In the germ world, fungi usually lack the flair of viruses or bacteria. To people with normal, healthy immune systems, a fungus will rarely show itself — even though you carry around a microscopic film of fungus on your hair and skin, and take in invisible clouds of fungal spores with each breath. While many other microbes prefer to make a living through disease and death, a fungus is often content to wait for its host to die of something else.
