Fungal infections can manifest as redness, itching, or flaky skin, and may occur in warm, moist areas of the body. They are caused by fungi present in the environment, which can thrive under certain conditions. To manage these infections, maintaining good hygiene is essential, along with wearing breathable clothing. Over-the-counter antifungal creams can be effective for mild cases. However, if symptoms persist or worsen, it is wise to consult a dermatologist for appropriate diagnosis and treatment.
