original passage: Local tetanus is an uncommon form of the disease, in which 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.
original sentence: Local tetanus is an uncommon form of the disease, in which people have persistent contraction of muscles in the same anatomic area as the injury.
sentence2: From this passage we know that localized tetanus has a fatality rate of 1%.  Given how common or uncommon local-tetanus cases are said to be, would you expect that the overall death rate from all forms of tetanus would be very close to, and just a bit higher than 1%, since that is just the way that averages work?
