ABSTRACT
OBJECTIVES:
To calculate the seroprevalence of asymptomatic healthcare workers (HCWs) in our institution.METHODS:
We conducted a cross-sectional study among asymptomatic HCWs in a large hospital during the peak of the pandemic (from July to August 2020 and followed them up until February 2021) in Riyadh, Saudi Arabia. We collected the data in a Microsoft Word document after collecting a single serum sample for detection of antibodies from each participant then we compared the results statically in Microsoft Excel tables.RESULTS:
We enrolled 188 participants and measured their IgG antibodies from venous blood samples using CLIA. Six (3.2%) had positive antibodies despite being asymptomatic. Most of these were from non-COVID-19 working areas (4 out of 6), but all had an exposure with a positive COVID-19 patient at some point in the preceding 2 months.CONCLUSIONS:
Our results are consistent with similar local studies showing low seroprevalence among HCWs while most positive cases are from non-COVID-19 areas. Despite this low seroprevalence, HCWs are still considered a high-risk group; hence, there is a need to encourage strict implementation and adherence to infection control measures and vaccination among HCWs, especially when these measures are relaxed on the national level.Keywords
