Researchers from the U.S. Army Combat Capabilities Development Command's Army Research Laboratory and UPMC created an individual biocontainment unit that uses negative pressure to suction the air from around a patient and filter out viral particles. This prevents environmental contamination and limits exposure to SARS-CoV-2.

"Outside of the current pandemic, the IBU could be rapidly deployed to isolate patients with any respiratory illness." said study co-author Dr. David Turer, a plastic surgeon who recently completed his residency at UPMC. "It's easy to see this technology used to contain influenza, MERS, or tuberculosis, particularly in places lacking advanced hospital infrastructure."
