👉 The term "infection" in the context of wallpaper often refers to a type of mold or fungus that can grow on the surface, particularly in areas with high humidity or poor ventilation. This growth can lead to unsightly spots, discoloration, and a general deterioration of the wallpaper's appearance. Mold thrives in damp environments, making it a common issue in basements, bathrooms, and other humid spaces. While some molds are harmless, others can pose health risks, especially for individuals with allergies or respiratory issues. Preventing infection involves maintaining low humidity levels, ensuring good air circulation, and promptly addressing any water damage to prevent mold spores from taking hold.
