Close proximity, including conversations at closer than three (3) feet apart, facilitates disease transfer via airborne pathogens. This transfer can be mitigated by the present invention, which is directed towards methods, systems and apparatuses to produce a predictably shaped and minimally intrusive air barrier that may comprise an airborne disinfectant, to divert and or render harmless and to divert and negate close proximity airborne pathogens, such as influenza and severe acute respiratory syndrome, etc., and other airborne particulates transferred from an infected person towards the face of an unfortunate recipient at normal conversational distances apart from each other, and/or to divert and render harmless such airborne particulates.
