GAZA: At Shifa hospital in the Gaza Strip, nothing is sterilized, so Dr. Jamal Salha and other surgeons wash their instruments in soap. Infections are rampant. The stench of medical waste is overwhelming. And flies are everywhere. Without painkillers, patients moan while lying on metal beds lining the corridors. There’s no electricity and no ventilation amid searing heat, leaving anxious visitors to fan bedridden relatives with pieces of cardboard. Shifa, once the largest hospital in Gaza and the cornerstone of its health care system, is a shell of its former self after 22 months of war.
