Sherwal.Literature analysis:Dr. The Antibody Index was motivated. Those displaying reactive in the testing test were additional followed through to a regular basis till January 2021 for serial antibody tests. == Outcomes == The entire seroprevalence for IgG response among the employees was found to become 21.96%. Seropositivity price was observed to become considerably higher in those having a brief history of RT-PCR verified COVID-19 infections (45.09%) == Conclusions == Our research demonstrated that health care workers have an increased sero-prevalence. Our research also demonstrated the fact that antibodies developed pursuing COVID-19 infection got a waning aftereffect of defensive response following infections. Keywords:COVID-19, Serology, Virology, Immunology, Antibodies == 1. Launch == The Globe Health Company (WHO) announced coronavirus disease 2019 (COVID 19) the effect of a book coronavirus, Serious Acute Respiratory Symptoms coronavirus-2 (SARS-CoV-2) to be always a pandemic on March 19, 2020 [1]. Since that time, the virus provides wreaked havoc across continents, resulting in increased mortality, disruption and morbidity of regular lifestyle. Amidst this, health care employees are at a greater risk of disease exposure as they have been working in environments chiefly involved in the SARS-CoV-2 patient care since March 2020 especially in COVID-19 dedicated care centre like ours. This raises concerns about the safety of frontline workers as well as risk of transmission to other patients and fellow healthcare workers. SARS-CoV-2 antibody testing can prove to be a valuable tool for better understanding of prevalence of disease exposure in this population as it also adds to our existing knowledge of the extent of infection among people who are not identified through active case finding. Antibody test will be critical to know the immune status of the frontline workers. However, due to limited peer-reviewed literature, it is not yet known whether these antibodies will be protective in nature and how long will they persist in the body. Therefore, we conducted this longitudinal study to grasp the sero-prevalence of COVID-19 Tucidinostat (Chidamide) antibodies in our hospital and to better comprehend the duration of IgG response. == 2. Materials and methods == This was a longitudinal study done at Rajiv Gandhi Super Speciality Hospital spanning over a period of four months starting from October 2020 to January 2021, on healthcare workers involved in the provision of care for COVID-19 patients. A total of 305 healthcare workers were initially enrolled in the study and were divided into the following groups: a) Doctors & Nurses working in different hospital wards/Intensive Care Units & Flu Out-patient department; b) laboratory personnel and technicians in Operation Theatre, cardiology department, radiology department and SARS-CoV-2 diagnostic units; c) patient transporters/Nursing orderly/Multi-task worker; d) cleaning personnel; e) others (guards, physical therapist & administrative workers). Any participant reporting flu-like illness at the time of screening was excluded from the study group. Written informed consent was obtained from all the participants as approved by the Ethics Committee of the Institute (ECR/1436/Ins/DL/2020). After consent, the healthcare workers were asked to fill in a form that Tucidinostat (Chidamide) detailed their department, history of exposure to COVID patients, history of COVID-like symptoms and history of a positive COVID test if any. Serum samples were obtained from the study group taken as Day 0 of the study and were screened for the presence of SARS-CoV-2 IgG antibodies using semi-quantitative enzyme linked immunoassay technology from ERBAlisa (India). The Antibody Index was determined for all patients which had a positive value of 1 1.1 and negative below 0.9. The results were communicated to the tested healthcare workers with explanation about the implications of a positive or negative result. Those showing reactive in the screening test Tucidinostat (Chidamide) were further followed up on a monthly basis till January 2021 for serial antibody testing. == 3. Result == A total of 305 healthcare workers participated in the study. Initial samples were collected in the month of October 2020. The average age of participants was 33 years (range 1959 years) with male: female ratio of 1 1.9:1. Maximum participation was from nursing staff (22.62%; 69/305) followed by nursing orderly (20.32%; 62/305), housekeeping & multi-task workers (16.72%; 51/305), doctors (16.06%; 49/305), security guards (15.73%; 48/305) & technicians from various departments (8.52%; 26/305). The overall seroprevalence for IgG response among the workers was found to be 21.96% (67/305) with highest hSNFS reactive rate reported among nursing staff (27.53%; 19/69) followed by technicians included O.T, ECHO, Cath. Lab., phlebotomist & those involved in COVID-19 diagnostics (26.92%; 7/26) and security guards (22.9%; 11/48).
