AFP is a complex clinical syndrome with a broad array of potential etiologies that vary remarkably with age.

In 2018, India reported 34,891 AFP cases with the states of Uttar Pradesh (12,359) and Bihar (6,914) states reporting the most cases.

This is a drop of more than 10 percent from 2017 when 39,127 cases were seen in the country.

The last wild poliovirus case in India was recorded on Jan, 13, 2011. Since that time, not a single AFP case has tested positive for polio.
