Gaza has recorded its first polio case in 25 years, the Palestinian health ministry said on Friday, after UN chief Antonio Guterres called for pauses in the Israel-Hamas war to vaccinate hundreds of thousands of children. Tests in Jordan confirmed the disease in an unvaccinated 10-month-old from the central Gaza Strip, the health ministry in Ramallah said. According to the United Nations, Gaza, now in its 11th month of war, has not registered a polio case for 25 years, although type 2 poliovirus was detected in samples collected from the territory's wastewater in June.

"Doctors suspected the presence of symptoms consistent with polio," the health ministry said. "After conducting the necessary tests in the Jordanian capital, Amman, the infection was confirmed." The case emerged shortly after Guterres called for two seven-day breaks in the Gaza war to vaccinate more than 640,000 children.

Poliovirus, most often spread through sewage and contaminated water, is highly infectious. It can cause deformities and paralysis, and is potentially fatal. It mainly affects children under the age of five.

The UN health and children's agencies said they had made detailed plans to reach children across the besieged Palestinian territory and could start this month. But that would require pauses in the 10-month old war between Israel and Hamas, they said. "Preventing and containing the spread of polio will take a massive, coordinated and urgent effort," Guterres told reporters at UN headquarters.
