Know before it spreads! U.S. expands airport screening to Miami and Chicago to catch new infectious disease threats early

Catching the next wave? Why are passengers undergoing nasal swabbing in Miami and Chicago airport screening?

Travelers arriving at Chicago's O'Hare and Miami International Airports might soon encounter a new addition to their arrival routine: a voluntary nasal swab test at airport screenings. The Centers for Disease Control and Prevention (CDC) announced on March 12, 2024, that these two major hubs would join the agency's ongoing program to monitor the spread of infectious diseases among international travelers.

This program, initiated in 2021, already operates at six other U.S. airports. Here's a closer look at why the CDC is expanding this initiative and what it entails for incoming passengers.

Bolstering airport screening and early detection of emerging threats

The CDC's primary objective in expanding the program is to strengthen its ability to track and identify potential outbreaks of infectious diseases, particularly those originating outside the United States.

According to Allison Taylor Walker, one of the spokespersons for the CDC, Miami, and Chicago enable them to collect samples coming from areas of the world where global surveillance is not as strong as it used to be.

The program relies on voluntary participation. Passengers are approached by CDC personnel after they have cleared customs and immigration. Those who agree to participate answer a brief questionnaire about their travel history and then undergo a quick nasal swab test.

The collected samples undergo what's called genomic sequencing. This advanced technique allows scientists to analyze the genetic makeup of any viruses present, enabling them to identify known strains and entirely new ones.

This early detection capability has proven crucial in the past. The program is credited with being instrumental in the rapid identification of new COVID-19 variants, giving public health officials a head start in developing targeted mitigation strategies.

Beyond COVID-19, the program also screens for other respiratory viruses like influenza and respiratory syncytial virus (RSV). This broader approach provides valuable insights into potential outbreaks of other infectious diseases.

Addressing privacy concerns and maintaining transparency

While the program offers significant public health benefits, concerns regarding privacy are understandable. The CDC emphasizes that participation in the nasal swab test is entirely voluntary, and individuals have the right to decline the test.

Furthermore, the agency adheres to strict protocols regarding data collection and anonymity. Test results are not linked to any personal information and are solely used for public health surveillance purposes.

The CDC actively works to maintain transparency about the program. Information regarding the program's objectives, data collection procedures, and privacy measures is readily available on the CDC website.

Additionally, the agency works closely with airport authorities to ensure clear communication with arriving passengers. Informational materials are displayed in prominent locations, and personnel are available to address any questions or concerns travelers may have.

Looking ahead on a collaborative approach to global health security

The expansion of the CDC's airport screening program signifies a continued focus on strengthening the nation's defenses against emerging infectious diseases.

This initiative highlights the importance of international collaboration in global health security.

The airport program contributes to a more comprehensive global disease surveillance network by monitoring travel patterns and identifying potential outbreaks early on.

While the voluntary nature of the program might raise concerns about its effectiveness, the collected data provides valuable insights that would otherwise be unavailable. This information proves instrumental in safeguarding public health not just within the United States but also internationally.

As international travel continues to increase, the CDC's program is a crucial tool in our collective fight against infectious diseases.
