Abbreviation: CT = computed tomography.

* For cases reported as of November 5, 2019.

^† Percentages might not sum to 100% because of rounding.

^§ Self-reported symptoms (e.g., cough, chest pain, and shortness of breath).

^¶ Self-reported symptoms (e.g., abdominal pain, nausea, vomiting, and diarrhea).

** Self-reported symptoms (e.g., fever, chills, and weight loss).

^†† Three cases had missing chest radiograph information on unilateral versus bilateral findings and were excluded from this calculation.

^§§ Dates of chest radiographs and CT scans were not consistently reported, so it is unknown whether they were performed on the same or subsequent days, which could explain, in part, why the findings for the imaging tests were inconsistent among some patients.
