For HIV, the rate at which a given population tests positive on the ELISA test for HIV antibodies. The seroprevalence rate is nearly the same as the rate of HIV infection in a given population, leaving out mainly those who were recently infected.
As related to HIV infection: The proportion of persons who have serologic (i.e., pertaining to serum) evidence of HIV infection at any given time. See also Serum.
The total number of people showing antibodies.
The incidence of disease in a given population.
Frequency of occurrence of antibodies in a sample, expressed as a proportion or in percent.
The percent of a population testing positive for infection in a blood test. In the context of this report, the percent testing positive for antibodies to HIV.
The level of infection within a specific target population to date. Seroprevalence studies test blood samples from at risk populations to find the percentage of sampled persons infected, regardless of when infection occurred. (sero=blood)
the rate of HIV-infected individuals in a given population as measured by blood antibody tests, that is, the number of infected individuals divided by the total number in the population.
The number of a population or group (identified by their behaviors) who are infected with HIV.
Seroprevalence is the number of persons in a population who test positive for a specific disease based on serology (blood serum) specimens; often presented as a percent of the total specimens tested or as a rate per 100,000 persons tested. As positively identifying the occurrence of disease is usually based upon the presence of antibodies for that disease (especially with viral infections such as Herpes Simplex and HIV), this number is not significant if the specificity of the antibody is low.
