美国疾控中心周二表示，将向宾夕法尼亚州增派支援，协助调查持续发生的麻疹疫情。
此前该州已通过疾控中心的“流行病学援助”应急响应项目正式请求联邦援助。
The US CDC said on Tuesday it would deploy additional support to Pennsylvania to help investigate the ongoing measles outbreak, as the state formally requested federal assistance through the agency's Epi-Aid emergency response program.
