When did the Epidemic Start
The total number of messages was plotted across time, differentiating between sick (indicated as "1") and non-sick (indicated as "0") messages. Figure 1 shows a sharp spike in sick related messages from 18 May 2011 onwards. Since symptoms of the virus spreads take some time to manifest, we may conclude that an incident preceding to the start of the epidemic (i.e. prior to 18 May 2011) and look for clues of where the disease may have started from.
Where did the Epidemic Start
IDs with sick messages are plotted on the map and played through the dates, particularly on 16 May 2011, 17 May 2011 and 18 May 2011. The number of sick messages on 17 May 2011 was consistently low as per the previous says. However, on the morning of 18 May 2011, at 8.10am, a noticeable cluster of sick messages are observed near the bridge of expressway 610 as displayed in Figure 2 below.
With both clues, we may speculate that an incident may have occurred near bridge 610 that potentially resulted in the start of the endemic.
From the word cloud of text messages, we have gleaned the major events that occurred prior to 18 May 2011. There was only incident that stood out from the rest due to its proximity with bridge 610 and day that the endemic started. This was a truck collision before noon of 17 May 2011 on bridge 610.
Refer to Figure 3 for the word cloud on 17 May 2011 that provides clues on Ground Zero.
Netizens reported the following regarding the incident:
With such information from the messages, we may hypothesize the following:
- Fire from the truck accident may have released fumes that spread to netizens working in the vicinity of bridge 610
- Contents of the trucks tipped over and may have fallen into the river
We shall explore these hypotheses in the next section on "Transmission Mode".
