(CNET)  Google on Tuesday unveiled a new site to track the progress of the common cold.

Using the same keyword tracking technology found on Google Trends, it keeps an eye on people searching for queries involving the word "flu" and tracks them both by date and location.

What makes the technology so fascinating is that its data set goes back to 2003, and has been cross-referenced with the last several years of survey data from the Centers for Disease Control and Prevention (CDC). Google says that because its own system is based on a constant flow of searches as opposed to surveying techniques it's able to provide results one to two weeks faster than the CDC.

The same trending technique could be used in tandem with other organizations to track contagious viruses or threats besides the common cold, including AIDS, bird flu, and Africanized honey bees.

One limitation of the current system is that it does not track worldwide flu traffic. There is, however, quite a bit to discover from data from years prior--especially when you get several years that stack up on top of each other with similar rises and falls during certain parts of the year. According to Google's chart, we're about three weeks from hitting the heavy season, which goes until early January.

This only works when the searcher uses the correct medical semantics and specific clinical terminology. The term -muscle aches- does not equal -flu outbreak-.
There was actually a task force sponsored by Consumers Union and HHS/Disease Prevention several years ago that studied this, found Google searching was too uncontrolled and random to actually predict an outbreak (see: http://www.urac.org/savedfiles/URAC_CWW_Health_Search_White_Paper1203.pdf).

And a keyword like "explosives" will do what? Or "assassination?" Or "jeremiah wright?" How about "Paulson-pervert-pedophile-pornography?" Or "Dubya-moron-liar?" What will they tell whom and for what purpose? Does google care? Do we?

In "Related Stories" there is a link titled "Pregnant Mom''s flu shot protects baby."

Sure, mom''s immune system transfers to baby, but so does the mercury the U.S. puts into their flu shots. This is credited with the amazing, unprecedented rise in autism in the United States.

This is so laughable, everyone should run search on the flu ever day, see how useful the technology is then.
