Summary
During hot and humid weather, various skin conditions, including ringworm, tend to become more common. Ringworm, also known as dermatophytosis or tinea, is a fungal infection that affects the skin. Despite its name, ringworm is not caused by a worm but by fungi called dermatophytes.
When tinea fungi infect the skin, they create circular patches that are often itchy. The edges of these patches are typically red and raised, while the center may appear lighter in color and flaky due to scaling. The infection can present as a single patch or multiple patches that can spread to different areas of the body. Ringworm can affect almost any part of the body, including the scalp, face, neck, arms, hands, nails, groin, buttocks, thighs, legs, and feet.
Apart from its unsightly appearance, ringworm is highly contagious. The infection can spread through direct skin contact with an infected person or by touching items that have been contaminated, such as clothing, towels, combs, or bed linens. It can even be contracted by sitting on a chair or lying on a bed used by someone with ringworm.
Although ringworm is contagious, it is easily treatable with antifungal creams or ointments and maintaining proper hygiene, such as daily bathing. Some home remedies can also help speed up recovery and soothe the affected skin.

Symptoms of Ringworm
Identifying ringworm is relatively straightforward, as it presents with distinctive signs and symptoms. A person may have ringworm if they exhibit the following characteristics:
- Circular Patches on the Skin. Ringworm often appears as one or more circular patches on the body. These patches may vary in size and can develop in various locations, including the scalp, face, arms, legs, or other parts of the body.
- Scaly Appearance. The affected areas tend to be scaly, especially in the center of the patch. The skin in this area may look dry and flaky, which is a hallmark sign of the infection.
- Raised Edges. The edges of the ringworm patch are typically more raised and prominent than the central area. This creates a “ring-like” appearance, with the outer rim being slightly elevated.
- Redness Around the Edges. The border of the patch is usually red or reddish-brown, while the center may appear lighter in color. This difference in coloration between the edges and the center helps distinguish ringworm from other skin conditions.
- Itching. The patches are often accompanied by itching, which can range from mild to severe. The level of itchiness may vary depending on the severity of the infection and the sensitivity of the affected skin.
These symptoms can help confirm the presence of ringworm, making it easier to recognize and seek appropriate treatment. Prompt use of antifungal creams or ointments can help alleviate symptoms and prevent the infection from spreading to other areas of the body or to other individuals.
Types of Ringworms
Ringworm can occur in various forms, depending on the part of the body affected. Each type of ringworm has a specific name based on its location:
- Tinea Capitis. This type of ringworm affects the scalp and is commonly seen in children. It can cause scaly, itchy patches on the scalp, often leading to hair loss in the affected areas. Tinea capitis is often contracted in barbershops due to the use of contaminated tools.
- Tinea Barbae. Tinea barbae occurs in the beard area, including the facial hair and neck. It affects men more commonly and can cause redness, scaling, and sometimes pustules. If ringworm is present on the scalp, it may also spread to the beard area.
- Tinea Faciei. This form of ringworm appears on the face, excluding the beard area. It often presents as red, scaly patches that may worsen with sun exposure. Tinea faciei can develop from contact with contaminated items, such as towels or washcloths that harbor the fungus.
- Tinea Corporis. Tinea corporis affects the body, including the arms, chest, abdomen, back, or legs. The rash is typically ring-shaped with a raised, red border and a clearer center. Because the affected areas are usually not as sweaty, tinea corporis is easier to treat compared to other forms of ringworm.
- Tinea Manuum. This type of ringworm occurs on the hands, often between the fingers or on the palms. It can cause redness, scaling, and itching, sometimes making the skin appear dry and cracked.
- Tinea Pedis. Commonly known as athlete’s foot, tinea pedis affects the feet, especially between the toes. Symptoms include itching, scaling, and sometimes painful cracks in the skin. It is particularly common among individuals who frequently wear tight shoes or spend time in damp environments.
- Tinea Unguium (Onychomycosis). This type of ringworm affects the nails, leading to thickened, discolored, or brittle nails. The infection may appear as white or yellow patches on the nail and can affect either the fingernails or toenails.
- Tinea Cruris. Known as jock itch, tinea cruris affects the groin, buttocks, and inner thighs. It is more common in men and athletes due to sweat accumulation in these areas, which creates an environment where the fungus can thrive. Symptoms include red, itchy patches with a well-defined edge.
Each type of ringworm requires appropriate treatment, often with topical or oral antifungal medications. Early diagnosis and treatment can help prevent the infection from spreading to other body parts or to other people.
Diagnostic Procedures for Ringworm
Diagnosing ringworm involves evaluating the symptoms and using specific tests to confirm the presence of the fungal infection. Here are the common diagnostic procedures for ringworm:
- Physical Examination. The first step in diagnosing ringworm is a thorough physical examination of the affected area. A healthcare provider will look for the characteristic signs of ringworm, such as red, circular patches with raised, scaly edges and a clearer center. The doctor may also ask about recent activities, contact with animals, or exposure to people who may have ringworm to assess the likelihood of fungal infection.
- Wood’s Lamp Examination. A Wood’s lamp, which emits ultraviolet (UV) light, can be used to examine the skin in a darkened room. Certain types of fungi will fluoresce under the UV light, displaying a greenish or bluish glow. While not all types of ringworm show fluorescence, this test can help detect some strains and differentiate them from other skin conditions.
- Microscopic Examination (KOH Test). A potassium hydroxide (KOH) preparation test is a common diagnostic procedure for fungal infections. The doctor will gently scrape a small sample of the affected skin and place it on a microscope slide with a drop of KOH solution. The KOH dissolves the skin cells, making the fungal elements easier to see under a microscope. The presence of fungal hyphae (branching filaments) confirms ringworm.
- Fungal Culture. In some cases, a fungal culture may be performed to identify the specific type of fungus causing the infection. A sample of the skin, hair, or nail is collected and placed in a special medium that promotes fungal growth. Although this test can take several days to weeks to produce results, it is useful for identifying the exact fungal species, especially in persistent or recurring cases.
- Skin Biopsy. If the diagnosis remains uncertain or if the symptoms are atypical, a skin biopsy may be conducted. This involves taking a small sample of skin tissue from the affected area for laboratory analysis. The biopsy can help rule out other skin conditions that mimic ringworm, such as psoriasis or eczema.
- Nail Clipping Test. If ringworm affects the nails (tinea unguium or onychomycosis), a sample of the affected nail can be clipped and examined under a microscope or cultured to confirm the diagnosis.
These diagnostic procedures help confirm ringworm, allowing for the appropriate antifungal treatment to be administered. Early diagnosis and treatment are important to prevent the infection from spreading to other parts of the body or other individuals.
Complications of Untreated Ringworm
While ringworm is generally a manageable condition, leaving it untreated can lead to several complications that affect both the skin and overall health. These complications can be more severe in individuals with weakened immune systems or when the infection spreads to certain areas of the body. Here are some potential complications of untreated ringworm:
- Worsening of the Infection. If left untreated, ringworm can spread to other areas of the body, resulting in multiple patches of infection. This can cause increased discomfort, itching, and skin damage. The infection may also deepen, leading to more pronounced scaling, cracking, and blistering.
- Secondary Bacterial Infections. Persistent scratching due to intense itching can break the skin’s barrier, allowing bacteria to enter and cause secondary bacterial infections. Signs of a bacterial infection include increased redness, swelling, pain, or the presence of pus. This may require antibiotic treatment in addition to antifungal medications.
- Chronic Infection. Without proper treatment, ringworm can become a chronic or recurring condition. The infection may persist for months or even years, especially in areas prone to moisture, such as the feet (athlete’s foot) or groin (jock itch). Chronic ringworm may require long-term antifungal therapy to manage effectively.
- Spread to Nails (Onychomycosis). Ringworm can spread to the fingernails or toenails, leading to a condition known as onychomycosis. When the nails become infected, they may thicken, discolor, and become brittle, making the infection difficult to treat and often requiring oral antifungal medication.
- Permanent Hair Loss or Scarring (Tinea Capitis). If ringworm affects the scalp (tinea capitis) and is left untreated, it can lead to hair loss in the affected areas. In severe cases, the hair loss may be permanent due to scarring. This can be especially problematic in children and may affect self-esteem.
- Fungal Abscesses (Kerion). Untreated ringworm of the scalp can develop into a kerion, a severe inflammatory reaction characterized by swollen, pus-filled lesions. A kerion is painful and may result in permanent scarring and hair loss if not promptly treated.
- Systemic Fungal Infection. Although rare, untreated ringworm can lead to a systemic fungal infection, especially in individuals with weakened immune systems (e.g., people with HIV/AIDS, cancer, or diabetes). The infection can spread beyond the skin, potentially affecting internal organs and requiring more aggressive treatment.
- Transmission to Others. Ringworm is highly contagious and can easily spread to others through direct contact or shared items such as clothing, towels, or sports equipment. Untreated ringworm increases the risk of infecting family members, friends, or teammates.
Proper diagnosis and timely antifungal treatment can help prevent these complications. If ringworm symptoms persist despite using over-the-counter treatments, it is important to consult a healthcare professional for further evaluation and treatment.
Causes of Ringworm

Ringworm is a common skin infection in the Philippines, largely due to the country’s hot and humid climate, which creates ideal conditions for the growth of fungi. The primary cause of ringworm is a type of fungus called dermatophyte, which is also known as tinea. This fungus can be contracted through various means, including:
- Direct Contact with Infected Skin. Ringworm can spread easily through skin-to-skin contact with someone who has the infection. Even simple actions like shaking hands or touching an affected area can transfer the fungus to another person.
- Handling Infected Animals. Pets and other animals can also carry ringworm, and the infection can be passed to humans through direct contact. Because the fungus can be hidden beneath the fur, it may not always be obvious that an animal is infected, making transmission more likely.
- Using Contaminated Objects. Ringworm can be contracted by touching objects that have been used by an infected person. Items such as clothing, towels, combs, chairs, or bed linens can harbor the fungus and should not be shared. In public places like gyms, it’s important to use personal items and avoid sharing gear.
- Playing in Soil or Mud. Children are particularly at risk for ringworm due to outdoor activities. The tinea fungus can be present in soil, and contact with contaminated ground or mud can lead to infection, especially if the skin has small cuts or abrasions.
- Poor Hygiene Practices. The tinea fungus thrives in unclean areas of the body, especially in spots that sweat frequently, such as the feet, groin, and underarms. Inadequate hygiene can promote the growth and spread of the fungus, increasing the risk of ringworm.
Understanding these causes can help reduce the risk of contracting ringworm by encouraging good hygiene, avoiding direct contact with infected individuals or animals, and practicing caution when using shared items.
Prevention of Ringworm

To reduce the risk of contracting ringworm, follow these preventive measures:
- Maintain Proper Hygiene. Keeping the body clean is essential for preventing skin infections like ringworm. Make it a habit to bathe twice daily, especially in hot and humid climates. After bathing, dry the body thoroughly, paying extra attention to areas that sweat frequently, to prevent fungal growth.
- Regularly Bathe Pets. If you have pets such as cats or dogs, make sure to bathe them regularly to remove any fungi that may have attached to their fur. This helps reduce the risk of ringworm transmission from pets to humans.
- Wash Hands Frequently. Regular handwashing is a simple yet effective way to prevent not only ringworm but also various other infections. Wash your hands after petting animals, playing outside, or coming into contact with potentially contaminated surfaces.
- Avoid Sharing Personal Items. Do not share personal belongings such as clothing, towels, hairbrushes, or combs, as these items can harbor fungi. Using someone else’s personal items increases the risk of infection.
- Keep the Home Clean. Make it a habit to clean household items and frequently touched surfaces, especially after having guests. Visitors can unintentionally bring fungi into the home, so regular cleaning can help reduce the risk of contamination.
- Ensure Adequate Ventilation. To avoid excessive sweating, make sure the rooms in your home are well-ventilated by using an air conditioner or fan. If you’re outdoors, consider carrying a handheld fan or wearing breathable clothing to stay cool and dry.
- Treat Suspicious Patches Immediately. If you notice circular patches on the skin that resemble ringworm, begin treatment right away to prevent the infection from spreading or worsening. If the ringworm does not improve within three weeks despite using antifungal treatments, consult a doctor for further evaluation.
By following these preventive strategies, you can reduce the risk of ringworm and maintain healthier skin. Early intervention and proper hygiene are key to preventing the spread of this highly contagious fungal infection.
Risk Factors for Ringworm

While anyone can develop ringworm, certain groups are at a higher risk of contracting this skin infection. The likelihood of developing ringworm increases for individuals who fall into the following categories:
- Children. Kids are more prone to ringworm because they often play outdoors and may come into contact with contaminated soil or animals. Additionally, young children may not be as diligent about hygiene practices, making them more susceptible to various skin infections.
- Residents of Warm Climates. Ringworm is more common in countries with hot and humid climates, such as the Philippines. High temperatures and humidity cause excessive sweating, creating an ideal environment for fungi like tinea to thrive. Individuals living in such regions are at a higher risk of developing ringworm.
- Pet Owners. People who have pets, especially cats and dogs, are more likely to get ringworm. Pets can carry the fungus on their fur, especially if they spend time outside. The fungus can easily transfer from an infected animal to a person, making pet owners more vulnerable to ringworm.
- Athletes. Athletes, particularly those who participate in contact sports or activities that cause heavy sweating, are at a higher risk of ringworm infections. This includes common types like athlete’s foot (tinea pedis) and jock itch (tinea cruris). Sweaty clothing and shared facilities, such as locker rooms, can contribute to the spread of the infection.
- People Who Wear Tight or Uncomfortable Clothing. Wearing tight-fitting or non-breathable clothing increases the risk of ringworm. Such garments trap sweat and heat against the skin, creating a breeding ground for fungi. Looser, breathable fabrics can help reduce this risk.
Awareness of these risk factors can help in taking preventive measures to avoid ringworm, such as maintaining good hygiene, avoiding close contact with infected animals or people, and choosing appropriate clothing.
