It was assumed that there is a 30-year latency between time of infection and acute peptic ulcer disease; half of the people with acute peptic ulcer disease experience chronic peptic ulcer disease for the duration of their lives.

It was further assumed that a small proportion (1.5%) of infected people develop cancer secondary to the H. pylori infection and that the cancers are diagnosed around age 70 and that these people die within a year. HUI states associated with these latent conditions range from .40 for acute complications of peptic ulcer disease to .74 for recurrences of chronic, mild peptic ulcer disease, to .82 for the average state during the year of life from diagnosis of cancers to death.

Table A7–3 summarizes the health care costs incurred by H. pylori infections. For the purposes of the calculations in this report, it was assumed that
