CDC Orders Ebola Screening for Travelers at Major U.S. Airports, Including O’Hare

Outbreak Context
A rare Bundibugyo strain of Ebola is spreading in the Democratic Republic of Congo, Uganda and South Sudan. Health authorities have confirmed 51 cases, recorded 139 suspected deaths and identified nearly 600 suspected cases across the three nations. The World Health Organization has declared the situation a public-health emergency of international concern.
Federal Screening Order
On Monday the Centers for Disease Control and Prevention issued a 30-day order under the Public Health Act to screen travelers who have been in the three affected countries within the prior 21 days. The order applies only to non-U.S. citizens; U.S. citizens, permanent residents and armed-forces personnel are exempt. The CDC initially listed five hubs—Chicago O’Hare International Airport, John F. Kennedy International Airport, Washington-Dulles International Airport, Hartsfield-Jackson Atlanta Airport and Los Angeles International Airport—for enhanced screening. At designated points, temperature checks, exposure questionnaires and contact-tracing data are collected. Travelers who develop fever are taken to an on-site quarantine station; those who clear screening receive a care kit with instructions to monitor temperature twice daily for 21 days. The agency will hold a briefing on the outbreak Wednesday afternoon.
Local Public Health Perspective
Chicago’s Department of Public Health clarified that the airport’s Port Health Station continues routine infectious-disease surveillance but no enhanced Ebola screening is currently being performed at O’Hare. Dr. Emily Landon, an infectious-diseases specialist at the University of Chicago Medicine, described the response as a “multilayered approach” and argued that directing all at-risk travelers to a single entry point, such as Dulles, would concentrate resources and avoid straining other airports.
Conflicting Reports on O’Hare Screening
The CDC’s original directive named O’Hare as a screening site, yet Chicago officials reported the absence of such measures. A Department of Homeland Security memo obtained by CBS News states that all commercial flights from the three African nations will be routed to Washington-Dulles for enhanced screening, effectively superseding the earlier airport list. This discrepancy between the federal order and local implementation has created uncertainty about where arriving travelers will be screened.

- “This is a multilayered approach that requires many different parts of the government to work together,” — Dr. Emily Landon, infectious diseases specialist, University of Chicago Medicine
- “That's just old fashioned public health contact tracing, boots on the ground, identifying who's infected, who did they have come in contact with, and trying to put them in quarantine if they're infected, isolate them, use protective equipment,” — Dr. John Lapook, CBS News chief medical correspondent
- “Ebola is one of the most infectious diseases out there. I'm not an alarmist, but I'm very concerned,” — Dr. Tyler Evans, CEO, Wellness Equity Alliance
- “the scale of the epidemic is much larger,” — Tedros Adhanom Ghebreyesus, WHO Director-General
Implications for U.S. Public Health
The screening protocol seeks to prevent Ebola’s introduction while the CDC completes a full risk assessment. By identifying potentially exposed travelers before symptom onset, authorities aim to integrate them into the national contact-tracing system and limit community spread. CDC officials have repeatedly emphasized that the immediate risk of domestic transmission remains low.
Upcoming Actions
The CDC briefing scheduled for Wednesday will review the effectiveness of the screening measures, and the 30-day order will be reassessed before it expires.
