Department of Health (DOH) Philippines, 19 September 2019
On 19 September 2019, the Department of Health (DOH) confirmed the re-emergence of polio in the Philippines and declared a national polio outbreak. This follows a confirmed Vaccine Derived Poliovirus Type 2 (VPDV2) case in a three-year old child in Lanao de Sur (Mindanao). The re-emergence of the disease comes almost 20 years since the Philippines was declared polio-free in 2000. The last known case of wild poliovirus recorded in the Philippines was in 1993. Between 1 July and 27 August 2019, four (4) environmental samples tested positive for VPDV 1 from Tondo (Manila), with no genetic linkage found with any known VDPV1 indicating new emergence. Between 13 and 22 August 2019, two (2) environmental samples tested positive for VDPV2 from Tondo (Manila) and Davao City. Both samples were founded to be genetically linked. As a result, VDPV2 was classified as circulating (cVDPV2).
