世界卫生组织12月19日发布的初步风险评估显示，将新冠变异株JN.1单独列为「需要留意的变异株」。该变异株是奥密克戎变异株BA.2，是新冠全球传播中需要高度关注的一个变异株。
目前，JN.1在全球范围内的传播速度非常快，因此世界卫生组织建议各国需要加强对JN.1的监测和管控措施，以减少其对全球公共卫生构成的风险。
不过，需要注意的是，目前的评估报告显示，JN.1对全球公共卫生构成的额外风险目前被评估为低水平。
据世界卫生组织介绍，目前全球范围内已经有多种新冠变异株，其中一些变异株具有更高的传染性和致死性。因此，对于像JN.1这样的高传播性变异株，各国需要采取更加严格的控制措施，以保护公众健康。
此外，世界卫生组织还表示，将继续密切监测各国的疫情情况，并随时发布最新的风险评估和建议。

Global attention! The World Health Organization has classified the COVID variant株 JN.1 as a “variant of concern” and单独列为需要留意的变异株. This variant is the Omicron variant BA.2, which is a highly concerning variant in the global spread of COVID.
Currently, JN.1 is spreading rapidly around the world, so the World Health Organization recommends that countries take stronger measures to monitor and control JN.1 to reduce its risk to global public health.
However, it’s worth noting that the current assessment report indicates that the additional risk posed by JN.1 to global public health is currently considered low.
According to the World Health Organization, there are already several COVID variants in circulation around the world, some of which are more contagious and deadly. Therefore, countries need to take more severe control measures to protect public health from variants like JN.1.
Furthermore, the World Health Organization says it will continue to closely monitor the situation in countries and issue updated risk assessments and recommendations.
