The US Food and Drug Administration (FDA) has urgently withdrawn approval for the use of aerosol boxes that have been used globally to protect healthcare workers from COVID-19.
Studies have found that these boxes potentially increase the healthcare worker’s risk of exposure to aerosolized and droplet particles that potentially contain SARS-COV-2, the virus that causes COVID-19, by up to 500%.
