Officially declare, if not already done, at the level of head of state or government, that the prevention or interruption of poliovirus transmission is a national public health emergency

  • Undertake urgent and intensive investigations to determine if there has been local transmission of the imported cVDPV2
  • Noting the existence of a separate mechanism for responding to type 2 poliovirus infections, consider requesting vaccines from the global mOPV2 stockpile based on the recommendations of the Advisory Group on mOPV2.
  • Further intensify efforts to increase IPV immunization coverage, including sharing coverage data.
  • Intensify national and international surveillance regional cooperation and cross-border coordination to enhance surveillance for prompt detection of poliovirus.
