瑞典卫生部昨天的新闻发布会提出了今年春天瑞典可能出现的瘟疫大流行的三种场景设想。
首席流行病学家Anders Tegnell说:“第三波疫情极有可能会爆发。”根据卫生部的一种设想,第三波感染高峰可能由两种因素促成:一是由于人与人之间接触的增加;另一个危险因素是传染性更强的变异病毒所致。在周四的联合新闻发布会上,Anders Tegnell谈到“第三波高峰”时说:“预计它将来得很快,几周内就会开始。”
卫生部提出的另外两种场景比较乐观,但这位首席流行病学家不认为未来的感染趋势会向下发展。
瑞典目前处于第二波感染阶段。卫生部Johan Carlson在新闻发布会上说,虽然感染发展曲线已经趋于平稳,但当前感染的传播仍然非常广泛。“尽管疫苗接种已经开始,但我们还需要一段时间才能看到接种对感染传播的影响。”Johan Carlson 提醒民众要遵循为防止病毒进一步传播而提出的建议。Johan Carlson说,“即使在遵守限制方面发生微小的改变也会产生重大后果。随着人与人接触的增加,再加上变异病毒的高传播性,瑞典可能会在春季引发第三波高峰。在最坏的情况下,感染的发展将会迅猛而有力。”卡尔森说。
