What Is An Outbreak?
An outbreak is a sudden increase in occurrences of a disease in excess of what would normally be expected in a defined community, geographical area or season. An outbreak may occur in a restricted geographical area, or may even extend over several countries. The outbreak may last for few days, weeks or even several years.
A single case of a communicable disease long absent from a population or caused by an agent (e.g. bacterium or virus) not previously recognized in that community or area, or the emergence of a previously unknown disease, may also constitute an outbreak.
Disease outbreaks are usually caused by an infection, which is transmitted through person-to-person contact, animal-to-person contact, or from the environment or other media.
Outbreaks may also occur following exposure to chemicals or to radioactive materials. Occasionally the cause of an outbreak is unknown, even after thorough investigation.
