Characteristics of Omicron infection
Of the 140 patients, 125 (89.3%) had fever, 114 (81.4%) had cough, and 66 (47.1%) had malaise. Ninety percent of the patients had a combination of two or more symptoms. There was no significant difference in the frequency of symptoms between the treatment groups except for nausea and vomiting, which were more common in the two-drug combination groups. In terms of length of hospitalization, the mean length of stay was slightly longer in the combination therapy group than in the azvudine and paxlovid groups. Other comparisons between the groups are presented in Appendix Table 2.
