Fungus is an important part of the breakdown of decaying material, but what happens when that fungus infects a healthy human body? While some infections may look bacterial or viral, young readers will be surprised to learn that they can actually be from fungus. Fungal infections are common, leading to conditions like athlete's foot and ringworm. Understanding how these fungi are spread can help young readers learn how to remain fungi-free. With photographs of fungi in action and fun illustrations to keep the topic light, this book keeps young readers interested in the science of fungal infections.
