The disease spectrum of adult patients at a tertiary care center emergency department in Lebanon.

This study is the first to assess adult ED visits in a Lebanese setting. Our study suggests that patients in our population suffer from the double burden of both communicable and non-communicable disease, with coronary atherosclerosis common in admitted patients (≥ 45 years) and intestinal infections common in treat and release adult patients (19-44years), the latter condition peaking in summer and driving seasonal surges in ED visits.
