Cases of disease caused by wild poliovirus in 2023 were reported in Afghanistan and Pakistan, which, in case of declining vaccination coverage, may lead to the introduction of wild virus into currently polio-free country. This study presents information about various sources VDPV. VDPV were found in environmental objects worldwide and were found to be a major cause of acute flaccid paralysis. The information about poliovirus circulation in this article confirms the need to maintain high immunization coverage with trivalent IPV, to develop m-OPV2 production for rapid outbreak response, and to improve epidemiological surveillance methods. |
