Nurses’ Station Epicenter of One Hospital’s COVID Outbreak
Nosocomial spread of COVID-19 throughout a medical unit likely occurred through aerosol transmission from a symptomatic nurse, researchers said. An outbreak in a Boston hospital among 103 healthcare professionals and patients arose on a non-COVID ward after a nurse became symptomatic 4 days after receiving a COVID vaccine in late December 2020, reported Eric Garshick, […]
Light amplification accelerates chemical reactions in aerosols
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid droplets and very fine particles can trap light — similar to […]
