Kern County selected for CalScope study to estimate prevalence of COVID-19 antibodies in California

April 21, 2021 /

Kern County is one of seven counties that were selected to participate a study by the California Department of Public Health (CDPH) designed to estimate how many Californians have antibodies against COVID-19.

In partnership with Stanford University and seven county departments of public health, the study will ask randomly selected households to complete an anonymous survey and a free at-home antibody test for SARS-CoV-2, the virus that causes COVID-19. The study request that one adult and one child from the selected household participate.

The study asks questions about a number of COVID-19 risk factors and the antibody test can show if a person has been infected with COVID-19 in the past or if a person has been vaccinated against COVID-19.

By looking for antibodies, we can estimate the number of people who have antibodies to the virus that causes COVID-19. This will help us understand how many people in Kern County may have been infected with COVID-19 or vaccinated up to this point.  Combined with information from the other selected counties, it will help provide an estimate for the State of California. 

Residents will receive a $20 gift card for each online survey that is completed for up to two people in the household. Residents will receive an additional $20 gift card for each completed test kit received from the household for up to two people.  Each household can receive up to $80 if both one adult and one child completes all surveys and test kits for this study.
