Measuring damage involves various epidemiological metrics and tools. Some of the key ones include: - Incidence and Prevalence: These metrics help quantify how widespread a disease is and how many new cases occur in a given time period. - Mortality Rates: These rates indicate the number of deaths caused by a disease, providing insight into its lethality. - DALYs and QALYs: These are composite measures that take into account both the quality and quantity of life lost due to diseases.
