<p>We interviewed every tenth pilgrim in the lines at the main entrance gates and in the designated zonal areas about symptoms of priority public health illnesses (COVID-19 and viral hemorrhagic fevers (VHF)). A suspected COVID-19 case was defined as ≥2 of: fever &gt;37.5 C, flu, cough, and difficulty breathing. A suspected VHF case was defined as fever &gt;37.5 C and unexplained bleeding. We also abstracted secondary data on 5,582 pilgrims who sought medical care for the same public health conditions at designated medical tents from Health Management Information Systems (HMIS) registers and conducted descriptive analysis.</p>
