Fungal infections are caused by fungi, which are tiny organisms that can be found in the environment, including soil and 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. Fungi thrive in warm, moist areas, making certain individuals more susceptible, especially those with weakened immune systems. Treatment for fungal infections often involves antifungal medications, which can be topical (applied to the skin) or systemic (taken orally). Prevention includes maintaining good hygiene, keeping skin dry, and avoiding close contact with infected individuals. Understanding the nature of fungal infections can help in managing and preventing them effectively.
