The official response to the polio case in India has been delayed

The case of acute limp palsy, probably due to polio, in a child from Tikrikilla in Meghalaya, and in the media limelight, was reported by the State government on August 14. In April 2022, a case of vaccine- deduced poliovirus was detected from an environmental sample collected in Kolkata.

After inheritable sequencing, it was considered likely to be immunodeficiency- related vaccine- deduced poliovirus( iVDPV), excreted by an vulnerable-deficient existent. In the Meghalaya incident, indeed after the government verified the case, there’s still no sanctioned report on whether it’s vaccine- deduced and not caused by wild poliovirus. With the global eradication of the wild poliovirus( WPV) type 2 in 2015 and the WPV type 3 in 2019, independently, and no WPV type 1 set up in terrain samples in India for times, it’s largely doubtful that it’s due to the WPV type 1 unless it has been imported into India. As of August 13, Afghanistan and Pakistan have reported 14 WPV type 1 cases this year.

However, there’s again no sanctioned evidence on whether it’s iVDPV or from circulating vaccine- deduced poliovirus( cVDPV), If vaccine- deduced. This information is crucial as cVDPV would mean that the contagion is in rotation in the community, while iVDPV is confined to the single immunodeficient child. Also puzzling is the absence of any sanctioned report on whether the case has been caused by the type- 1, type- 2 or type- 3 vaccine- deduced contagion. India made the encyclopedically synchronised switch in 2016 from trivalent to bivalent oral polio vaccine that has only live, downgraded type 1 and type 3 contagion. So, while it’s insolvable that the child has the type 2 contagion from the oral vaccine given in India, the chances of cVDPV type 2 contagion imported into India can not be ruled out.

In 2024, 68 cVDPV2 and four cVDPV1 cases were recorded encyclopedically. numerous countries have reported cVDPV in terrain samples. The long detention in attesting these pivotal details is interesting as samples from the child were transferred to the ICMR- NIV Mumbai unit, which is a part of the WHO network of 146 accredited polio laboratories worldwide and conducts exploration on conditions caused by enteroviruses, especially paralyzed poliomyelitis and acute limp palsy. Unlike in the case of IPV, immunodeficient children are n’t supposed to be administered OPV.

Since relating similar children previous to administering OPV is a challenge in India, India will continue to have similar cases in the future. The Meghalaya case again brings into focus the critical need for India to stop using OPV and switch over simply to IPV. utmost advanced countries switched to IPV decades ag0 ,There’s no reason why India should n’t switch to IPV at the foremost.
