Thursday, February 26th, 2026 - Health officials across the United States are increasingly concerned about a surge in cases of ringworm, a common fungal infection, with a particularly alarming trend towards sexual transmission and the emergence of drug-resistant strains. While ringworm - despite its name - isn't caused by worms, but by a fungus, the way it's spreading and its growing resistance to treatment are prompting a public health response.

Beyond Pets: The Shifting Landscape of Ringworm Transmission

Traditionally, ringworm (dermatophytosis) was most often contracted through contact with infected animals like cats and dogs, or from contaminated surfaces. Children were particularly vulnerable. However, recent data indicates a significant shift. While animal transmission remains a factor, a growing number of cases are linked to person-to-person contact, specifically through intimate encounters and activities involving close physical proximity. This includes a concerning rise in sexually transmitted cases, as well as outbreaks in athletic settings like gyms, locker rooms, and wrestling facilities.

Trichophyton mentaglyphytes is the primary fungal species driving this outbreak. This strain is proving difficult to treat with standard antifungal medications in many cases, raising the specter of widespread, untreatable infections if the trend continues. The Centers for Disease Control and Prevention (CDC) has issued preliminary guidance urging healthcare providers to be vigilant for unusual or treatment-resistant skin infections.

Symptoms and Identification

The hallmark symptom of ringworm is a characteristic itchy, scaly, circular rash that resembles rings on the skin - hence the name. However, the presentation can vary. Lesions can appear anywhere on the body, including the groin, thighs, feet (athlete's foot), scalp, and even nails. Symptoms include:

• Intense itching
• Red, inflamed skin
• Scaly or flaky patches
• Circular or oval-shaped rashes with raised borders
• Hair loss in affected scalp areas
• Blisters or pus-filled sores (especially if a secondary bacterial infection develops)

Diagnosis typically involves a skin scraping test, where a small sample of affected skin is examined under a microscope to identify the fungus. Rapid diagnostic tests are also becoming increasingly available, allowing for quicker identification and targeted treatment.

The Threat of Drug Resistance

The most pressing concern surrounding this outbreak is the emergence of antifungal resistance. Many common over-the-counter and prescription antifungal creams and oral medications are proving ineffective against certain strains of Trichophyton mentaglyphytes. This means infections are lasting longer, spreading more easily, and requiring more aggressive - and potentially toxic - treatments. Researchers are actively investigating the mechanisms behind this resistance, which may involve genetic mutations in the fungus.

Prevention and Treatment Strategies

Preventing the spread of ringworm requires a multi-pronged approach. Public health officials recommend:

• Strict Hygiene: Frequent handwashing with soap and water is crucial, particularly after contact with public surfaces or potential sources of infection.
• Avoid Sharing Personal Items: Towels, clothing, razors, and other personal care items should not be shared.
• Clean and Disinfect: Regularly disinfect surfaces in gyms, locker rooms, and other communal areas.
• Safe Sexual Practices: Practicing safe sex, including the use of barrier methods, can help reduce the risk of transmission.
• Prompt Medical Attention: Anyone suspecting they have ringworm should consult a doctor immediately for diagnosis and appropriate treatment.

Treatment typically involves antifungal medications, either topical creams for mild infections or oral medications for more severe or widespread cases. However, given the growing resistance, doctors may need to utilize more potent - and potentially more expensive - antifungal drugs. In severe cases, hospitalization may be required.

The Road Ahead

The rise in sexually transmitted and drug-resistant ringworm represents a significant public health challenge. Continued surveillance, research into antifungal resistance, and public awareness campaigns are essential to contain the outbreak and protect the population. Experts emphasize the importance of early detection and treatment to prevent further spread and the development of more resistant strains. The CDC is expected to release more detailed guidance and recommendations in the coming weeks.
