“Coronavirus with another virus” refers to illnesses that were associated with coronavirus and a second virus. The “Other Virus(es)” category refers to illnesses that were not coronavirus associated but were associated with ≥1 other viruses. Comparisons of categoric variables by 2-sided Fisher exact test. The percent of illnesses in each illness category did not differ between male and female patients in group 2 (data not shown).
∗
P < .05, greater proportion of group 1 patients who had 9 to 11 symptoms at onset of illness for illnesses without a virus identified and for all illnesses (virus identified or not), respectively, than group 2 patients.
