India making progress toward polio eradication

India seems to be on the fast track to eradicating polio! From 2009 to 2010, India and Nigeria experienced a 94% reduction in the number of polio cases. In 2010, 42 cases of polio were reported in India. In 2011, only one case has been reported (and that was at the beginning of the year). These huge strides can largely be attributed to increased vaccine coverage among children in endemic areas and in migrant populations.

This is pretty exciting! Results like these really emphasize the exponential decay of the number of infections, thanks to vaccines. I'll try and dig up more information about the specific techniques used to bring about this change.
