Diagnosis, prevention and treatment of fungal infections.

Most fungi live harmlessly in the environment, but some species can cause disease in the human host. Nurses working in primary care are likely to see patients with superficial fungal infections and are well placed to offer advice about treatment and measures to prevent the spread of infection in the home. Patients with weakened immune function admitted to hospital are at high risk of developing serious, invasive fungal infections. Systemic fungal infections are a major problem among critically ill patients in acute care settings and are responsible for an increasing proportion of healthcare-associated infections.
