What does the term 'hyperendemic' refer to in epidemiology?

The term 'hyperendemic' refers to persistent, high levels of disease within a population. This indicates that the disease is consistently present at higher-than-expected levels in a specific geographic area or among a particular group, rather than occurring sporadically or in isolated outbreaks.

In contrast, low levels of disease would not qualify as hyperendemic, as this term specifically denotes elevated prevalence. Thoughts on disease prevention concern strategies and measures that can be implemented to reduce the incidence of hyperendemic diseases but do not describe the nature of the disease itself. Seasonal disease outbreaks are characterized by fluctuations in disease prevalence depending on the time of year, which differs from the continuous high levels implied by the concept of hyperendemicity. Thus, the definition of hyperendemicity as persistent, high levels of disease distinguishes it from these other concepts in epidemiology.
