The Centers for Disease Control and Prevention (CDC) will require foreign travelers heading to the United States to certify that they have not traveled to the Democratic Republic of Congo (DRC) in the last three weeks, according to a report from The Hill. The Hill described the new requirement as coming amid a "widespread outbreak of Ebola." The Hill's summary describes the rule as applying to foreign travelers heading to the U.S. and does not describe any exemptions.

Reuters first reported the requirement on Thursday, citing a CDC memo, according to The Hill's summary of the story. The summary does not include Reuters' own wording or the text of the memo, so the details attributed to the memo are limited to what The Hill relayed.

The Hill's summary ties the requirement to travel to the DRC but does not give case counts, locations within the country, or the number of travelers who may be affected.

The summary also does not say when the requirement takes effect, how travelers will provide the certification, or how the CDC plans to enforce it. The Hill's article is credited to reporter Ryan Mancini, and the summary available for this story is incomplete, ending mid-sentence. Those questions remain unanswered in the material available for this report.

Because this story relies on a single summary, the account of the requirement is limited to three points The Hill reported: the certification requirement for foreign travelers, the three-week window tied to travel to the DRC, and the CDC memo that Reuters first cited on Thursday.
