Fungal infections are caused by tiny organisms called fungi, which can be found in the environment, including soil and decaying plants. These infections can affect various parts of the body, such as the skin, nails, and lungs. Common types include athlete's foot, ringworm, and yeast infections. While many fungi are harmless, some can lead to serious health issues, especially in people with weakened immune systems. Treatment for fungal infections often involves antifungal medications, which can be topical (applied to the skin) or systemic (taken orally). It's important to maintain good hygiene and keep the skin dry to prevent these infections. If symptoms persist, consulting a healthcare professional is essential for proper diagnosis and treatment.
