MANILA (Reuters) - The Philippines is preparing to vaccinate millions of children against polio to halt an outbreak of a disease it believed to have been eradicated two decades ago, a top official said on Friday.
Next month's programme, following the detection of the virus in a three-year-old girl, comes as the Philippines grapples to tackle twin outbreaks of dengue and measles that have killed more than 1,000 people since January, most of them children.
"The polio vaccinations happen all year round, but our coverage dropped for the past five years," Rolando Enrique Domingo, an undersecretary of the Department of Health, told Reuters.
"We've learned our lesson. It is time to move on and really start vaccinating all kids and make sure we sustain this every year."
Vaccination teams will aim to administer polio drops to every child younger than five, he added.
There is no cure for the virus, which invades the nervous system and can cause irreversible paralysis within hours, but it can be prevented with vaccines.
The virus spreads rapidly among children, especially in unsanitary conditions in underdeveloped or war-torn regions where healthcare access is limited.
Afghanistan, Nigeria and Pakistan are the last three countries where the disease is endemic.
Children nationwide are at risk as long as a single child remains infected, the United Nations agency for children, UNICEF, has said.
The Philippines has faced a challenge recently in convincing parents to vaccinate children after it scrapped a dengue immunisation programme using Sanofi's Dengvaxia in late 2017, following its linkage to child deaths.
More than 800,000 children received the vaccine. The records of 119 dead children are being examined to determine if Dengvaxia was to blame, a panel of medical experts said in March.
The inquiry continues and Sanofi has repeatedly said its vaccine is safe.
The Philippines' latest polio case was confirmed on Monday in Lanao del Sur, one of the country's poorest provinces.
In 2017, Islamic State-inspired rebels occupied a city in the southern province for five months in a battle with the military that displaced hundreds of thousands of people.
The polio virus was detected in the sewage systems of Davao in a nearby province two months ago, and in Tondo, a rundown area of Metro Manila notorious for slum communities.
A vaccine campaign started in August in the historic heart of Manila will be expanded to cover more than 5 million children and go nationwide next year, Health Secretary Francisco Duque said in a speech on Friday.
The last known case in the Philippines had been in 1993, the World Health Organization says.
Immunisation coverage in the Philippines is at 70%, below the recommended rate of 95%, Domingo said, as trust in vaccines declines.
