Lymes disease is contracted in humans in only one way.

First of all, no one with any disease is going to be "guaranteed". I'm guessing you mean quarantined. A person infected with TB is highly infectious and the disease can easily be spread, therefore the infected person is isolated to contain the spread of the disease.
There are quite a few ways to become immune to smallpox. One way is that you can be infected with the disease Cowpox. Which is not deadly in anyway but is a disease nobody wants to have. Another way is, you can infect your self with smallpox and give yourself a mild case of it. It is proven that once you had smallpox and you survived you never get it again, by infecting yourself mildly you can become immune to it. Correction mild case of smallpox is cowpox if u become infected with cowpox u become immune to smallpox and cowpox for the rest of your life it is like a vaccination but instead of being shot with it u actually become sick but once you get over it your completely immune to it or any other more serious case of the illness.
