What do all of these headlines have in common? Not only are they are all from recent newspaper stories, each of them refers to similar events from around the globe.
As this activity is being written, our world is experiencing the beginnings of an outbreak COVID-19, a flu-like disease caused by the virus SARS-CoV-2. The more we can understand about how disease outbreaks like COVID-19 are similar, the better we will be at managing and mitigating the impacts of infectious disease in a world of ever increasing population.
It is a principle of systems thinking to assume that there is always more to an event than what meets the eye. Like an iceberg, there is often a huge amount of unseen pattern and structure lying beneath the surface of any event.
The news stories associated with all of these headlines follow a pattern of cause and effect. In all cases multiple individuals suffer from a disease, and in all cases the disease turns up in groups that share a common living space and undergo continual contact with others of the same group. Each case is referred to as an “outbreak,” barely noticeable at first and suddenly rising to the level of an epidemic in a short period of time.
Could it be that these similar events, all showing similar patterns, are linked by common systemic structures that drive their behavior? And if they are, could knowledge of those structures prove useful when designing policies that could help prevent and manage similar outbreaks in the future? These are the kinds of questions that system models can help to answer.
