About Incidence Rates
Incidence rate measures the frequency of new cases of a disease in a population over a specific time period. It's a key epidemiological measure for understanding disease burden and trends.

Important Notes
- Crude incidence rate: New cases per population at risk per time period
- Age-specific rates provide more accurate comparisons between populations
- Cumulative incidence measures the proportion of population that develops the disease
- Attack rate is used for outbreaks and measures the proportion of exposed who become ill
- Secondary attack rate measures transmission within households or close contacts
- Always specify the time period and population denominator when reporting rates
