He that can see a louse as far away as China is unconscious of an elephant on his nose
Just as the only reservoir for the typhus virus in nature is provided by man, so the only vector of infection is the louse. The bite of the louse is not virulent immediately after the infecting meal. It becomes so only towards the 7th day following infection.
We are a government of laws. Any laws some government hack can find to louse up a man who's down.
