Clinical characteristics of 310 SARS-CoV-2 Omicron variant patients and comparison with Delta and Beta variant patients in China
文献摘要：
Although the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant has spread,data on the clinical characteristics of infected patients are limited.In this study,the demographic,clinical characteristics,and laboratory data of 310 SARS-CoV-2 Omicron variant patients treated at Haihe Hospital of Tianjin were collected and analyzed.Information on these patients was compared to 96 patients with the Delta variant of concern(VOC)and 326 patients with the Beta VOC during the previous coronavirus disease 2019(COVID-19)outbreak in Harbin.Of the 310 patients infected with the Omicron variant,the median age was 35 years.Most patients were clinically classified as mild(57.74％),and the most common symptoms were cough(48.71％),fever(39.35％),and sore throat(38.26％).The results for different vaccination groups in the Omicron group showed that the median of"SARS-CoV-2 specific IgG"after 2 or 3 doses of vaccination was higher than the unvaccinated group(all Ps＜0.05).Older age was associated with a higher proportion of moderate cases and lower asymp-tomatic and mild cases based on clinical classifications.Compared to the Delta and Beta groups,the median age of the Omicron group was younger.The total number of asymptomatic patients and mild patients in the Omicron virus group was higher than the Delta and Beta groups(60.97％vs.54.17％vs.47.55％).This study presented the clinical characteristics of the first group of patients infected with the Omicron variant in Tianjin,China,and compared their clinical features with patients infected by the Delta and Beta variants,which would increase our understanding of the characteristics of SARS-CoV-2 Omicron variant.
