On Wednesday (5), the Ministry of Health announced a survey in order to understand the prevalence of COVID-19 in certain portions of the population. In all, 211,129 people, from 274 municipalities, must face serological testing in search of antibodies.
- Double antibody: how can the technique help prevent and neutralize COVID?
- USP creates test that detects antibodies to COVID-19 in 10 minutes
- Brazilian study investigates antibodies for the treatment of COVID-19
This test is carried out through a partnership with the Brazilian Institute of Geography and Statistics (IBGE), based on the National Survey by Household Samples (Pnad). The Oswaldo Cruz Foundation (Fiocruz) is also involved in the project.
The idea is to detect the response to infection and vaccination. For this, a sample of each participant must be stored in a biorepository for up to five years. Entitled PrevCov, the serological survey aims to describe the socioeconomic, demographic and epidemiological characteristics of the research participants, in addition to estimating the magnitude of coronavirus infection in capitals and metropolitan regions and allowing more accurate calculations of COVID-19 morbidity and lethality.
The project should also involve the collection of data related to recent or previous symptoms, contacts with suspected cases, testing and vaccination, as well as the participants’ entire health history. For now, there is no forecast for the conclusion of the survey, which has an investment of R $ 200 million.
