A 10-month-old unvaccinated baby in Gaza has contracted polio, the first case in 25 years, resulting in partial paralysis. WHO head Tedros Adhanom Ghebreyesus expressed grave concern and announced plans for a vaccination program. The UN attributes the re-emergence to war-related disruptions in vaccination and damage to water systems. A week-long ceasefire is being urged to vaccinate over 640,000 children. UN Secretary General António Guterres warned that hundreds of thousands of children in Gaza are at risk.
