The Region of the Americas this year is celebrating 26 years with no cases of wild poliovirus. The last case was detected on August 23, 1991, in Peru. The countries of the region, supported by the Pan American Health Organization/World Health Organization (PAHO/WHO), were able to eliminate polio and maintain the Americas free of the disease by achieving high rates of vaccination coverage of children and through sustained epidemiological surveillance to ensure early detection of any outbreaks.
Poliovirus is still circulating in three countries of the world. PAHO says, until polio is eradicated everywhere, the global population will continue to be at risk.
