World Health Organization update on suspected polio case in Venezuela


Source: MercoPress



Following unconfirmed reports on 8 June of suspected polio re-emergence in Venezuela, final laboratory testing has confirmed the cause of the paralysis is not wild poliovirus or vaccine-derived poliovirus, according to a release from WHO.

A 34-month old child had presented with symptoms of acute flaccid paralysis (AFP) on 29 April, from a community with low vaccination coverage in Orinoco delta, Delta Amacuro state.

A Sabin type 3 poliovirus was isolated from stool samples of the child. Isolation of Sabin type 3 poliovirus can be expected in children and communities immunized with bivalent oral polio vaccine, which contains attenuated (weakened) type 1 and type 3 Sabin strains. Final laboratory analysis received on Friday has confirmed that the AFP symptoms are not associated with wild or vaccine-derived poliovirus.
