There seems to be a bit of a fad for scrawling vaguely scientific-sounding bollocks about viruses around here. A femtosecond isn't even a unit of size, and if latex was permeable to viruses, then condoms woudln't prevent STD transmission...
Also, of course, viruses don't generally travel alone. The size of breath droplets that would typically carry the Covid-19 virus, for example, is about 1 micron, which an N95 mask will filter out very well. Plus, you generally need to inhale a significant number of them—the "viral load" people talk about—to become infected.
