Briefly discuss common source outbreaks.
What will be an ideal response?
In a common source outbreak, all cases of the infectious disease are acquired from the same source in a limited period of time and in a limited geographical location. It's also characterized by very minimal (or zero) transmission from person to person. Generally, a common source outbreak has a smaller number of cases than a propagated outbreak and is often caused by contaminated food or water. Common source epidemics are usually characterized by a dramatic single "peak" of cases. Many common source outbreaks go unreported since they are generally small in numbers and often don't come to the attention of public health authorities.
