Abstract
Coronavirus Disease “COVID-19” is a new human pandemic disease has spreaded worldwide since late of 2019. SARSCoV- 2, the causative agent of COVID-19, is an emerging human coronavirus that has infected more than 572 million people around the world and caused more than 6.3 million deaths by July 2022. Seroprevalence study is an important tool to assess the level of social immunity within a target population. A total of 937 blood samples were collected from the employees of the Royal Scientific Society of Jordan in the period between January 10th and February 4th, 2021. Serum samples were harvested from the blood samples and preserved in appropriate conditions. Enzyme Linked-Immunosorbent Assay “ELISA” technique was used to detect the COVID-19 IgG antibodies in the serum samples. Demographical data and medical history data were collected from all participants to subsequently interpret the results. Out of 937, 243 (25.93%) were tested seropositive for the COVID-19 specific IgG antibodies. Surprisingly, 121 out of those tested seropositive (49.79%) were not previously tested positive for COVID-19 causative agent via PCR test. On the other hand, 26 individuals who tested positive via PCR test for COVID-19, were tested seronegative for COVID-19 specific IgG antibodies (2.77%). The results of this study revealed the significant number of undiscovered COVID-19 cases within a specific community. The study also showed the importance of conducting seroprevalence studies on national-scale in Jordan; as such studies will give a clear assessment on the Jordanian population immunity against COVID-19. In addition to help in sustaining work in many sectors in the country.
