The sheer number of refugees places a huge strain on the Lebanese healthcare system. The public primary healthcare network is not fully in place and relies on an extremely expensive private sector. Despite partial subsidization and relatively low fees, many refugees struggle to access health services. In 2016, an estimated 16% of the refugee households did not receive the health care they needed, mainly due to financial concerns. About 70% of refugees from Syria in Lebanon lack valid residence. Without valid residency, refugees are at risk of arrest when crossing checkpoints, which results in limitation on freedom of movement, which subsequently curtails access to healthcare assistance.
