This study examined fungal skin infections in children and teens in Northern Poland over six years, finding that about 1 in 5 children tested had a fungal infection. Different types of fungal infections were more common at different ages—younger children more often had scalp infections, while teenagers more often had foot and nail infections. The study found that children living in rural areas had higher infection rates than those in cities, suggesting that environmental factors play an important role in fungal infection patterns.
