Repeated Antigen-Based Rapid Diagnostic Testing for Estimating the Coronavirus Disease 2019 Prevalence from the Perspective of the Workers' Vulnerability before and during the Lockdown.

ABSTRACT:

Background

No previous study has investigated the SARS-CoV-2 prevalence and the changes in the proportion of positive results due to lockdown measures from the angle of workers' vulnerability to coronavirus in Greece. Two community-based programs were implemented to evaluate the SARS-CoV-2 prevalence and investigate if the prevalence changes were significant across various occupations before and one month after lockdown.

Methods

Following consent, sociodemographic, clinical, and job-related information were recorded. The VivaDiag™ SARS-CoV-2 Antigen Rapid Test was used. Positive results confirmed by a real-time Reverse Transcriptase Polymerase Chain Reaction for SARS-COV-2.

Results

Positive participants were more likely to work in the catering/food sector than negative participants before the lockdown. Lockdown restrictions halved the new cases. No significant differences in the likelihood of being SARS-CoV-2 positive for different job categories were detected during lockdown. The presence of respiratory symptoms was an independent predictor for rapid antigen test positivity; however, one-third of newly diagnosed patients were asymptomatic at both time points.

Conclusions

The catering/food sector was the most vulnerable to COVID-19 at the pre-lockdown evaluation. We highlight the crucial role of community-based screening with rapid antigen testing to evaluate the potential modes of community transmission and the impact of infection control strategies.

Project description:BackgroundLittle is known on the trends of aeromedical retrieval (AR) during social isolation.AimTo compare the pre, lockdown, and post-lockdown AR patient characteristics during a period of Coronavirus 2019 (COVID-19) social isolation.MethodsAn observational study with retrospective data collection, consisting of AR between 26 January and 23 June 2020.ResultsThere were 16 981 AR consisting of 1983 (11.7%) primary evacuations and 14 998 (88.3%) inter-hospital transfers, with a population median age of 52 years (interquartile range 29.0-69.0), with 49.0% (n = 8283) of the cohort being male and 38.0% (n = 6399) being female. There were six confirmed and 230 suspected cases of COVID-19, with the majority of cases (n = 134; 58.3%) in the social isolation period. As compared to pre-restriction, the odds of retrieval for the restriction and post-restriction period differed across time between the major diagnostic groups. This included, an increase in cardiovascular retrieval for both restriction and post-restriction periods (odds ratio (OR) 1.12, 95% confidence interval (CI) 1.02-1.24 and OR 1.18 95%, CI 1.08-1.30 respectively), increases in neoplasm in the post restriction period (OR 1.31, 95% CI 1.04-1.64) and increases for congenital conditions in the restriction period (OR 2.56, 95% CI 1.39-4.71). Cardiovascular and congenital conditions had increased rates of priority 1 patients in the restriction and post restriction periods. There was a decrease in endocrine and metabolic disease retrievals in the restriction period (OR 0.72, 95% CI 0.53-0.98). There were lower odds during the post-restriction period for retrievals of the respiratory system (OR 0.78, 95% CI 0.67-0.93), and disease of the skin (OR 0.78, 95% CI 0.6-1.0). Distribution between the 2019 and 2020 time periods differed (P < 0.05), with the lockdown period resulting in a significant reduction in activity.ConclusionThe lockdown period resulted in increased AR rates of circulatory and congenital conditions.
