Untreatable TB coming to a city near you soon

[Tartar Horde]

Getting back on topic government rant over
Within the Health service community I have spocken to a number of Dr's Surgeons etc, and they see the threat of Viral and bilogical agents, (man made or natural) as the greatest overall threat to humanity, far more so than open warfare. When i have asked for details on combatting these their responses have not reassured me at all.
Isolation and severly limited contact with other humans are their main recomendations, but you still can't tell who is carrying etc until the major symptoms kick in. With regard to TB you can become infectiouse before you start coughing etc, this is the case with other pathogens like smallpox & Ebola.
Bearing this in mind, how! as preppers do we tackle this? I'm not sure I want to wear a mask every time I go out. Becides drawing attention to myself and getting arrested, I'm far to pretty to cover my face
