The US now joins a list of nearly 30 other countries with a vaccine circulation inherited polyovirus (CVDPV) identified by WHO, said the Center for Control and Prevention of US Diseases (CDC). Poliovirus found in New York, both from the case of Polyts paralyzed in adults who are not vaccinated at Rockland County in New York and in several samples of wastewater from the community near the patient’s residence, meet the WHO criteria for CVDPV, according to CDC.
This means that polyovirus continues to be transmitted in the Rockland and surrounding areas, the US Health Agency said. The genetic sequence of the virus of patients from Rockland County and wastewater specimens collected in New York has been associated with wastewater samples in Jerusalem, Israel, and London, which shows public transmission, according to the health agency.
CVDPV occurs when local immunity to polyovirus is low enough to allow prolonged transmission of the original weakened virus in the oral polio vaccine, according to CDC. When viruses are circulating and more genetic changes, viruses can regain their ability to infect the central nervous system and cause paralysis, Xinhua news agency reports. “Polio vaccination is the safest and best way to fight this weaken disease and it is very important that people in this community are not vaccinated up to date about polio vaccination immediately,” said Jose R. Romero, Director of the CDC National Center for CDC Immunization and respiratory disease.
