Infographic of CDC Cyclospora outbreak data: 1,947 confirmed cases across nine states, at least 98 hospitalizations, and no deaths. Panel A shows apparent peaks on June 24 and July 9; Panel B shades the six-week reporting-lag window, emphasizing that the curve remains provisional.

Cumulative Hazard of Hepatitis E.
The cumulative hazard of a first hepatitis E episode (i.e., the incidence rate) was estimated as a minus-log transformation (log data to nonlog data) of the Kaplan–Meier survival curve during the period after the administration of the first dose of study drug until the end of the study among all subjects who received at least one dose of either vaccine or placebo. The numbers below the graph are the numbers of patients in each group remaining under surveillance at 100-day intervals. The difference between subjects who received placebo and those who received vaccine was significant (P<0.001 by the log-rank test). Vaccine efficacy from the first dose, calculated with the Cox regression model, was 89.9% (95% CI, 77.9 to 94.5%).
