Contact tracing is a crucial tactic in reducing the spread of communicable diseases such as COVID-19. It’s used to break the chain of transmission by identifying people who have been exposed to an infected person so that they can take necessary steps to isolate themselves, or if they are already showing symptoms, begin treatment.
Used for decades as an attempt to stave off a variety of communicable diseases, it is a manual, resource-intensive and effort to identify the points of transmission and slow community spread. Fortunately, data visualization and analytics can be used to assist public health officials in uncovering insights from contact tracing and publicly available health data to understand:
• Missing or unexpected linkages.
• Who should be tested.
• Where the virus is spreading.
• Which communities are at greatest risk.
