Emerging Infections

Fruit Bat

Over the past 25 years, more than 30 new or newly-recognised infections have been identified around the world.

The pattern of known infections also changes constantly, as the areas where disease is constantly present expand beyond traditional limits.

Emerging infections may be:

  • A recognised infection spreading to new areas or populations
  • The result of discovering that a known disease is caused by infection
  • A previously unrecognised infection appearing in areas where the habitat is changing (e.g. deforestation)
  • A new infection resulting from change(s) in existing microorganisms
  • An "old" infection re-emerging because it has become resistant to treatment, or as a result of a breakdown in public health initiatives.
