minor medical condition. However, if left untreated, it can lead to secondary bacterial infections, especially in people with weakened immune systems or other underlying health conditions. These secondary infections can potentially lead to more severe health issues, but with proper treatment, such outcomes are rare.

Will Ringworm Go Away on Its Own?

Some mild cases of ringworm may resolve on their own without treatment, but this can take a long time, during which the infection can spread to other parts of the body or to other people. Treatment with antifungal medications is recommended to speed up recovery, reduce symptoms, and prevent the spread of the infection.

Can Ringworm Spread?

Yes, ringworm can spread across different parts of the body from the initial infection site through contact. For example, touching a ringworm rash on the leg and then touching another part of the body can transport the fungus, leading to new infections. It’s important to avoid scratching the affected areas and to wash hands frequently to prevent spreading the infection to other body parts or to other individuals.

Can Ringworm Cause Fever?

Ringworm itself usually does not cause a fever. If a fever is present, it might indicate a secondary bacterial infection, especially if the ringworm-affected area becomes severely inflamed, overly painful, or if there are signs of a more significant skin infection. In such cases, it's crucial to seek medical advice.

Can Ringworm Not Itch?

Yes, it's possible for ringworm to not itch. While itching is a common symptom associated with ringworm, the severity of itching can vary widely among individuals. Some people may experience severe itching, while others may have a ringworm infection with little to no discomfort. The presence of symptoms can depend on the location of the infection and the individual’s immune response.

Can Ringworm Come Back?

Ringworm can recur, especially if the underlying conditions that favored the initial infection remain unchanged. Recurrence can happen if the treatment was not completed, if there's re-exposure to the fungus from infected individuals, pets, contaminated objects, or environments. Ensuring thorough treatment, maintaining good hygiene, and taking preventive measures are key to minimizing the risk of recurrence.

Will Ringworm Scar?

Ringworm usually does not leave scars after treatment. However, severe cases, particularly those that are not treated promptly or properly, can cause inflammation and damage to the skin that might lead to temporary discoloration or scarring. Avoiding scratching the infected area can also help prevent any potential scarring.

Can Ringworm Make You Sick?

Ringworm itself primarily affects the skin, hair, and nails and doesn't usually lead to systemic illness in otherwise healthy individuals. However, people with weakened immune systems may experience more extensive symptoms or complications. Generally, ringworm is not known to cause sickness or systemic symptoms like fever, body aches, or nausea in the way bacterial infections or viruses might.

How Long Does Ringworm Last?

The duration of a ringworm infection can vary depending on the site of infection and whether or not it is being treated. Without treatment, ringworm can last for several months, as the fungi thrive on the skin, nails, or scalp. With proper antifungal treatment, symptoms usually improve within 2 to 4 weeks. However, it's important to complete the full course of treatment as prescribed to ensure the fungus is entirely eradicated, preventing recurrence. It's also worth noting that nails and scalp infections typically take longer to clear up than those on the skin.

Which Fungus Causes Ringworm?

Ringworm is caused by a group of fungi known as dermatophytes. These fungi feed on keratin, a protein found in the skin, hair, and nails, leading to the various forms of ringworm. The specific types of dermatophytes that commonly cause ringworm include Trichophyton, Microsporum, and Epidermophyton. Each type tends to be associated with infections in specific body areas, for example, Trichophyton rubrum is a frequent cause of athlete's foot (tinea pedis) and jock itch (tinea cruris), while Microsporum canis is often responsible for ringworm of the scalp (tinea capitis), particularly in children.

Will Ringworm Cause Hair Loss?

Ringworm can cause temporary hair loss when it affects the scalp (tinea capitis). The fungus invades the hair shafts, leading to brittle hair that breaks off easily, creating bald patches. The hair loss is generally not permanent, and the hair typically regrows after effective treatment of the fungal infection. It's crucial to treat scalp ringworm promptly to minimize hair loss and prevent the spread of the infection.

Can Ringworm Come and Go?

Ringworm symptoms might appear to come and go, especially if the condition is not treated consistently or effectively. Environmental factors, personal hygiene, and the body's immune response can also influence the visibility and severity of symptoms over time. However, without proper treatment, the infection does not truly go away and can continue to spread to other parts of the body or to other people. Recurrences can happen if the initial infection was not fully eradicated or if there is re-exposure to the fungus.

Can Ringworm Cause Diarrhea?

Ringworm, being a fungal infection of the skin, scalp, or nails, does not cause diarrhea. Diarrhea is typically related to viral, bacterial, or parasitic infections that affect the gastrointestinal system, not fungal infections like ringworm. If someone with ringworm experiences diarrhea, it is likely coincidental or due to another underlying condition, and not a direct result of the ringworm infection.

Will Ringworm Itch When Healing?

Yes, ringworm can still itch while it is healing. As the skin recovers and the fungal infection subsides, the affected area may become dry and flaky, which can cause itching. It's important to continue treatment as prescribed and resist the urge to scratch, as scratching can lead to further irritation or infection. Moisturizing the area (with a product recommended by a healthcare provider) can help soothe the skin. However, if itching persists or worsens, it's advisable to consult a healthcare professional to ensure the treatment is effective and to rule out any complications.

Will Ringworm Go Away?

With proper treatment, ringworm typically goes away. Over-the-counter (OTC) antifungal creams, lotions, or shampoos are effective for most cases of ringworm on the skin. More severe cases, or infections of the scalp and nails, may require prescription-strength oral antifungal medications. It's crucial to follow the treatment plan as directed by a healthcare provider and complete the full course of medication, even if symptoms improve before the medication is finished, to ensure the fungus is completely eradicated and to prevent recurrence.

How Ringworm Starts

Ringworm starts when dermatophyte fungi come into contact with and colonize the skin, scalp, or nails. The infection begins to develop when the fungi find a hospitable environment to grow, such as warm, moist areas of the skin. Factors that can increase the risk of developing ringworm include direct contact with an infected person or animal, sharing personal items like towels or clothing with someone who has ringworm, and damp environments that facilitate fungal growth. The initial sign of ringworm is often a red, itchy, circular rash with clearer skin in the center, giving it a ring-like appearance.

Are Ringworm Itchy?

Yes, ringworm infections are often itchy. The degree of itchiness can vary depending on the individual and the area of the body that is infected. The itchiness is caused by the body's immune response to the fungal infection. Scratching the affected area can provide temporary relief but is generally not recommended as it can spread the infection to other parts of the body and lead to further skin irritation or a secondary bacterial infection.

Can Ringworm Live on Surfaces?

Yes, ringworm can live on surfaces for an extended period. The fungi that cause ringworm can be deposited on surfaces like floors, clothing, towels, bedding, and combs through contact with an infected person or animal. These fungi can survive on these objects, especially in warm, moist environments, making it possible for others who touch these surfaces to contract the infection. Regular cleaning and disinfecting of shared surfaces and personal items can help prevent the spread of ringworm.

Where Is Ringworm Most Common?

Ringworm can occur on any part of the body, but it is most commonly found on the scalp (tinea capitis), feet (tinea pedis, also known as athlete's foot), groin area (tinea cruris, also known as jock itch), and the skin (tinea corporis). The likelihood of developing ringworm in these areas is influenced by factors such as personal hygiene, environmental conditions, lifestyle activities (e.g., sports that involve close contact), and contact with infected individuals or animals. Warm, moist environments particularly favor the growth of the fungi responsible for ringworm, making places like locker rooms and public showers common areas for its spread.

Can Ringworm Cause Hives?

Ringworm itself does not cause hives, which are typically an allergic reaction manifesting as swollen, red welts on the skin. However, some individuals may experience an allergic reaction to the fungus that causes ringworm, leading to skin irritation or a rash that could be mistakenly thought of as hives. Additionally, the skin's reaction to ringworm can vary greatly among individuals, and symptoms like redness, itching, and discomfort are common. If hives develop in conjunction with a ringworm infection, it could be due to an allergic response to either the fungal infection or the medication used to treat it.

Are Ringworm Bald Spots Permanent?

Bald spots caused by ringworm on the scalp are usually not permanent. Once the infection is effectively treated, hair typically begins to regrow in the affected areas. However, if the infection is severe or left untreated for a long time, it can cause scarring on the scalp that might inhibit hair regrowth. Prompt and effective treatment is crucial to prevent such complications and to encourage healthy hair regrowth.

Can Ringworm Be Cured?

Yes, ringworm can be cured with appropriate antifungal treatment. The treatment plan may include over-the-counter antifungal creams, lotions, or shampoos for less severe infections or prescription antifungal medications for more serious or widespread infections. It's important to follow the healthcare provider's instructions and complete the entire course of treatment to fully eradicate the fungus and prevent the infection from returning.

Can Ringworm Live on Clothes?

Yes, the fungi that cause ringworm can live on clothes, as well as towels, bedding, and other fabrics. These organisms can survive for some time on these materials, especially if they are damp or soiled, which can facilitate the spread of the infection to others or reinfection of the same individual. Washing clothes, towels, and bedding in hot water and drying them in a hot dryer can help kill the fungi and prevent the spread of ringworm. It's also advisable to avoid sharing personal items to reduce the risk of transmission.

Are Ringworm and Jock Itch the Same?

Ringworm and jock itch are caused by the same type of fungi (dermatophytes), but the term "jock itch" specifically refers to a fungal infection in the groin area, known medically as tinea cruris. Ringworm, or tinea, can appear on various parts of the body, including the scalp (tinea capitis), feet (tinea pedis, or athlete's foot), nails (tinea unguium), and other skin areas (tinea corporis). Jock itch is a form of ringworm characterized by an itchy, red, often ring-shaped rash in the groin area. Although caused by the same fungi, the treatment and care for infections in different body parts can vary.

Where Does Ringworm Fungus Come From?

Ringworm fungus comes from a group of fungi known as dermatophytes that live on the dead outer layer of skin, hair, and nails. These fungi are widespread in the environment and can be found in soil, on animals, and on humans. People and animals can carry dermatophytes without showing any symptoms, acting as carriers and spreading the fungi to others. Environmental factors, such as humidity and warmth, can facilitate the growth and spread of these fungi.

Why Does Ringworm Keep Coming Back?

Ringworm can recur for several reasons, including incomplete treatment of the initial infection, reinfection from a contaminated environment or infected individuals or pets, and personal factors that make someone more susceptible to fungal infections (e.g., weakened immune system, excessive sweating). Preventative measures, such as maintaining good personal hygiene, treating infected pets, cleaning and disinfecting living spaces, and avoiding sharing personal items, are crucial to prevent recurrence.

Where Can Ringworm Be Found?

Ringworm can be found almost anywhere as the fungi responsible for it thrive in warm, moist environments. Common places include locker rooms, pool areas, gyms, and shower facilities where people walk barefoot and share surfaces. It's also found in homes, schools, and daycare centers. Additionally, the fungi can live on the skin and fur of animals, making pets common sources of ringworm infections in humans.

Where Does Ringworm Live?

Ringworm fungi live in the top layer of the skin, as well as in hair and nails, feeding on the keratin found in these tissues. These fungi can also survive outside the human body on surfaces and objects, such as clothing, towels, bedding, combs, and brushes, especially in damp and warm conditions. In the environment, these fungi are present in soil, which can be a source of infection for both humans and animals.

Why Does Ringworm Occur in Private Parts?

Ringworm occurs in private parts, known as jock itch or tinea cruris, primarily due to the warm, moist environment that the area provides, which is ideal for the growth of dermatophyte fungi. Factors contributing to the occurrence of ringworm in these areas include sweating, wearing tight or wet clothing for extended periods, and direct or indirect contact with the fungi through infected surfaces or personal items. Good hygiene practices and keeping the area dry and clean can help prevent the development of ringworm in private parts.

Are Ringworm and Roundworm the Same Thing?

No, ringworm and roundworm are not the same thing. Ringworm is a fungal infection of the skin, hair, or nails caused by dermatophytes and is characterized by ring-shaped, red, itchy patches. Roundworms, on the other hand, are a type of parasitic worm (nematode) that can infect the intestines and other body parts of humans and animals. The confusion between the two arises from their names, but they are entirely different in terms of cause, treatment, and health impact.

Are Ringworm Spores Airborne?

Ringworm spores can become airborne, particularly in cases of scalp ringworm (tinea capitis) where infected skin flakes or hair can carry spores into the air, especially during combing, brushing, or vigorous activity. However, the primary mode of transmission is direct contact with infected individuals, animals, or contaminated objects and surfaces. Airborne transmission is less common and typically requires close proximity to an active infection source.

What Does Ringworm Look Like When It Starts?

When ringworm starts, it typically appears as a small, red, circular or oval spot that may be slightly raised. The edges of the spot are often more red and may look scaly, while the center might clear up, giving it a ring-like appearance. The affected area can be itchy and uncomfortable. Over time, the ring may expand outward if left untreated. Early recognition and treatment are key to preventing the spread of the infection.

How Long Can Ringworm Live on Surfaces?

Ringworm fungi can survive on surfaces for extended periods, ranging from several months up to 18 months or more, depending on environmental conditions such as humidity, temperature, and the type of surface. The resilience of these fungi highlights the importance of regularly cleaning and disinfecting potentially contaminated items and surfaces, especially in communal areas where the risk of transmission is higher.

How Many Types of Ringworm Are There?

There are several types of ringworm, each affecting different parts of the body and caused by various species of dermatophyte fungi. Major types include:
