System and method to reduce risk of exposure to pathogens using a system comprising transportable clinical chambers, often configured with the exterior dimensions of a shipping container. The transportable chamber can be partially or completely self-contained, and configured for rapid transport and setup. The chamber is typically equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, and automatic air control devices. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filling at least a portion of the chamber with an air-phase anti-pathogen agent. After sterilization, the invention deactivates the generator and then restores the connection to outside sterilized air. In some embodiments, the transportable chamber also comprises an intelligent platform comprising video cameras, and computer vision systems configured to identify humans and medical supplies, read optical tags, and correlate recognized objects with RFID tag data.
