Prospective cohort study of workers diagnosed with COVID-19 and subsequent unemployment

The purpose of this study was to investigate the relationships of workers being diagnosed with coronavirus disease 2019 (COVID-19) and being identified as close contacts of infected persons with unemployment in Japan.

This was a prospective cohort study using questionnaires about COVID-19 administered to Japanese workers. A baseline survey conducted on December 22-25, 2020, was used to determine history of being diagnosed with COVID-19 or being identified as a close contact of an infected person. Unemployment since the baseline survey was ascertained with a follow-up survey on February 18 and 19, 2021. The odds ratios (ORs) of unemployment were estimated using a multilevel logistic model with adjusted covariates nested in prefecture of residence.

Women (n = 8771) accounted for 44% of the total sample (n = 19 941), and the mean age was 48.0 years. In terms of unemployment because of negative reasons, the multivariate analysis showed that the OR of unemployment associated with being diagnosed with COVID-19 was 2.40 (95% CI: 1.15-5.01) and that the OR associated with being identified as a close contact was 0.98 (95% CI: 0.31-3.11).

There is an association between workers being diagnosed with COVID-19 and unemployment. The reason is not clear, but if the unemployment is unwanted by the individual, workplace adjustment may help prevent unwilling unemployment.
