What “seroprevalence” means
Wiktionary · Wikipediaseroprevalence
- nounThe rate of seropositivity in a population; the proportion of a population whose blood serum tests positive for a given pathogen, especially HIV.
Seroprevalence is the number of persons in a population who test positive for a specific disease based on serology specimens, often presented as a percent of the total specimens tested or as a proportion per 100,000 persons tested. As positively identifying the occurrence of disease is usually based upon the presence of antibodies for that disease, this number is not significant if the specificity of the antibody is low.
