The epidemiological term endemic is used for any condition that persists within a particular community/locale without the need for external input of new disease, i.e. the disease in question has attained a steady-state in the affected population ¹. For this to happen the basic reproductive number (R₀) should be 1 or greater in theory, however in practice this tends to be an oversimplification, and diseases can continue under certain conditions with R₀ <1.0 ².
