Google searches can predict the flu!!

Holy COW! I'm probably the last person in public health to know this, but the rate of google searches for "flu" closely matches the actual incidence of flu! I didn't read the journal article (yet) but you have GOT to look at this--it's amazing. The implications are huge. Google search as a surveillance tool is actually a really great idea!

"Google Flu Trends estimates flu activity for a number of countries by using aggregated search query data. The system provides users and public health officials with near real-time estimates of flu activity in their region. Traditional surveillance reports come directly from doctors and other health service professionals, sometimes with a delay of up to 1-2 weeks."

Biological Warfare: "1491" by Charles C. Mann

An amazing read! Charles C. Mann's book "1491" describes the possibility that native American contact with European traders may have depopulated the continent in advance of the arrival of colonists via spread of disease. Hence, when the colonists arrived, they found a relatively sparsely populated countryside. This context then gives rise our cultural imagination of the native population as 'primitives' living in a relatively uncultured and somewhat 'ecologically harmonious' and naive state.

Biological relativism is also debunked in Appendix C. European disease obliterated native American cultures, and the natural question arises--what diseases originated on this continent that had the same effect on Europeans? One oft-repeated answer: syphilis. The first recorded European outbreak of syphilis occurred around 1494-1495, brought back by mercenaries working for Charles VIII of France's armies in their conquest of Naples. As Charles' army fled a counter attack, mercenaries split off from the main retreating body, spreading syphilis as they went via their habit of rape and pillage. Within a year, European cities were banishing people who suffered from syphilis. It's not clear whether the disease came from American with Columbus' returning voyage, as suggested, with an equal number of arguments for and against. Hence any positive assertion of biological symmetry is sketchy at best. Mann makes the point that while smallpox toppled empires, syphilis did not, even if it did come from the Americas.

This book is interesting beyond the war-health perspective and will debunk many myths built up from years of TV, Hollywood movies, childhood fiction, and junior high text books.
