U.S. map of international airports participating in the TGS program, and the type of sampling conducted at each
Nasal swab samples collected from arriving international travelers provide data for detecting pathogens of public health concern that are circulating globally. All traveler samples are collected voluntarily, and participation is anonymous.
The process
Wastewater from airplanes can be tested to detect traces of pathogens shed when infected travelers use the bathroom or wash their hands while onboard an airplane. Monitoring wastewater from international flights is an effective tool to track pathogens that are circulating globally, before they spread into communities.
The process

Wastewater collected from airplanes can help us detect diseases before they spread more widely.
