CAIRO, Aug 7 (Reuters) - The World Health Organisation is working on a polio vaccination campaign for Gaza after the virus was detected there, officials say, although the absence of a ceasefire in Israel's
war with Hamas presents multiple roadblocks.
Gaza's health ministry declared a
polio epidemic in the Palestinian enclave last month, blaming Israel's ongoing military offensive.
While no clinical cases have been found so far, polio was detected in sewage in Gaza's Deir al-Balah and Khan Younis governorates, Dr. Hamid Jafari, a WHO polio specialist, said during a news conference on Wednesday, adding it was possible the virus had been circulating since September.
