Sn-hepatitis.jpg Disease Outbreak Investigation

Objective & Methodology

In light of the serious situation that Smartpolis faces (several deaths reported!), I need to:

1. Source: Determine origin of disease outbreak

2. Spread: Find out medium of transmission

3. Control: Suggest measures to contain spread

My approach to this problem is:

Action Step Result
Filter blog text for spots of flu Exclude non-disease blogs from analysis
Determine type of symptoms Categorise symptoms into water, air or human
Correlate spots with map and time Animate disease outbreak path by timelapse
Drill down into water-borne Study the origin, spread and contributing factor
Drill down into air-borne Study the origin, spread and contributing factor
Drill down into human-transmitted Study the origin, spread and contributing factor

So that I can suggest containment measures and geo-fencing for each of the transmission type.


Data Preparation

Efforts are needed to transform the "Microblog" dataset into a format that is conducive for visualization.

Variable Treatment Tool Remark
Location Break into "Lat" and "Lon" respectively SAS EG
SAS EG workflow to prepare Lat/Lon and save to library
Text Find meaningful symptoms SAS EG According to pre-defined list of common symptoms
