【美国50岁以下成人及18岁以下青少年住院率刷新纪录】据美国有线电视新闻网8月20日报道，美国疾控中心的数据显示，全美各地的新冠肺炎入院患者数激增，其中18岁以下青少年和50岁以下成年人的住院率达到了疫情以来的最高值。其中增长幅度最大的是30至39岁的成年人以及18岁以下的青少年，这两个年龄段的住院率都比此前的峰值高出30%以上。此外，所有年龄段的总体住院率仍低于今年1月的最高值。美国疾控中心表示，如果入院治疗患者数按照目前的速度增长，那么所有年龄段的总体住院率可能会在一个月内达到新高。The COVID-19 hospitalization rate for children in the U.S. hit its highest levels ever, the Centers for Disease Control and Prevention (CDC) was quoted by CNN as saying on Friday. As for adults, every age group under 50 has also surpassed its previous record of hospitalization, said the report, adding that "the biggest increase was in adults ages 30 to 39 and children under 18, both of which were more than 30 percent higher than their previous peak." The current rate of hospitalization for all ages is still below the figure in January, but considering more than 11,000 new hospital admissions have been recorded over the past week, the U.S. might reach a new record high within a month, according to the CDC.
