埃博拉病毒:超级传播者是 60% 病例的原因

2017-02-15 佚名 医纬达

一项新研究报告,2014 年-2015 年西非疾病流行期间,约 3% 的人埃博拉病毒感染者是造成全部病例中 61% 病例的原因。


一项新研究报告,2014 年-2015 年西非疾病流行期间,约 3% 的人埃博拉病毒感染者是造成全部病例中 61% 病例的原因。

根据《美国科学院学报》(Proceedings of the National Academy of Sciences)本周发表的这项研究的作者的观点,控制病毒的超级传播者能预防近三分之二的病例。他们补充,他们的结果可能低估了控制病毒超级传播者的影响,因为这项研究仅包括有潜在安全性问题的受害者。

他们说,发现“超级传播者”,就有可能制定有针对性的公共卫生措施,在疾病流行期间控制传染病的传播。2014 年-2015 年疾病流行期间,大量资金用于整个国家范围内的埃博拉预防和控制的公共卫生活动。目前的研究表明,对于有较高传播风险和有某些类型行为的个人,此消息可能是更有用的,并能预防流行病持久发作。

本研究的合着者 Benjamin Dalziel 说“因为我们可以更多了解这些感染途径,我们应该能够更好地专注于感染风险最高和传播感染可能性最大的个人行为和人口统计的类型。”
