Only Pakistan, Afghanistan and Nigeria (in the entire world) have wild polio virus in active circulation. One might think the disease could be contracted from the virus circulating in neighbouring countries, but Dhariwal clarifies that any cases or deaths would actually be attributed to the virus being contracted years ago and lying dormant.

The last polio case in India was recorded in West Bengal in 2011. In Delhi, the last case was reported in 2009. The World Health Organisation declared India polio-free since 2014.
