In the 21st century, the Syrian civil war and the Iraq War provided many examples of the devastation to servicemen and their families from the standpoint of health. There was a collapse of the healthcare infrastructure, and millions of people became internally displaced or refugees. For example, more than 1.7 million people fled Syria during the spring of 2013 and became refugees .
Prior to the war, Syria was a middle-income country. The situation has led to non-communicable diseases or exacerbations of those medical conditions as medication and health care are not always available. These patients have chronic obstructive lung disease, bronchial asthma, cancer, diarrheal infectious disease in children, and other illnesses .
