How does GIDEON calculate incidence and prevalence rates?
Click to find out where prevalence and incidence rates come from and how cases from outbreaks impact the total number of cases for a given country.
Prevalence rates are derived from Health Ministry reports and individual publications from peer-reviewed journals. When available, linked references appear for the latter.
Incidence rates are either derived directly from Health Ministry reports and publications or calculated as cases per 100,000 against an automatically updated mid-year population table in our database.
Cases from outbreaks are included in the total number of cases per year for that country. The accuracy and methods used in individual outbreaks will vary by source and cannot be used to calculate total cases per year (unless stated by the source itself).
The GIDEON infectious disease database offers unique insights you won't find anywhere else.
