In September, the Davao City Health Office (CHO) confirmed that water sampling from the Davao River that was submitted to Research Institute for Tropical Medicine (RITM) for analysis and tested positive for circulating vaccine-derived poliovirus type 2.
No human infections have been reported in Davao.
Health officials say the revival of type 2 polio virus is due to the poor environmental sanitation, including open defecation in the city.
In response, the CHO will commence a polio vaccination campaign on Oct. 14. Dr. Julinda Acosta, chief of the Technical Division of the CHO said children from zero to 59 months old must be vaccinated starting October 14 in all places of convergence in Davao City.
Parents are urged to have their children vaccinated with polio vaccine type 2, an oral polio vaccine that is employed through two drips in the mouth.
Two human polio cases (VPDV2) were reported in the Philippines last month in a three-year-old girl from Lanao del Sur and a five-year-old boy from Laguna.
The last known case of wild poliovirus recorded in the Philippines was in 1993. The country was declared wild polio-free in 2000.
