I recently viewed a TED lecture by Larry Brilliant on stopping pandemics.
http://www.ted.com/talks/larry_brilliant_wants_to_stop_pandemics.html
Larry Brilliant was a part of the smallpox eradication team that was responsible for the global eradication of smallpox (1967-1980). This was one of the greatest accomplishments in public health. His message for disease control now as then is “early detection, early response.”
He advocates for innovative surveillance systems for early detection such as the Global Public Health Intelligence Network (GPHIN), an organization that monitors internet media sources in seven languages to detect events of public health significance . Early detection is vital to successful early response .
