Air monitor can detect COVID-19 virus variants in about 5 minutes

Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of the SARS-CoV-2 virus variants in a room in about 5 minutes.

Indoor Air-Cleaning Strategies Are Key to Minimizing Virus Spread

Along with vaccines, masks, and testing, indoor air hygiene and building engineering controls will be key to slowing the spread of airborne, highly infectious variants of COVID-19. In a recent review in the journal Indoor Air, researchers at Berkeley Lab presented a thorough review of the state of the science for several key strategies to reduce airborne infection risk using building controls – ventilation, filtration, airflow management and disinfection by germicidal ultraviolet (UV) light.

Indoor Air Quality Study Shows Aircraft in Flight May Have Lowest Particulate Levels

If you’re looking for an indoor space with a low level of particulate air pollution, a commercial airliner flying at cruising altitude may be your best option. A newly reported study of air quality in indoor spaces such as stores, restaurants, offices, public transportation — and commercial jets — shows aircraft cabins with the lowest levels of tiny aerosol particles.
