Root Explanation

Seroprevalence → It is formed from "sero-" (from Latin "serum", meaning serum or fluid) and "prevalence" (from Latin "praevalentia", meaning strength or power). The term refers to the level of a particular substance in a population's serum, indicating how widespread a disease or condition is within that population.

Memory Tip

Think of 'serum' ('sero-') as the fluid in which we measure the 'strength' or occurrence ('prevalence') of a disease in a population.
