Figure 9.2
Within a couple of minutes from loading the data, the analysts found an emerging leptospiro-
sis event in the southwestern and central provinces of Sri Lanka. Spatial scan algorithm tracks
probabilities of leptospirosis outbreak anywhere in the nation for all days in the past data. On
August 18, 2008, it went over 97%. Dark bars in the time-series plot and dark circles in the map
depict the temporal and spatial distribution of the volume of patients diagnosed with the disease.
