Longevity of Immunoglobulin-G Antibody Response Against Nucleocapsid Protein Against SARS-CoV-2 Among Healthcare Workers.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused the latest pandemic and the most significant challenge in public health worldwide. Studying the longevity of naturally developed antibodies is highly important clinically and epidemiologically. This paper assesses the longevity of antibodies developed against nucleocapsid protein amongst our health-care workers.

A Cohort Study of Seroprevalence of Antibodies Against SARS-CoV-2 Infection Among Healthcare Workers at a Tertiary Hospital in Saudi Arabia.

Background: The nature of the healthcare workers' jobs standing at the frontline against the coronavirus disease 2019 (COVID-19) puts them at a higher risk of unknowingly contracting the disease and potentially contributing to the spread. This study aims to assess the overall positive seroconversion prevalence of SARS-CoV-2.

Methods: This is a longitudinal cohort study of healthcare workers at Johns Hopkins Aramco Healthcare (JHAH).
