  • Tests showed FEND's aerosol suppression effects lasted several hours after administration, researchers reported. (upi.com)
  • In a third study, researchers compared the effects of surgical masks and FEND use among a group of adults and children. (upi.com)
  • When researchers excluded one outlier individual, they found exhaled aerosols were reduced by 59 percent by masks and 87 percent by FEND usage. (upi.com)
