Droplets from coughs and sneezes travel far­ther than you think

Daily Trust - - HEALTH -

It is com­mon knowl­edge that when we cough or sneeze, we should cover our mouth and nose with a tis­sue to pre­vent germs from be­com­ing air­borne. Now, new re­search sug­gests this in­struc­tion is more im­por­tant than ever; they found that droplets from coughs or sneezes can travel up to 200 times far­ther than pre­vi­ously thought. Ac­cord­ing to the re­search team, the droplets that are pro­duced when we cough or sneeze are ac­com­pa­nied by “gas clouds” that en­able the droplets to travel greater dis­tances. Past re­search has sug­gested that larger drops of mu­cus travel far­ther than smaller drops be­cause they have more strength be­hind them. How­ever, the in­ves­ti­ga­tors of this most re­cent study found that when droplets merge with the gas cloud, their tra­jec­tory is al­tered.”
