WHO: Syrian polio outbreak risks spreading
Print Edition
Polio has broken out among young children in northeast Syria and could spread inside and outside the country, where civil war has led to falling vaccination rates, the World Health Organization warns.
The highly contagious crippling disease, transmitted via contaminated food and water, can spread rapidly among children under five, especially in unsanitary shelters for the displaced in Syria or crowded refugee camps in neighboring countries.
Twenty-two children in Deir al-Zor province bordering Iraq became paralyzed on October 17. WHO’s regional laboratory in Tunis has isolated the wild polio virus in samples taken from 10 victims. Results on the other 12 are expected within days.
“Out of those 22 being investigated, 10 are now confirmed to be due to polio virus,” Oliver Rosenbauer, spokesman of the WHO polio eradication program, told a news briefing in Geneva yesterday.
Most victims are under two years old and are believed never to have been vaccinated or to have received only a single dose of the oral vaccine instead of the three which ensure protection from polio, he said.
It is Syria’s first polio outbreak since 1999, according to the United Nations agency.
“Immunizations have started in that area,” Rosenbauer said.
The city of Deir al-Zor is partially controlled by Syrian government forces while the surrounding countryside is in the hands of rebels fighting to remove President Bashar al-Assad.
Some 65,000 children under age five in Deir al-Zor are deemed vulnerable, according to the WHO’s latest estimate.
Across Syria there are 3 million children aged under five.
Before the conflict, which began with peaceful protests in March 2011 and led to a civil war, 91 percent of Syrian children were vaccinated against diseases including polio, but the rate has fallen to about 68 percent, Rosenbauer said.
Polio invades the nervous system and can cause irreversible paralysis within hours.
It is endemic in just three countries — Nigeria, Pakistan and Afghanistan — raising the possibility that foreign fighters imported the virus into Syria, where Islamist militant groups are part of the splintered array battling Assad’s forces.
With about 4,000 refugees fleeing Syria every day, immunization campaigns for polio and other major childhood diseases — mumps, measles and rubella — are planned in neighboring countries, where there may be gaps in coverage.
“Of course this is a communicable disease. With population movements it can travel to other areas. So the risk is high of (its) spread across the region,” Rosenbauer said.
