It is not yet clear whether the Omicron COVID-19 variant is more transmissible, or causes more severe disease compared to other variants including Delta, the World Health Organization said on Sunday.

世界卫生组织11月28日表示，目前还不清楚奥密克戎毒株是否比德尔塔毒株等新冠病毒变异株传染力更强，或是将引发更严重的疾病。

Preliminary data suggest there are increasing rates of hospitalization in South Africa, which may be due to increasing numbers of people becoming infected.

初步数据显示，南非的住院率攀升，不过这可能是因总体染疫人数增加。

The WHO confirmed there is currently no information to suggest symptoms associated with Omicron are different from those from other variants, as understanding the level of severity of the Omicron variant will take days or weeks.

世卫组织证实，目前没有证据表明奥密克戎毒株引发的症状与其他变异株引发的症状不同，探究奥密克戎毒株的严重程度，还需要数日至数周的时间。

However, the WHO said preliminary evidence suggests there may be an increased risk of reinfection with Omicron, but information is limited.

世卫组织称，就初步掌握的证据分析，由奥密克戎变异株引发的再感染风险可能更高，但证据十分有限。

It added current PCR tests continue to detect Omicron, while further studies are ongoing to understand how the Omicron variant will impact available vaccines and treatments for COVID-19.

目前继续以PCR筛检确诊病例，并且仍在进行相关研究，以判别奥密克戎毒株是否对于目前的新冠疫苗和确诊后的治疗造成影响。
