中东呼吸综合征是由一种冠状病毒引起的肺部感染疾病，也叫做MERS-Cov。
冠状病毒能在冬季引起类似感冒的疾病，但这种冠状病毒与感冒病毒不同，此前未曾在人类身上发现过。
大多数患中东呼吸综合征的人都曾经到过或居住在阿拉伯半岛地区，又或者与到访过该地区的人有过密切接触。
大多数患者会表现出严重的呼吸系统疾病症状，包括：发烧、咳嗽以及呼吸急促。
【讲解】文中的MERS就是“中东呼吸综合征”的意思，即为Middle East Respiratory Syndrome，其中syndrome意为“综合征”，是医学术语，指机体同时出现的一系列症状，如：Lemon juice can help to prevent economy-class syndrome by improving blood circulation. (柠檬汁能够改善血液循环，有助于预防经济舱综合征。)
最后一句中的infect是及物动词，意为“传染，感染”，后面常接with表示“把……传染给……”，如：The water was infected with germs. (这些水被细菌污染了。)
