Michal Ruprecht was 2 AM into his journey home from Uganda when the airline agent gave him a look of disbelief. The medical student and freelance reporter, who’d spent a month reporting stories for NPR in East Africa, thought he was heading to Michigan. Instead, a memo from U.S. Customs and Border Protection told him otherwise: he had to land at Washington Dulles International Airport in Virginia.
“The first thing that was going through my head was denial,” Ruprecht recalls. “I wasn’t sure if this was real.”
He wasn’t alone. Just hours before his early morning departure, the U.S. announced a new policy routing all Americans who’d transited through Uganda, South Sudan, or the Democratic Republic of Congo within the past 21 days through three designated airports: Dulles, Atlanta’s Hartsfield-Jackson, and Houston’s George Bush Intercontinental. The move came as the World Health Organization declared the Ebola outbreak in East-Central Africa a public health emergency of international concern, with over 800 suspected cases and more than 180 suspected deaths already recorded.
It’s the kind of decisive action that sounds reasonable on a policy memo. In practice, it created chaos and raised some uncomfortable questions about whether we’re actually making anyone safer.
Temperature Checks and Tarps
After 20 hours of travel, Ruprecht arrived at Dulles and was flagged for additional screening. CDC officials had erected what he describes as a “makeshift campsite” of temporary clinic spaces separated by tarps. A thermometer was pointed at his forehead. His first reading came back slightly elevated, which the official chalked up to nerves. The next two checks were normal.
The screening lasted maybe 5 to 10 minutes. He answered questions about symptoms and his activities in Uganda, received a text with Ebola warning signs, and caught his connecting flight home.
Anticlimactic, as Ruprecht himself noted. But that’s partly the point. The CDC is trying to balance vigilance with logistics. After the initial screening at the three hub airports, state health departments take over, monitoring travelers based on their exposure risk. Some get daily check-ins. Others, less intensive follow-up.
Virginia’s state epidemiologist, Dr. Laurie Forlano, was candid about the early stages: “I think in the beginning of any response like this, a little chaos is part of the gig.” She’s right. Health departments are already dealing with measles and hantavirus monitoring, and the nation’s public health workforce has been hollowed out over the past five years. Dr. Jeanne Marrazzo, CEO of the Infectious Diseases Society of America, didn’t mince words at a May 21 briefing: “We’ve seen decimation of local, regional and state public health staffing and funding for programs.”
The Travel Ban Question
Here’s where things get thorny. The current restrictions don’t just screen travelers; they also limit who gets to enter the U.S. at all. U.S. citizens and nationals are guaranteed entry at the three designated airports. Green card holders will be considered. Everyone else? Turned away.
This represents a departure from how the U.S. handled the 2014-2016 West African Ebola epidemic, the largest on record. Back then, policymakers allowed travelers from all countries to enter under conditions requiring 21 days of daily monitoring.
Dr. Marty Cetron, who formerly headed the CDC’s Division of Global Migration and Quarantine, has studied the effectiveness of travel bans. His conclusion: they rarely work. “When people feel like there’s a restriction but they have a desperate need to travel, they will often find a way,” he says. People don’t disappear. They route around the system.
During the 2014-2016 outbreak, U.S. health officials found success with education and compliance. “If you can educate people on how to do this safely and what the goals are for them, their family and the communities they’re joining, they’re often more likely to be compliant,” Cetron explains.
The Real Problem Is Somewhere Else
Here’s the uncomfortable truth: airport screening and travel restrictions are largely performative when it comes to stopping epidemics. They make us feel like we’re doing something, and they do catch some cases. But they don’t address where outbreaks are actually defeated: at the source.
Cetron is blunt about the math: “We’re not going to be safe enough if that’s the main priority and it comes at the expense of doing other things that are more impactful.” Pathogens don’t care about borders. To actually end the danger, you have to stop the virus where it’s spreading.
The CDC currently has several dozen staff in the affected East-Central African countries. During the 2014-2016 West African epidemic, the U.S. deployed over 3,000 personnel from the military, CDC, and USAID. That kind of surge response takes resources, coordination, and political will. Last year, USAID was abruptly shuttered, which doesn’t exactly signal long-term commitment to containing diseases abroad.
The argument isn’t whether screening is worthless. It’s about what we’re willing to invest in. We’re spending considerable effort routing travelers through three U.S. airports while the actual outbreak burns in Uganda and the DRC. One of those interventions prevents infections within U.S. borders. The other prevents infections everywhere.
The real question is whether we actually believe that matters more than theater at the airport.
