Aid groups in Gaza aim to avert a polio outbreak with a surge of vaccinations

The threat of polio is rising fast in Gaza, prompting aid groups to call for an urgent pause in the war so they can ramp up vaccinations and head off a full-blown outbreak. At least one case has been confirmed and others are suspected. Polio had been eradicated in Gaza 25 years ago, but vaccinations plunged after the war began 10 months ago. Now, the territory is a breeding ground for the virus. Hundreds of thousands of displaced Palestinians are crowded into tent camps lacking clean water or proper disposal of sewage. Health authorities are preparing to vaccinate 640,000 children in the coming weeks.
