Chen Xiuxi explained the situation in Japan and South Korea. South Korea has decided to lift the indoor mask order at the end of January. At the same time, it is not necessary to wear a mask when entering and leaving indoor public places, but it is still necessary to wear a mask when taking public transportation and entering and leaving medical institutions; Japan is currently discussing COVID-19. -19 has been downgraded to local epidemic detection, which is the same as influenza, and the indoor mask order will be lifted. The relevant policies are expected to be implemented in April. Therefore, when considering policies such as downgrading and mask order lifting, it is necessary to consider the community immune protection formed by natural infection. Considering factors such as the protective power of bivalent vaccines, the affordability of medical treatment is the focus of careful evaluation.

Chen Xiuxi said that Taiwan's immune protection is currently around 50%, and there is a continuous growth trend. The immune protection of the statistics on January 15 reached 54%. Considering that the ethnic group has high protection of additional vaccines and some bivalent vaccines, and There is no need to further consider asymptomatic infections. The tolerable effective reproductive epidemic index (Rt value: the ability of the virus to spread to humans within a certain period of time) is 2.1. Taiwan's current Rt value is about 2.17, but in order to prevent China from Due to the impact of the epidemic and the impact of tourists returning from Europe and the United States, it is conservatively suggested that indoor masks can be removed around the end of February.
