We aimed to investigate the first Omicron cases detected in France in order to assess case characteristics and provide supporting information on the possible impact of this variant on the healthcare system.
A standardized questionnaire was used to collect information from confirmed and probable Omicron cases.
Median age of 468 investigated cases was 35 years, 376 were symptomatic (89%); 64% were vaccinated with two doses and 7% had received three doses. Loss of smell and taste were reported by 8.3% and 9% of cases, respectively. Seven cases were hospitalized, three of those were unvaccinated (including two with reported precondition). No admissions to intensive care and no deaths were reported.
Our results confirm a mild clinical presentation among the first Omicron cases detected in France and highlight the importance for the national COVID-19 surveillance system to quickly detect and adapt to the emergence of a new variant.
我们旨在调查法国首例检测到的奥密克戎病例，以评估病例特征，并为该变体可能对医疗保健系统产生的影响提供支持信息。
使用标准化问卷收集确诊和疑似奥密克戎病例的信息。
468 例调查病例的中位年龄为 35 岁，376 例有症状（89%）；64%接种了两剂疫苗，7%接种了三剂疫苗。分别有 8.3%和 9%的病例报告嗅觉和味觉丧失。7 例住院，其中 3 例未接种疫苗（包括 2 例有报告的基础疾病）。无患者收入重症监护病房，也无死亡报告。
我们的结果证实了法国首例检测到的奥密克戎病例临床表现较轻，并强调了国家 COVID-19 监测系统快速发现和适应新变体出现的重要性。
