text_A: Local tetanus is the most likely form of the disease, and causes people have persistent contraction of muscles in the same anatomic area as the injury. The contractions may persist for many weeks before gradually subsiding. Local tetanus is generally milder; only about 1% of cases are fatal, but it may precede the onset of generalized tetanus.
text_B: A reader with a passing familiarity with medicine might recall that tetanus was known as lockjaw in the middle ages, which suggests that in the majority of cases, tetanus infected the body in general rather than just a small area around a cut or wound.  Does the passage make it sound like this is still the case?
NO.
