India has made unprecedented progress against P1 in the last one year. The poliovirus, which caused periodic outbreaks and 95 per cent polio cases till 2006, has been curtailed in West Uttar Pradesh, the epicentre of all polio outbreaks, according to WHO officials.
Not a single case of P1 has been reported for over a year and a half from the core endemic areas of western UP — Moradabad, Bareilly, Badaun and Aligarh sub-divisions.
