Severity is typically measured using a combination of quantitative metrics and qualitative assessments:
Incidence and Prevalence: Incidence refers to the number of new cases over a specific period, while prevalence indicates the total number of cases at a given time. Hospitalization Rates: The number of people requiring hospital care, which can indicate the burden on healthcare facilities. Mortality Rates: The number of deaths attributed to the disease, providing a direct measure of its lethality. Severity Indexes: Composite measures that consider multiple factors, such as the Pandemic Severity Index (PSI).
