Fungal infections are surprisingly common and can affect anyone, regardless of age or hygiene habits. One of the most well-known and widespread fungal infections is ringworm—and despite its name, it has nothing to do with actual worms. So, why do people get fungal and ringworm infections, and where exactly do these annoying (and sometimes embarrassing) conditions come from?
Let’s dive into the causes, sources, prevention tips, and treatment options in a friendly, easy-to-understand way.
What Is a Fungal Infection?
A fungal infection occurs when fungi—a group of organisms including yeasts, molds, and mushrooms—invade the body, usually the skin, nails, or mucous membranes. Some fungi naturally live on our skin without causing problems. However, under certain conditions, these fungi can multiply and cause infections.
Common types of fungal infections include:
-
Athlete’s foot (tinea pedis)
-
Jock itch (tinea cruris)
-
Nail fungus (onychomycosis)
-
Yeast infections (Candida species)
-
Ringworm (tinea corporis)
These infections are more common than you might think, especially in warm, humid environments or among people who are very active.
What Exactly Is Ringworm?
Despite the name, ringworm has nothing to do with worms. It’s actually a skin infection caused by a type of fungus known as a dermatophyte. The name “ringworm” comes from the circular, ring-like rash that appears on the skin. It’s red, itchy, and may have a clear center with a more defined border.
There are several types of ringworm based on the part of the body it affects:
-
Tinea corporis: Ringworm of the body
-
Tinea capitis: Scalp ringworm
-
Tinea pedis: Athlete’s foot (feet and toes)
-
Tinea cruris: Jock itch (groin area)
-
Tinea unguium: Nail fungus
How Do People Get Ringworm and Other Fungal Infections?
Fungal infections, including ringworm, are highly contagious and can spread through several different sources. Let’s break down how people commonly get infected:
1. Person-to-Person Contact
This is one of the most common ways fungal infections spread. You can catch ringworm just by touching someone who has an active infection. This is especially common in families, school settings, gyms, and sports teams where skin-to-skin contact is frequent.
2. Animal-to-Human Transmission
Pets can carry ringworm, especially cats and dogs. Farm animals like cows, horses, and goats can also carry the fungus. If you cuddle with a pet that has a patch of missing fur or scaly skin, you could easily pick up the infection.
3. Contaminated Objects
Fungi can survive on surfaces for a surprisingly long time. You might get infected by using a towel, hairbrush, hat, or even gym equipment that has been used by someone with ringworm. This is why sharing personal items is a big no-no when it comes to preventing infections.
4. Environment (Soil and Surfaces)
You can also get ringworm from the environment, particularly in moist, warm places. Fungal spores thrive in areas like locker rooms, public showers, swimming pool areas, and even soil. Walking barefoot in these places increases your risk.
Who Is at Risk of Ringworm and Other Fungal Infections?
Fungal infections can affect anyone, but certain people are more susceptible. These include:
-
Children (especially those in daycare or school)
-
Athletes (due to sweating and close contact)
-
People with weakened immune systems
-
Those living in warm, humid climates
-
Individuals with poor hygiene or skin injuries
-
People who wear tight or non-breathable clothing regularly
Signs and Symptoms of Ringworm and Fungal Infections
Recognizing the early signs can help with faster treatment and less spreading. Here’s what to watch out for:
For Ringworm:
-
Red, circular patches with raised edges
-
Itchy skin
-
Cracking, peeling, or scaling of the skin
-
Blisters or pustules around the rash
-
Hair loss in the affected area (especially on the scalp)
For Other Fungal Infections:
-
Itching or burning (especially in the groin or feet)
-
Thickened or discolored nails
-
Odor (common with athlete’s foot)
-
Red or inflamed skin
If you think you might have ringworm or another fungal infection, it’s best to consult a doctor or dermatologist for a proper diagnosis.
How to Treat Ringworm and Fungal Infections
The good news? Fungal infections like ringworm are treatable! Most cases can be managed with over-the-counter (OTC) antifungal creams, sprays, or powders. In more severe or stubborn cases, your doctor may prescribe oral antifungal medications.
Common OTC Treatments Include:
-
Clotrimazole (Lotrimin)
-
Miconazole (Micatin)
-
Terbinafine (Lamisil)
-
Tolnaftate (Tinactin)
How to use these treatments:
-
Clean and dry the affected area thoroughly.
-
Apply the antifungal as directed (usually twice daily).
-
Continue using the product for a few days after symptoms disappear to prevent recurrence.
For scalp ringworm or severe nail infections, oral medications may be necessary. These include griseofulvin, fluconazole, or itraconazole.
Can Ringworm Go Away on Its Own?
In very mild cases, a healthy immune system might eventually clear up the infection. But in most cases, ringworm will not go away without treatment—and it can actually spread or worsen over time. Treating it promptly is the best way to prevent discomfort and stop the spread to others.
How to Prevent Fungal and Ringworm Infections
Prevention is always better than cure. Here are some practical ways to avoid catching or spreading ringworm and other fungal infections:
1. Keep Skin Clean and Dry
Fungi thrive in warm, moist environments. After showering or sweating, make sure to dry off completely, especially in skin folds or between your toes.
2. Don’t Share Personal Items
Avoid sharing towels, razors, socks, shoes, hats, and grooming tools—especially in communal settings like locker rooms or dorms.
3. Wear Breathable Clothing
Choose moisture-wicking fabrics, especially if you’re working out or in a hot climate. Change out of sweaty clothes as soon as possible.
4. Wash Hands Frequently
Good hand hygiene helps prevent the spread of fungi and other infectious agents.
5. Clean and Disinfect Common Areas
Regularly clean gym equipment, mats, and bathroom surfaces. If you have pets, keep their bedding and living areas clean too.
6. Treat Infected Pets
If your pet shows signs of ringworm, take them to the vet right away. Treating both the pet and the environment will help stop the cycle of infection.
Is Ringworm Dangerous?
Most cases of ringworm are not serious and respond well to treatment. However, if left untreated, it can spread to other parts of the body or other people. In people with weakened immune systems, a fungal infection could lead to more serious complications. That’s why early detection and treatment are important.
Common Myths About Ringworm
❌ “Only dirty people get ringworm.”
Not true! Anyone can get ringworm—even the cleanest people. It’s about exposure to the fungus, not poor hygiene.
❌ “Ringworm is caused by a worm.”
Nope. It’s a fungus, not a worm. The name comes from the circular shape of the rash.
❌ “You can’t get ringworm from pets.”
Actually, pets—especially cats and dogs—are common carriers of the ringworm fungus.
Conclusion
Fungal infections like ringworm are common, treatable, and preventable. Understanding where they come from and how to protect yourself can go a long way in keeping your skin (and others’) healthy and itch-free.
If you or a family member develops signs of ringworm, don’t panic. Prompt treatment with antifungal medication and good hygiene practices can quickly clear up the infection and prevent it from spreading. And remember: when in doubt, it’s always smart to consult a healthcare professional for proper diagnosis and treatment.
So the next time you hear someone ask, “Where did this come from?” about an itchy rash, you’ll be ready with answers—and probably a good prevention tip or two.
