A new study titled Correlation between Non-Polio Acute Flaccid Paralysis Rates with Pulse Polio Frequency in India has recently been published in the Journal of Environmental Research and Public Health. Using data obtained from the National Polio Surveillance Programme (NPSP) as reported by the Government of India, the findings corroborate well over a decade of research showing a strong link between rates of non-polio acute flaccid paralysis (NPAFP) and India's oral polio vaccine (OPV) campaign. The incidence of polio acute flaccid paralysis (AFP) in India has decreased. However, the NPAFP rate has increased since 2000.
