Evaluation of Anti-SARS-CoV-2 IgG Antibody in Healthcare Professionals Infected with COVID-19

Background: The knowledge of antibody’s significance and frequency in patients cured severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is extremely limited. Objectives: This study aimed to evaluate anti-SARS-CoV-2 IgG antibodies exposed SARS-CoV-2. Methods: Healthcare professionals infected with SARS-CoV-2 were enrolled this study. levels detected 15 days after the onset symptoms five months later. Results: A total 167 disease 2019 (COVID-19) evaluated, including 119 (71.3%) females 48 (28.7%) males. Of 88 polymerase chain reaction (PCR)-positive patients, 55 (62.5%) had IgG-positive antibodies, 79 reverse transcriptase (RT)-PCR-negative 12 (16.9%) antibodies. Out 23 anosmia cases, 19 (82.6%) positive There was a significant relationship between antibody (P = 0.001), but there no correlation titers gender other symptoms. Immortally, 63 (94%) cases demonstrated high infection. Moreover, 6.5% (N 11) population re-infected COVID-19 six Conclusions: Overall, detection may be an appropriate method identify suspected negative RT-PCR test. Antibodies can remain most for up seems valuable diagnostic factor, healthcare system should implement isolation measures anosmia.
