Alerts in North America
On September 13, 2022, the United States of America announced that polioviruses found in New York, both in the case of paralytic polio in an unvaccinated adult in Rockland County, and in several sewage samples from communities near the patient´s residence, meet the criteria for circulating vaccine-derived poliovirus (cVDPV). Given this situation, the Pan American Health Organization/World Health Organization (PAHO/WHO) reiterates to the Member States the need to have an updated response plan for polio outbreaks or events, join efforts to strengthen and maintain surveillance epidemiology of acute flaccid paralysis for the rapid detection of cases, and to achieve vaccination coverage against poliomyelitis >95%.
