The global health body says virus could spread even beyond Gaza if violence does not end to enable immunisation push.

The World Health Organization (WHO) says it is working on a campaign against polio in Gaza after the virus was detected there, but the continuing war presents multiple hurdles to the effort.

While no clinical cases have been diagnosed so far, polio was detected in sewage in Gaza’s Deir el-Balah and Khan Younis areas, WHO polio specialist Hamid Jafari said in a news conference on Wednesday.

“We need a ceasefire, even a temporary ceasefire to successfully undertake these campaigns. Otherwise, we risk the virus spreading further, including across borders,” said Hanan Balkhy, regional WHO director.
