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.

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

Variable	Treatment	Description
Location	Break into "Lat" and "Lon" respectively	SAS EG workflow to prepare Lat/Lon and save to library
Text	Find stemmed words from text	SAS EM workflow to extract stemmed words from library. This will help avoid fuzzy lookup e.g. I search for "ache" but "mustache" is returned
Text	Filter microblogs to only pre-defined symptoms	SAS EG workflow to join documents and words list. Note that these are all stemmed words so whatever forms of words are in the microblogs, even misspelled ones, will be detected.
Symptom	Group symptoms into 3 broad categories: related to digestive system, respiratory system or muscle
