It is possible for an infected individual to produce no reaction and for a successfully treated individual to continue to produce a reaction (known as being "Wassermann fast" or "fixed").

Famous quotes containing the word uncertainty:
“I think the worst thing this nation could do for humanity would be to leave any uncertainty as to our will, our purpose and our capacity to carry out our purpose.”
—Hubert H. Humphrey (1911–1978)
“You do not mean by mystery what a Catholic does. You mean an interesting uncertainty: the uncertainty ceasing interest ceases also.... But a Catholic by mystery means an incomprehensible certainty: without certainty, without formulation there is no interest;... the clearer the formulation the greater the interest.”
—Gerard Manley Hopkins (1844–1889)
