Is polio re-emerging in Venezuela nearly 30 years after eradication?
Source: CNN
(CNN)A child has been diagnosed with a common symptom of polio in Venezuela, where the infectious viral disease has been eradicated since 1989, according to the Pan American Health Organization, a regional apparatus of the World Health Organization. The Western Hemisphere has been certified polio-free since 1994.
In a statement to CNN, the WHO said, "an acute flaccid paralysis case is currently being investigated" in the state of Delta Amacuro, Venezuela. Acute flaccid paralysis is a sudden onset of weakness in or loss of the ability to move any part of the body of a child less than 15 years of age. Until additional laboratory results are received, polio cannot be confirmed, the WHO said.
"Final results are expected over the coming weeks. Acute flaccid paralysis is caused by a number of different causalities, poliovirus being just one of them," according to the WHO.
This diagnosis of acute flaccid paralysis in a child comes as Venezuela, with an estimated population of 31.3 million, experiences political and economic turmoil, resulting in a humanitarian and health care crisis.

I'll wait for lab confirmation and wish that CNN would too.

Vaccine-derived polioviruses (VDPVs) are rare strains of poliovirus that have genetically mutated from the strain contained in the oral polio vaccine. The oral polio vaccine contains a live, attenuated(weakened) vaccine-virus. When a child is vaccinated,the weakened vaccine-virus replicates in the intestine and enters into the bloodstream, triggering a protective immune response in the child. Like wild poliovirus, the child excretes the vaccine-virus for a period of six to eight weeks. Importantly, as it is excreted, some of the vaccine-virus may no longer be the same as the original vaccine-virus as it has genetically altered during replication. This is called a VDPV.

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.
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 today has confirmed that the AFP symptoms are not associated with wild or vaccine-derived poliovirus.
