Emerging infectious diseases are diseases whose incidence has increased within the past two decades and threatens to increase in the new future. Types of emerging diseases include:
- New disease caused by a newly identified microorganism or newly identified strain of a known microorganism (new disease, new microorganism) (e.g., SARS, AIDS; HIV Medicine 2005)
- New infections resulting from changes or evolution of existing organisms (e.g., influenza; Influenza Report)
- Known infections spreading to new geographic areas or populations (e.g., West Nile virus infection)
- Previously unrecognized infections appearing in areas undergoing ecologic transformation
- Old infections reemerging as a result of antibiotic resistance in known agents or breakdowns in public health measures. (e.g. Tuberculosis, although this example can be disputed)
