Highlights

  • On 19 September 2019, the Philippines Department of Health (DOH) declared a polio outbreak after 2 confirmed polio cases of vaccine-derived poliovirus type 2 (VDPV2). Environmental samples taken from Manila and Davao tested positive for both VDPV2 (2), as well as for VDPV1 (5).

  • Circulating VDPV2 (cVDPV2) is highly contagious and expected to spread rapidly due to low level of population immunity against poliovirus type 2.

  • cVDPV2 is considered a public health emergency.

  • DOH is planning 3 vaccination rounds targeting 6,650,308 under-five children with monovalent Oral Polio Vaccine against poliovirus type 2 (mOPV2) in affected areas.

  • Sufficient quantities of mOPV2 for the 1st round arrived in Mindanao on 8 October 2019, sent from the global vaccine stockpile, by the Global Polio Eradication Initiative (GPEI). GPEI also mobilised 14 international consultants, who will work closely together with DOH and health partners in Marawi,
    Iligan, Davao, and Manila to support surveillance, monitoring and immunization efforts.

  • Circulating VDPV1 (cVDPV1) results from persistently low routine immunization coverage.

  • DOH is planning 2 vaccination rounds targeting 2,553,262 under-five children with bivalent Oral Polio Vaccine (bOPV) in the National Capital Region (NCR). Enhanced routine immunization with 3 doses of bOPV as well as inactivated poliovirus vaccine (IPV) nationwide is ongoing.
