Respirators (N–95 and N–100; both commercially available) are masks designed to shield the wearer from inhalational hazards, as opposed to surgical masks, which are designed to protect others from contaminants generated by the wearer.

It has long been a puzzle why,in temperate climates, influenza occurs in epidemics only in the winter months,45 why epidemics cease before all those susceptible have been infected, and why influenza outbreaks have occurred simultaneously in geographic sites great distances from each other, where direct contact between those sites was not possible.3 The mystery has been such that 1 reputable journal has published a theory arguing for viruses from space, via cosmic dust, as being responsible for influenza epidemics.46
