Globally, the COVID-19 pandemic brings different challenges to the impacted countries. To combat this pandemic, different strategies need to be tailored and implemented in countries with different situations. First, in countries with an ongoing explosion of the outbreak (i.e. the USA, Spain, and Italy), strategies suggested by the World Health Organization (WHO) which have been proven useful in China should be adopted for implementation. Secondly, countries in the regions that are still at the early stages of the outbreak (i.e., the Africa region, where many countries have only found imported cases) should further strengthen travel restrictions to reduce the risk of imported cases as well as the risk of developing local transmission. Furthermore, countries that have achieved great success in COVID control (i.e. China, South Korea, and Singapore) should continue implement the successful strategies and further roll-out strengthened new strategies to prevent new imported cases. In addition, surveillance on the genomic changes of SARS-CoV-2 is in need in all countries as some studies have found multiple mutants of SARS-CoV-2, although the impact of the mutation on the infectivity and lethality of the virus was still unclear.
在全球范围内，新冠疫情给受影响国家带来了不同挑战。为抗击这一疫情，需要针对不同情况的国家制定并实施不同策略。首先，在疫情持续爆发的国家（如美国、西班牙和意大利），应采用世界卫生组织（WHO）提出的、已在中国证明有效的策略来实施。其次，仍处于疫情早期阶段的地区的国家（如非洲地区，许多国家仅发现输入性病例）应进一步加强旅行限制，以降低输入性病例风险以及出现本地传播的风险。此外，在新冠疫情防控方面取得巨大成功的国家（如中国、韩国和新加坡）应继续实施成功策略，并进一步推出强化的新策略以防止新的输入性病例。另外，所有国家都需要对新冠病毒的基因组变化进行监测，因为一些研究已经发现了新冠病毒的多个变种，尽管这些变种对病毒传染性和致死率的影响仍不清楚。
