After a decade of crisis, Syria remains one of the world’s most complex humanitarian crises. Continued hostilities, new and protracted displacement, increased returns and the sustained destruction of communities have impacted Syrians’ lives and futures in a devastating way. The 2021 Humanitarian Needs Overview (HNO) identified that 13.4 million people, more than half of country’s pre-crisis population, need humanitarian support. Of this figure, 12.4 million require health care.
