John Bush, autorul studiului, spune că oamenii observă sau simt stropii proveniţi de la un strănut, dar nu pot vedea norul de particule, care este invizibil şi care călătoreşte mult mai departe.
De exemplu, stropii care au un diametru de 100 micrometri ajung la distanţe de 5 ori mai mari decât fusese calculat iniţial, iar stropii care au doar 10 micrometri în diametru ajung chiar şi la distanţe de 200 de ori mai mari.
Datorită acestei descoperiri, arhitecţii şi inginerii vor trebui să regândească sistemele de circulaţie a aerului din spitale, avioane şi birouri, pentru ca agenţii patogeni să nu se mai transmită uşor.
Rezultatul studiului a fost publicat în Journal of Fluid Mechanics.
