GENEVA, July 23 (Reuters) - The World Health Organization said on Tuesday there was a high risk of the polio virus spreading across the Gaza Strip and beyond its borders due to the dire health and sanitation situation in the war-ravaged Palestinian enclave.
Ayadil Saparbekov, team lead for health emergencies at WHO in Gaza and the West Bank, said circulating vaccine-derived poliovirus type 2 had been isolated from environmental samples from sewage in Gaza.
