Abstract:
To evaluate clinical characteristics and identify risk factors associated with severe outcomes in outpatients infected with the Omicron subvariant BF.7, data were collected from outpatients diagnosed with Corona Virus Disease 2019 from December 19, 2022 to January 5, 2023. Clinical characteristics were analyzed using descriptive statistics. Univariate and multivariate logistic regression analyses were conducted to identify factors associated with serious outcomes. Variables with a p 〈 0.10 in the univariate analysis were included in the multivariate model. Our study analyzed 770 patients, of whom 380 (49.4%) were male, with a median age of 59. The most common symptoms reported were cough (71.2%), fever (64.7%), and sore throat (37.7%). Fever lasted an average of 5.93 ± 3.37 days for the general population and 10.64 ± 7.12 days for impaired‐immunity patients. Most cases were mild (68.7%), followed by moderate (27.1%). Severe cases accounted for 2.2%, with 0.5% critically ill. Serious outcomes occurred in 4.2% of cases, with 11 deaths during follow‐up. Underlying‐diseases patients had a higher rate of serious outcomes. Factors associated with serious outcomes included receiving a three‐dose vaccination (odds ratio [OR] = 0.324, 95% confidence interval [CI] : 0.113–0.932, p = 0.037), male gender (OR = 2.890, 95% CI: 1.107–7.548, p = 0.030), age (OR = 1.060, 95% CI: 1.024–1.097, p = 0.001), and chest tightness or dyspnea at the time of visit (OR = 4.861, 95% CI: 2.054–11.507, p 〈 0.001). Our study found that cough, fever, and sore throat were the most common symptoms reported by patients. Receiving a three‐dose vaccination was protective, while male gender, age, and chest tightness or dyspnea were identified as risk factors for serious outcomes.
