Ringworm is a fungal infection that mainly affects the scalp and skin. It is caused by various types of dermatophyte fungi. The most common symptoms include circular patches, erythema (redness of the skin) and itching. These lesions may also present with hair loss on the scalp, known asalopecia. Diagnosis is usually made by visual examination, and can be confirmed by tests such as fungal culture or direct examination under a microscope.
Ringworm is mainly transmitted by direct contact with fungal spores, which can come from contaminated people, animals or surfaces. Children are particularly susceptible to this infection because of their close play habits and lower resistance to infection. Pets such as cats and dogs can also carry the fungus and transmit it to humans.
Preventing ringworm involves several key measures:
Treatment for ringworm depends on the severity and location of the infection. Treatment options include:
Although ringworm is generally benign, it can cause significant discomfort due to itching and the appearance of lesions. This can affect self-esteem and emotional well-being, particularly in children and adolescents. Prompt and effective treatment is crucial to minimize the psychological and physical impact of the infection.
In rare cases, ringworm can lead to complications such as secondary infections caused by bacteria. These infections may require antibiotic treatment. Immediate medical attention is recommended if the infection worsens or does not respond to the usual treatment.
Ringworm often manifests as round, light-colored patches with a reddish border, which can distinguish it from other conditions such as eczema or psoriasis. Eczema tends to be more diffuse and less well-defined, while psoriasis often presents thick, scaly patches. For a precise diagnosis, it is always advisable to consult a dermatologist, who can carry out a mycological examination to confirm the presence of pathogenic fungi.
Yes, public swimming pools can be a vector for the transmission of ringworm-causing fungi, especially if hygiene is not rigorously controlled. Fungal spores can survive in damp environments and be transmitted by indirect contact. To minimize the risk of infection, we recommend wearing pool shoes and showering before and after using public facilities.
Although ringworm can occur at any time of year, certain seasonal factors, such as increased humidity during the warmer months, can favor the proliferation of fungi. In addition, outdoor activities during the summer months increase interactions between children and animals, two common vectors of this infection. So it's important to maintain good personal hygiene practices all year round.
The duration of ringworm treatment may vary according to the extent of infection and response to drug therapy. In general, topical treatments should be applied for at least 2 to 4 weeks. For more severe cases requiring oral medication, treatment can last from 6 to 8 weeks. It's crucial to follow the health professional's recommendations and not to stop treatment prematurely, to avoid relapses.
Some natural remedies, such as tea tree oil or garlic, have antifungal properties that can help relieve ringworm symptoms. However, their effectiveness can vary, and they generally do not replace drug treatments prescribed by health professionals. They can be used as a complement, but it is advisable to consult a doctor before initiating any natural treatment to ensure its safety and efficacy.
