Which of the following statements is TRUE?

参考解析：

细节理解题。根据文章倒数第二段“The WHO said its greatest worry was the potential for the virus to spread to countries with weaker heath systems, who might not be able to handle it”可知，世界卫生组织最担心的是病毒传播到卫生系统较弱的国家的潜在性。这些卫生系统较弱的国家可能无法处理这种新冠病毒，因此A项正确；根据文章第四段第一句“The new coronavirus has got attention because of its similarity to SARS which killed about 800 people across the world in 2002-2003”可知，非典在2002-2003年间在全球造成800人死亡，因此B项错误；根据文章第五段第三句“Those who have made holiday plans might have their plans affected in some parts of the world.”可知，那些制定了假期计划的人可能会影响他们在世界的某些地方旅行的计划，因此C项错误；根据文章第四段第二句“So far, the new coronavirus does not seem to be as deadly as SARS, but there have been more cases”可知，新型冠状病毒的传播不可能立即停止，因此D项错误。故选A。
