Disease outbreak news from the WHO: Polio outbreak– The Philippines

On 19 September 2019, the Philippines declared an outbreak of polio. Two cases have been reported to date, both caused by vaccine-derived poliovirus type 2 (VDPV2). Environmental samples taken from sewage in Manila on 13 August and a waterway in Davao on 22 August have also tested positive for VDPV2.

The first case was confirmed on 14 September following testing by the National Polio Laboratory at the Research Institute for Tropical Medicine, the Japan National Institute of Infectious Diseases (NIID) and the United States Centers for Disease Control and Prevention (CDC). The case-patient is a 3-year-old girl from Lanao del Sur in the southern Philippines. The virus isolated is genetically linked to VDPV2 previously isolated from environmental samples in Manila and Davao. This indicates that the virus is circulating.

The second case was confirmed on 19 September and is a 5-year-old boy from Laguna Province, approximately 100 km south-east of Metro Manila. Investigations and further characterization of the virus are ongoing.

In addition, VDPV1 has also been isolated from environmental samples collected on 1 July, 22 July, 13 August, and 27 August from Manila.
