Tom Frieden

Dr Tom Frieden is an epidemiologist and President of Resolve to Save Lives, a global health initiative. He served as Director of the US Centers for Disease Control and Prevention (CDC) from 2009 to 2017, overseeing the US response to the 2014-16 West Africa Ebola epidemic and the Zika outbreak. He is the originator of the 7-1-7 metric: a structured target requiring that outbreaks be detected within 7 days of first case, reported to authorities within 1 day of detection, and responded to within 7 days of report. The 7-1-7 framework is now used by WHO and partner governments to benchmark outbreak-response speed globally.

In the context of the 2026 Bundibugyo Ebola outbreak, Frieden emerged as a prominent critic of the US 21-day entry ban on nationals of DRC, Uganda, and South Sudan, which ran directly against WHO Temporary Recommendations. Frieden argued publicly that travel bans discourage transparent outbreak reporting, drive cases underground, and have historically failed to prevent international spread while imposing economic harm on affected countries. His critique carries weight precisely because of his CDC tenure: he managed the politically charged US response to the 2014 Dallas Ebola case, resisting domestic pressure for similar travel restrictions at the time.

Frieden's 7-1-7 metric provides the primary analytical lens through which the Bundibugyo response is being evaluated: with only 21% of named contacts being followed up in Ituri and the outbreak tripling in size between 17 and 21 May, the response is failing all three benchmarks in the most affected zones.
