Accelerating SARS-CoV-2 SEroprevalence SurveyS through Dried Blood Spots
The specific aims of the study are to:
* Estimate the prevalence of antibodies against SARS-CoV-2 virus among people in British Columbia (BC) Provincial Correctional Centres.
* Investigate people’s willingness and barriers to getting assessed for antibodies against SARS-CoV-2 virus among people in BC Provincial Correctional Centres.
* Determine if Dried Blood Spots (DBS) samples and venepuncture samples are equivalent for measuring the presence of antibodies against SARS-CoV-2 virus in a real world setting such as correctional centres.

- General Information on Follow Up (profile, frequency)
-
At baseline, asymptomatic and symptomatic for COVID-19 participants are tested with antibody assays (serology) and Nucleic Acid Testing (NAT). Participants are followed up depending on whether they were symptomatic or asymptomatic and the result of their test(s). If they were symptomatic and both tests (NAT and serology) were positive or one test (NAT) was positive and the other (serology) was negative, they were followed up 3 weeks after baseline. If they were asymptomatic and their test (serology) was positive, they were followed up immediately after baseline.

Timeline
Populations
ASSESS-DBS - Asymptomatic
The population is composed of people who are at least 18 years of age, incarcerated in British Columbia (BC) Provincial Correctional Centres (sentenced and remand) or staff who work in BC Provincial Correctional Centres and screened as asymptomatic for COVID-19.
Selection Criteria
- Minimum age
-
18
- Countries
-
- Canada
- Territory
- British Columbia
- Other Criteria
- Are currently incarcerated provincially in British Columbia or currently working in a British Columbia Provincial Correctional Centre
Sources of Recruitment
- Specific Population
-
- Other specific population : Incarcerated in BC Provincial Correctional Centres and staff who work in BC Provincial Correctional Centres
- Supplementary Information
-
The study will use stratified random sampling. Recruitment for this study will be facilitated by distributing information about the study to ward reps in every correctional centre, so they are able to advise residents on their ward about the study. Information will also be distributed to Corrections staff through usual staff communication channels (email distribution lists and staff notice boards, etc.) for both Corrections Officers and Correctional Health Services (CHS) staff.
