Internet: Revolutionizing the Detection of Disease Outbreaks
First, a bit of housekeeping – we are tinkering with the look of the blog and considering moving it to another platform, if you have any feedback about what you like and don’t like, let us know.
Published today in the CMAJ, Early detection of disease outbreaks using the Internet, is worth skimming:
“The Internet…is revolutionizing how epidemic intelligence is gathered, and it offers solutions to some of these challenges. Freely available Web-based sources of information may allow us to detect disease outbreaks earlier with reduced cost and increased reporting transparency. Because Web-based data sources exist outside traditional reporting channels, they are invaluable to public health agencies that depend on timely information flow across national and subnational borders. These information sources, which can be identified through Internet-based tools, are often capable of detecting the first evidence of an outbreak, especially in areas with a limited capacity for public health surveillance.”
The limitations section includes the below list, but I wish they went into much more detail about what the internet is not good for (probably detecting trends among the elderly for example) and more examples of misinterpreting the data. On a related note to using ICTs for surveillance, Jaspal wrote a fairly detail post on Google Flu Trends that you should also check out.
