Hyperendemic
In epidemiology, the term hyperendemic disease is used to refer to a disease which is constantly and persistently present in a population at a high rate of incidence and/or prevalence (occurrence) and which equally affects (i.e. which is equally endemic in) all age groups of that population.[1][2][3][4] It is one of the various degrees of endemicity (i.e. degrees of transmission of an infectious disease).
For example, a hyperendemic state of the dengue fever is characterized by the continuous circulation of multiple viral serotypes in an area where a large pool of susceptible hosts and a competent vector (with or without seasonal variation) are constantly present.[5]
In another example, World Health Organization defines malaria to be hyperendemic if the percentage of persons with an enlarged spleen (spleen rate) is constantly greater than 50% for all age groups.[6]
