Incidence of cases and deaths per 1 million children and case-fatality rates over time in study of predictors of fatal outcomes among pediatric patients hospitalized for Rocky Mountain spotted fever, Sonora, Mexico, 2004–2024. A) Cumulative rates; B) polynomic trends. Scale bars for y-axes differ substantially to underscore patterns but do not permit direct comparisons.
