Penetration and aerosolization of cough droplet spray through face masks: A unique pathway of transmission of infection

The advent of the COVID-19 pandemic has necessitated use face masks, making them an integral part daily routine. Face masks occlude infectious droplets during any respiratory event contributing to source control. In current study, spray impingement experiments were conducted on porous surfaces like having a different porosity, pore size, and thickness. mimics actual cough or mild sneeze with respect droplet size distribution (20–500 [Formula: see text]) velocity scale (0–14 text]), which makes experimental findings physiologically realistic. penetration dynamics through mask showed that all sizes beyond critical penetrate fabric atomize into daughter in aerosolization range, leading harmful effects due extended airborne lifetime aerosols. By incorporating characteristics along surface tension viscous dissipation fluid passing mask, multi-step criteria have been formulated. after atomizing multi-layered its discussed. Moreover, virus-emulating particle-laden surrogate are used study filtration entrapment virus-like nanoparticles mask. Furthermore, efficacy from perspective susceptible person investigated.
