Gaza's ceasefire reveals a health nightmare

As Gazans return to what is left of their homes, they're facing new risks on top of monumental health challenges. The 15-month war, which has killed more than 47,000 people and displaced most of the population of 2.3 million, left a health system in shambles and large swaths of the territory reduced to rubble. A shortage of clean water and damaged sewer systems have spurred worries over the spread of infectious disease. Now aid groups are rushing to provide food and supplies amid a fragile ceasefire between Israel and Hamas while planning the best way forward.
