Pakistan's Peshawar world's 'largest reservoir' of polio: WHO
ISLAMABAD (AFP) - The World Health Organization (WHO) on Friday declared Pakistan's troubled northwestern city of Peshawar as the world's "largest reservoir" of polio and called for urgent action to boost vaccination.
Almost every polio case in 2013 in Pakistan, one of only three countries where the crippling disease remains endemic, could be linked genetically to strains of the virus circulating in Peshawar, said the WHO.
Khyber Pakhtunkhwa province, of which Peshawar is the capital, and adjoining tribal districts where Taleban and Al Qaeda linked militants have hideouts are particular polio hotspots.
Efforts to stamp out the disease have been hampered by opposition from militant groups, who see vaccination campaigns as cover for espionage, as well as long-running rumours about the drops causing infertility.
